      V8 Style and Sound. Bolting on a Pypes Street-Pro Dual Cat-Back System with Black Tips to a stock 98-04 V6 will yield you an instant 8 to 13 horsepower gain! It features two Street-Pro mufflers with black tips, providing increased flow while adding an aggressive V8 sound and a stealthy appearance.

      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 tubing and features Pypes Street-Pro 3-chamber mufflers for an aggressive throaty sound. The whole system is finished off with a set of 3" Black Powdercoated 304 Stainless Steel tips for that modern day, stealthy styling.

      Application. The Pypes Street-Pro Dual Cat-Back Exhaust with Black Tips is specifically designed to simply bolt-on to the existing stock Y-pipe on any 1998 to 2004 3.8L or 3.9L V6 Mustang.

        1 2001 V6 - DylanTerry Installation Time: Weekend

        Do Not Buy

        Terrible product. The instructions were minamal and very unclear. Hard to follow and vague, no diagrams to show how pieces were to fit together. Sound is aweful my old exhaust was louder. Would recommend true dual exhaust or straight pipes. If u love ur car do no buy.

        Easy install

        I installed these in about 2 hours, fairly easy, had to play with the pipes a little and cut the y pipe different amounts on both sides, sound is just ok, i probably should have gone with flowmasters. It would have been alot easier with a lift rather than jackstands. I really like the black tips though.

        5 1998 V6 - Stang98 Installation Time: Afternoon

        Sounds like a V8

        Very simple install, just had to cut out old exhaust, and bolt on the dual one. Startup is twice as loud and my v6 now roars like a v8. Very impressed with this new mod, thanks AM!

      Because I live in California I've been going back and forth with this exhaust, I've been trying to find a direct answer if this is legal in California I can't find one, will this be street legal in California?

      • Most cat-back exhausts should be legal. However, we always recommend checking with your state ordinances or a local shop to confirm.

      Since this hooks up to the factory y pipe with the catalytic converters, is this legal in California?

      • While this will not effect the cats on your vehicle this will not carry CARB certification. We would advise to reach out directly to your local emissions board in terms of the legality of this in your area.

      Will Flowmaster 44 series 2.5-inch mufflers work with this exhaust?

      • The Pypes Street-Pro Dual Cat-Back Exhaust with Black Tips would require modification to work with Flowmaster Mufflers. This exhaust does use a center inlet, offset outlet muffler layout.

      I have a 99 V6 will it fit and will it make my car throw out more air that it needs to or will it balance out

      • The Pypes Street-Pro Dual Cat-Back Exhaust with Black Tips will fit a 1999 V6 Mustang. This Exhaust System will add a decent amount of power without needing a tune.
