I have the exhaust installed with all bolts tightened, however when idling with A/C on or sometimes without A/C on I’m experiencing an exhaust rattle. What can be causing that issue?

This could be something blocking the insides of the exhaust itself, or an issue with the alignment and installation of the exhaust itself. We would advise that you should have a local service professional take a direct look into this as we would be unable to diagnose the issue without physically inspecting your vehicle.

My mustang is a single exhaust when I get this do I have to get extra hangers since it’ll be dual for the other side or does it come with extra hangers?

This item does come with the needed hangers to attach this dual exhaust.

Is there any x or h pipes that will bolt on to this set up?

The Magnaflow Dual Cat-Back Exhaust has a single inlet designed to attach to the OEM or aftermarket Y pipe. This would not be compatible with an H or X pipe, which would require two inlets.

I have a 2002 V6 Mustang hardtop and I want to buy this exhaust but I would like to know how it sounds on the interior of the car? Mainly does it drone really bad? If I get this exhaust my set up will be BBK shorty headers and the Magnaflow Dual Cat-Back Exhaust, everything else is stock. 1 answer

This cat-back does not have drone. This cat-back with the BBK shorty headers should have a really great tone.

Will the Magnaflow Dual Cat-Back Exhaust fit with a Flowmaster High-Performance Catted Y-Pipe or will I have to keep it the same brand ? 1 answer

Yes, this catback will fit with any Y pipe with a factory style connection.

Does it have that ricey sound or is it a deep rumble through and through? I'm looking for a dual exhaust to convert my v6 and get it sounding like a v8 as much as possible. If not this, what exhaust will make it sound deep and like a V8? 2 answers

This does not provide true dual exhaust so restricted airflow, These mufflers will provide a higher pitch sound. Best bet is to use single chamber baffled mufflers with a true dual set up. This not a popular V6 option or sound.
This is a quality catback but it will make a V6 engine exhaust tone raspy, yes. Check out YouTube for audible samples of this kit. Removing factory catalytic converters and installing a set of hi-flow cats will increase power and give a deeper tone compared to stock. Getting a dual exhaust conversion kit would be best. Dual pipes with very aggressive chambered mufflers would sound perform best. My example is under user name Borr Migilicutty.

MAGNAFLOW CAT BACK SYSTEM I have a 2001 3.8L V6 mustang convertible and want to order the above system. Is it necessary to convert the rear bumper to a GT type or will the system fit with the stock bumper? Also, how loud will the sound be inside the car as I do not want a loud drone inside the cabin. 2 answers

Yes, this will fit without the bumper cover change to a GT cover. My brother just put one on his V6 mustang. Sounds great with a little rumble inside when your getting on it. But not bad. Sounds a lot better out the back than stock. Good Luck !!
This product will fit your V6 bumper, I have the same system installed on my 2002 V6. As far as sound goes it sounds great. There isn't really a drone with this system, for mine when I hit about 40 mph it does slightly but only if you hold it to a low RPM. This system is not excessively loud, but it is noticeable and sounds much better than the stock exhaust. I would buy it if I were you.

After the fact. I bought this exhaust system about a month ago and i now want to put headers on my car. Will the stock cats be bad to have with the BBK shorty headers? Is there a pipe that will fit to the headers then to this cat back exhaust? I was thinking of getting rid of the old cats and putting new ones on or getting rid of them fully. 3 answers

I would leave the cats or maybe put higher flow ones on. I have the same setup. Sound great and really make a difference with a tuner. If you remove the cats though you will lose a lot of backpressure which in turn will lose torque. It will sound even better with out but you must ask yourself whether you want hp or sound more.
Swapping out the stock headers for the BBK headers will be a quick and easy job with little to no modifications needed. Taking advantage of the time that the stock headers are removed and piping in two high flow cats, separating the catback "Y" connection, and converting to true duals would be worth the effort. Electing to go with a set of high flow cats would benefit the car with better sound, performance, and emissions compliance.
They should work with shorty headers.

is it better than flowmaster does it sound better than flowmaster ????? 3 answers

As always sound is a matter of opion however, quality is not. That is the main difference in these too. Flowmaters sound nice but they tend to deteriorate. They have a major rust problem and the black paint tends to flake off. I would choose magnaflow. I have this kit and it still looks brand new on my daily driver after 2 and a half years of owning it.
Before I picked my exhaust, I went on youtube and searched for vehicles with the exhaust I was interested in and listened to see if I liked the sound of it. I listened to a bunch of clips before deciding on mine and was happy with the decision.
As always the sound is going to be a matter of opinion. Some may feel this exhaust sounds better, others would say the flowmaster. Best thing would to research exhaust sounds on mustangs with both and see which you prefer. But remember it doesn't matter what exhaust you get, a V6 will not sound like a V8 and I have heard many V6 exhausts sound horrible for this year.

