for the downpipe on the ams turbo back do u reuse the stock gasket/flange on the o2 housing or do u remove it? Also im glad to finally meet a company who actually has there **** together. It was painless and a pleasure purchasing my exhaust system from you guys (even if u did forget 3 bolts and a flange and then sent it to my g/fs house instead of mine) I just wanted to thank you guys for the great service and am looking forward to doing business with you again.

 

one more thing should i wrap the downpipe in some kind of heat shield wrap crap to prevent the burning of the front diff. fluids since i have an 05? thanks
