Catless downpipe

Fits great, hardware invludes is a lil wide to use downpipe support brackets but you can make it work using assortment of the factory bolts and nuts, sounds good, good welds and after a heat cycle or 2 the downpipe is a beautiful burnt titanium look to it

Excellent product and price

Went on with zero issues. Turned a cool gold color after heat cycling. Hope it stands the test of time because my invidia downpipe sure didn't.

Missing hardware

I discovered while I was installing I was missing 2 bolts for the pipes. Was disappointed when I had to run to Lowe’s for bolts that would fit
