Increase In Performance. Bolting on a Pypes V6 True Dual Exhaust Kit to a stock 1998 to 2004 V6 will yield an increase of 15 to 25 more horsepower! This Pypes V6 True Dual Exhaust Kit includes both the off-road X-pipe and Catback needed to give your Mustang an impressive throaty V8 sound and increase in rear wheel horsepower.

Track-ready X-pipe design. Pypes designed this system with an off road x-pipe to eliminate the power hogging catalytic converter from the horsepower and torque equation. For street use, consider installing the Pypes V6 True Dual Exhaust Catted Kit.

Quality Materials. Both the off-road X-pipe and Catback are constructed from mandrel bent 2.5" 409 Stainless Steel. The X-Pipe features welded reinforcement plates for additional strength and the Dual Catback features Pypes Street-Pro 3-chamber mufflers for an aggressive throaty sound. With its 3" polished 304 Stainless Steel tips, this system not only sounds great, but it looks great too.

Application. The Pypes V6 True Dual Exhaust Kit is specifically designed to fit on any 1998 to 2004 3.8L or 3.9L V6 Mustang for more power and a more aggressive sound. Intended for off-road use. Does not include catalytic converters.

Technical Note: May require the use of O2 Sensor Extensions for proper installation. Some cutting to the flow tubes is required.

Cheese Burger or Rice Patty!? How would you best describe the sound from this exhaust? I live in Alaska where we don't have emissions laws so these are street legal. I'd like to get it but I want to know, Does this exhaust system in any way sound hallow or... "Rice'y" "tunnel'y" tin-can'y" I want to most effective exhaust for my V6 Mustang that stands out, is aggressive and not embarrassing to use as I probably wont replace it again for awhile since its about $1,000.00 to get it to Alaska. PLEASE HELP!..... THANK YOU, Kraig

  • Kraig, Me again. I read some of the reviews. From what hear that it sounds kinda ricey and that it doesn't quite fit. My suggestion would be to go with the Magnaflow Comp series. Their Straight through design NOT the rectangular muffler kind. Idk why, but the straight through sounds better. I have done so much research on exhaust because I am so particular on how I wanted my car to sound. So, Basanni is like a magnaflow but more like a 350z tone, flow master is G-- awful. I had it on mine and had to take it off. Corsa, I couldn't really find too much on it and AM doesn't sell it. Ford racing, heard it in person, sounds ricey. Magnaflow is above all. and im not saying that because I have it...well i am but its an un bias opinion. Ive heard alot of exhaust and magnaflow stuck out to me as the best sounding exhasut. (the straight through design that is). So mags with an off road X pipe would be the way to go. If your car cant fit a muffler after the axle. you can always cut the tips off, mid mount the muffler, and clamp/weld the tips back on after the axle. I say this because it sounds like there would be as much labor time getting everything on the pypes set up to fit as it would the one I recommend. Plus, you can find everything here on American Muscle. Hope this helps.

will dual v8 work on my v6 whats the difference in a v6 dual and v8 dual my 04 3.9 v6 has headers will that help me put v8 duals on it and how will it sound

  • You could install this Pypes True Dual Exhaust and bolt it directly to your shorty headers (or stock manifolds). If you wanted to use a GT catback rather than this kit, you would need to purchase the adapter mid-pipe and then you could pick the GT catback of your choice. I've attached the adapter link below so you can take a look. Give our Experts a call if you have any other questions or would like any advice on which route to choose!

would this x-pipe hook up to the pacesetter long tube headers? i was wondering this as i want to get longtube headers along with an exhaust kit all at once istead of having to install part by part or waiting really?thanx

batmanbaby Year: 2004 Model: V6

  • This true dual has a standard length mid-pipe and unfortunately, won't install properly in combination with Long Tube Headers. This exhaust kit is meant for shorty headers or stock manifolds. The long tube headers require a shorty length mid-pipe to compensate for the longer length header. Hope this helps!

    Dont get me wrong its a great sounding exhaust but pypes is the worst company my company has ever come acrossed and show no quailty in the products. We installed one on a 2001 v6 and the flanges on the H-pipe was the wrong size and way off from stock flanges, they could not seal on the manifold even with the inserts they gave you. The left tail pipe was 20 degrees off of the right side and I have hurd of these problems from other pypes customers.Over all very cheaply made system and i will never never purchase a pypes product for myself or anyone I know.

    Catless V6 Pypes

    Sounds great at idle especially when cold. Kinda loud from idle to 3 grand. Then like 3.2 it gets this kind of ricey sound except its louder than all hell and starts pulling harder. It has alot more mid end power 3-4 will be your newfound power band compared to 2-3 so basically 2-4 is where you will feel all the power. MPG also improved Would have gotten 5 stars except it doesnt have the type of flowmaster tone We all love and look for

    dont do it

    If your thinking about buying this exhaust... dont. nothing fits not even the tips. I had to add shims to the tips to get them to tighten down to the tail pipes. I had to bend the down pipes to get them to fit to the exhaust manifolds and even then with the inserts they give you they will not tighten up snug to the exhaust manifolds. Then once you finally think your done the left tip is off by a noticeable amount. So what are you actually getting? 600$ worth of parts that do not fit right and that do not even look good once your finished because of an awkward angle to one of the tail pipes. do your self a favor and keep your stock exhaust or go to a muffler shop.

    Overall, this is a good system. You need to buy two extra O2 sensors to plug up the holes in the down pipe or it will make your engine sound strange. After you work out the kinks and break in the pipes, it is a system worth buying.

    Pypes V6 Exhaust

    This exhaust really has a great sound. It is a bolt up exhaust, though we had to remove the rear wheels to get some of the pipes over the rear axle. Also, it requires cutting to remove the stock exhaust. Once installed, it sounds great. We took the rear O2 sensors and used them to plug the rear holes and just left them unconnected from the engine. That solves the weird sound, but you need a chip or an over ride for the CEL to go off.

    Unbelievable Performance

    I bought this exhaust last month and had it installed...this catback exhaust is the bomb truly what it stands for A BEAST!! Sounds excellent when driving normally but when u step on the gas u definitely get the response and sound your looking for. With the off road x-pipes it is mad loud....u can hear my Stang coming from a distance....this exhaust is a must have u can't go wrong with this exhaust performance beneath your can feel the rumble beneath you and everyone stops and stares at you!! All I can say is get this combo and you won't be sorry...
