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

DustinJ

What would the clearance be on these? My 2004 v6 is lowered a bit and the kit I have on now scrapes on some large speed bumps and has caused the whole exhaust to shift and rattle because it's hitting my frame. Would these be lower than the stock exhaust or about the same?

Shaggy

Is this kit legal for street use in California?

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.

Crashin

  • 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 ?

skullreaper

  • 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?

99Metalic

  • 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 great add on to your existing stock catalytic converters. The sound is great and the only mods as far as engine wise I have is a Cold Air Intake and now these bad boys. Great V6 Waker Upper!! I found these on another site for $100 cheaper, but I will continue to get all my mustang parts from the best of the best and that's AM. THIS IS A MUST HAVE IF YOU WANT MORE SOUND, BUT DON'T WANT TO SPEND BIG BUCKS!!! You can do it yourself, I have NO mechanic experience and done it by myself.

    I was skeptical when i heard the videos but all i have to say now is wow. the sound is exactly what i was looking for. the installation was not terrible but took some time. my dad and i were working off of jacks and jack stands but we got it done. you will need to cut the old cat-back to get it off, and in my case we needed to cut the two bolts holding the system on and replace them. also i found the Vaseline helped with the removal and installation of the rubber hangers. overall very impressed.

    Amazing exhaust

    I couldn't be more please with this product. My car sounds 150% better. Took about a 3 hour install with no car lift (I used ramps). Only difficult part about putting it on was getting the new pipes around the axle. Overall a 5 star product!!!

    Great Product

    This is a great exhaust system for your V6 Mustang. I just bought my 04 Mustang and then bought this system. It fit perfect on my 3.9 V6. It sounds great and I feel a little extra power. Would highly recommend taking off the wheels like everyone else says. It gives you a little extra room. Great system and I would have to recommend it to anyone looking for a cat back for a V6 3.8 or 3.9. Thanks American Muscle and Magnaflow.

    duals

    I just got this exhaust put on my \'02 mustang.....and it rocks! The sound is 10 times better than the stock sound and it looks pretty good too. i would still recomend getting a GT bumper that has the dual exhaust inserts in it to make it look even better. Plus American Muscle shipped it to me in 3 days. i love the product and would definitely recommend it to anyone who wants to improve the sound of their V6. Thanks American Muscle!

    What An Amazing Improvement

    The other day me and two other friends decided to get this exhaust on my 01 v6. Being that one was a mechanic and he had a lift, it made everything really easy and from start to finish it only took about 2.5- 3 hours. The sound is amazing for a v6 and such an improvment from stock. It looks great too! Great investment!! Thanks American Muscle!

    Sick Sound

    This is undoubtedly the way to go if your looking to make your v6 sound more aggressive but keep in mind if u plan for performance or to finish up the job this is not the way to go. This is only the back half of your exhaust so your exhaust will still be going from 2 pipes into a y pipe then back into 2 pipes to look and sound meaner. But do not buy this if you are going to go for true dual later...waste of money but sounds WAY better than stock.

    MagnaFlow on 2000 V6

    I put this on my stang this summer. A lot of these reviews talk about how long it takes to remove the old system. Mine came of in seconds with a reciprocating saw. If you have access to one, use it. The tone to me does not sound like a GT, but I do have to pop the hood a LOT to convince peeps its just a v6. It sounds a lot like a GT at idle, but WOT is higher pitched. Overall, this system looks and sounds great.

    Simple dual exhaust

    Somewhat loud, good fit and nice rumle/gargle when downshifting. Expensive product, dont expect it to be loud if you have catted y-pipe & stock shortty headers. A lot easier then buying new x/h- pipe & a GT exhaust, but not as loud. Great product if you want something a little louder than stock. Buy a cold air intake along with it, helps It not sound like a v6
