    V8 Style And Sound. Bolting on a Pypes Street-Pro Cat-Back System to a stock 1998 to 2004 V6 will yield an instant 8 to 13 horsepower gain! It features two Street-Pro mufflers for Pypes ultimate in flow (and power gains) with an aggressive V8 sound.

    Turndown Tips. The Pypes Street-Pro Cat-Back System is designed with tips that turn down under the rear bumper, similar to those on the 1987 to 1993 GT, so no cutting or modifications are required to the stock V6 rear bumper cover.

    No Cutting or Welding Required. Unlike so many other aftermarket V6 dual exhaust kits that require cutting and welding the stock Mid Pipe, the Pypes Street-Pro Cat-Back system simply bolts right up to the stock Y-pipe for a no hassle installation

    Quality Materials. This Pypes Dual Cat-Back Exhaust is constructed from free flowing mandrel bent 2.5" 409 stainless steel piping and features Pypes Street-Pro 3-chamber mufflers for an aggressive throaty sound.

    Application. The Pypes Street-Pro Dual Cat-Back Exhaust kit is specifically designed to simply bolt-on to existing stock Y-pipe on of any 1998 to 2004 3.8L or 3.9L V6 Mustang for more power and a more aggressive sound.

        Will this exhaust need a hanger kit

        • This cat-back would come with all the required exhaust hangers to install it.

        Helpful (3)

        I've been told that I don't have enough room for dual exhaust because my fuel tank is moved over more to the passenger side not leaving much space. Any way I can get around this?? 1998 3.8l v6 gas tank is 14.7 gal.

        • The fuel tank does not change positions between the V6 and GT.

        I'm sorry I don't know very much about cars, but my catalytic converters are bad on my Mustang and I was wondering if this came with them and if there was room for o2 sensors. I'd rather buy this and install it with my dad rather than have my stock ones cut out and re welded back in.

        Can you switch the mufflers that it comes with or will it only work with the ones it has? I'm looking at SLP Loudmouth II Center/Center Bullet Style Mufflers would these work?

        • You can switch the mufflers out yes, however, if replacing with the SLP mufflers you may need to do some modifications to get everything installed properly.

        Does this require a tune afterwards for it to operate better, or would it work perfectly fine without an after-tune?

        • This product will operate just fine without a tune.

            better than stock

            the Y pipe is much to long and needed to be cut to size, brackets needed holes drilled to make them fit as needed. The exhaust sounds stock at idol. rumbles more in the car then outside( mufflers sound hollow) exhaust is up under the chassis as far as possible however it hangs somewhat lower than the stock muffler

            Sound and look good

            Definitely gives my pony a deeper tone, especially as it’s a V6, although I do have to add I have an exhaust leak so if I didnt have that, it would be even better. Looks good from the back, although does scrape occasionally on speed bumps for some odd reason, my pony isn’t lowered. Other than that, does appear to immediately oxidize a little at the tips, but that’s expected. Took about an hour at a shop. Couldn’t get it over the axle without removing the shocks.

            Would have been 5 stars

            The only problem that i had was that my mechanic had to do some minor fabrication as this did not direct fit my 1998 v6. It cost me 4 hours of labor. When i planned on two. The sound is great. I love the feel of the low sounds idling down the road. The only other problem was one tip hangs lower the the other not noticable to some but if your a car guy you notice.

            installtion went good. had it done. professional, about 3 hours. nice looking, clean. sound is ok. thought it would be alittle louder sitting still. but it is a 3.8, so compared to the stock sound. much better. getting on it the sound is much better. still not a v8 sound but for the price and look. very happy.

            Slight modification

            I had to drill new holes into the rear exhaust hanger mounts that are supplied, due to mounts are off set to the holes. Noticed the driver side pipe sticks out more than passenger side. But besides that, its a really good system and sounds good.

            Very poor fitment

            This kit did not fit my car at all (2000 V6 Convertible) and required way too many modifications to prevent it from scraping or clearing the axle (my car is stock height). From the videos I've seen this exhaust sounds great but I have no idea how other people managed to install this on their car and I wish it would have fit mine.

            Pypes dual exhaust

            Super fast shipping as usual. This product is great as long as you get it on sale. I got it for about 309. Other than that I'd go with the Macs dualexhaust for 379. But if you can get it for $309 or so it's well worth it. The y-pipe will need to be cut which is not really a big deal. The passenger side tail pipe does not have the correct Bend to it but it will fit with a little tweaking of the exhaust bracket hanger. Yes this was a very difficult install but it does fit once you get things together and work everything out but definitely use some grease inside the pipe so that you can twist them because you will be doing a lot of twisting and turning to get it adjusted. one good thing is that it comes with the dual exhaust hanger kit which is a must in order to fit this system. It does look good when finished install and adjustment. And if you want straight tips instead of the turndowns it's very simple to just cut the end off where it turns down and slip straight tips over it. As for the sound at idle it's pretty close to stock but does have a slight little Rumble and when getting on the gas or with it revving over 3 Grand it has a nice Rumble from the rear but regular driving is fairly quiet inside the cabin

            Not what I thought

            I brought this product thinking that it would make my car sound better and little louder then stock form. By no means did I think it would sound like a GT but I thought it would have a throatier sound then what it does. I'm very disappointed. The car might as well still have the stock exhaust on it.

            First I ordered it on Thurs and got it Fri morning so super fast delivery. Installation however was a huge pain the directions were useless. But, well worth it they sound really good wish they were a bit louder but they look and sound great. I'd recommend these to every v6 owner. I've been buying parts off of this site left and right to boost horsepower and these did just that.

            5 2004 V6 - ScreamingGoat43

            Great exhaust But...

            Ok so I got my exhaust in the mail thinking it will be a 1-2 hour install and no cutting like it says on the website. It took me and two other people 6 hours to install this. And there was 3 places to cut! Don't get me wrong, I love the product, it makes a great noise. It's not quite but it's not too loud. When you rev in neutral it makes a great back fire noise. When you turn the car on, it's loud, but when your in gear it makes a nice grumble. It starts to get loud when you get above 3,000 rpm. Definitely better then the stock exhaust. While installing the tail pypes, Raise the car as much as possible. Also, the hangers on the hump face the inside of the car. While taking the old exhaust off, you have to cut the old muffler off where the tail pipe and muffler meet. It's definitely worth the time and money. Oh and read the directions, good luck!!!