Great

Awesome sound, nice and loud rumble. Way better than stock. I have basic mechanical experience and it was pretty easy install. I did not have a lift so I had to take off the tires and shocks to get it over the axle. That was the hardest part. Everything fit and lined up perfectly.

Summer Fun

Great product. I had two clamp that where two large and had to get two smaller ones so it held the pipes tight. The clamps it came with wouldn't hold the pipes tight when they where all the way tight I could go. Other then that is sounds great not to loud and gave the car some more hours power. It like it woke my car up. Sounds like a V8 without the V8 price tag. IT get louder when you get over 2500 RPM where it sounds like a race car. LOL love it.

It took me about an hour. But, I have a lift. I had to cut and weld the hangers in the rear, so I could tuck them up to the cutouts. But now, they look and sound great.

Horrible Instructions

This exhaust came with the worst instructions ever. There is no mention of needing a lift. There is no mention of having to remove the tires AND shocks just to get the rear pipes over the wheel axel... And even when you do, the pipes are shaped in such a way that the alignment is never right. If you want to save yourself a headache of frustration do NOT spend $600 on this exhaust

Great catback

This is a great road to take if you're not planning on really pushing the hp out of your stang, it has a great rumble to it though and will really make your mustang stand out, but not a good road to take if you want performance. My install was extremely easy just because I already had my exhaust cut at the axle, but otherwise it'll be pretty time consuming on just getting the stock system out.

The Exhaust, it's OK.

Granted, the exhaust arrive pretty quickly. But installment was a hassle. First there was a missing bolt, it came with 5 bolts instead of 6. Then when trying to install the pipes to the muffler, the passenger side pipe slides right in like a glove but the driver side pipe wouldn't enter. To my dismay the pipe wasn't a full circle, but more like an oval. And I hadn't drop it or tampered with it at all. I finally managed to get the pipes in but the insulators for the passenger side wouldn't reach since the pipes keep hitting another part so it wouldn't reach at all. I follow the instructions to the letter yet end result wasn't really satisfactory having the passenger side not fit well. Then to the pay off. The sound and preformance. The sound was, average. It's not something you'll be suprised but it is more better than the OEM. "Adds the Look and Sound of a V8" Well they got one right. It does look like a V8. But sound is average. But the preformance however, that's where I noticed the diffrence. It got a bit more faster and I can tell my MayII can breathe more. Overall. I'd say this Exhaust is Ok. It's not something worth praise much but it isnt a loss either.

Deep sporty sound

Me and a friend took out the stock exhaust and put up this magnaflow, which took about 6 hours using jack stands. The difficult parts of the install were taking off the hooks from the rubber hangers and putting the new pipes in. You have to get creative and try different combinations. The driver's side was easy to put on, but the passenger side was difficult. One thing I noticed was that the pipe was rubbing on the center pipe of the car. So we adjusted the screws and pipes to prevent rubbing. The exhaust sounds really sporty and loud around 2.5-3k rpm. Overall, knowing that we had this car for 17 years, this exhaust makes a BIG difference in sound quality.

Get this one!!!

Ok so let me just go ahead and say that THIS IS THE ONE TO BUY FOR A V6. I had no other mods on my car before this and it sounds fantastic. It's not too obnoxiously loud and before I bought it I was worried it might not be loud enough but I promise yall it is just perfect and has a great deep tone with zero raspy ricey sounds. There was absolutely no fitment issues, might seem tough at first to fit the tail pipes around rear axel but you just have to get the right angle and make sure you have the right pipe on the right side. I totally noticed an increase in acceleration and the car pulls thru rpms so much better. If you just want a simple quality exhaust that sounds great and isn't totally over kill to install this is the one. On the more expensive side for bolt ons but the quality makes it worth every bit! Can't say enough good things about it!

Nice deep sound! Sounds great on start up and around 1500 rpms. Not as loud as I thought it would be but it does sound very nice. Took us about an hour to install. Could be a little louder.

Great sound

This is a great exhaust, a little pricy but worth it if you want to completely change the way your car sounds. I had the exhaust installed and had to go back in to the shop twice to get it rewelded to stop a rattling noise at low RPM's. Ever since that I've had no issues with the exhaust and am completely in love with how it sounds. P.S. It sounds great at about 3,000 RPM's

Worth it...

I bought this exhaust this spring and had it installed by an exhaust shop. My only gripe is that the right pipe did not fit even close to how it was supposed to, it pointed way up into the bumper so they had to heat the pipe and bend it a great deal to get it to point under the bumper and match up with the other side. Installation cost was a bit more spendy because of this issue but otherwise great sound great look, buy it!

The noise inside the cabin is louder than I had expected. The exhaust note is great.

I was somewhat disappointed that the kit did not include rubber exhaust hangers for the mufflers. I am having a tough time trying to find a 4 inch center to center hanger and a 3 inch center to center hanger. If you know were I can find them please let me know.
