Superior Construction. Manufactured in the USA from T304 stainless steel tubing for strength and durability, Stainless Works mid pipes are mandrel-bent for superior airflow - so there are no kinks to rob you of power.

    Great fit and finish, installed very easily. Paired with Flowmaster Outlaws and it makes my car sound like an absolute monster. Kind of thinking of swapping the mufflers back to something quieter honestly, even for a 23 year old kid it’s almost too loud! Quick shipping and great customer service from AM!

    Great product, really changed the sounds of my flowmaster outlaws catbacks...made it LOUD!!! Only thing I would complain about is the H Pipe piece that connects to the longer pipes, wasnt flared open enough. Luckily the auto craft shop I wasn installing them at had a exhaust piping machine, capable.of flaring out the two ends

    Perfect Fit and easy install

    I bought this to get a little more sound from my exhaust and WOW! I got a lot more sound! Sounds great but not for my neighbors, lol. Actually just ordered High Flow Cats to put in this item to bring the sound below, "Give me a ticket level". Great quality and installation was easy for me as I already had the Cervini's side exhaust kit.
