Doug Thorley Headers

k ill get back to you on that, its dark out now and there snow all over the place, i didnt get a good look at the Y pipe so that might be why

 

ur muffler shop isn't going to touch ur y-pipe cuz u didnt get a new one. their gonna re weld the cats that are connected to ur manifold to the new headers, then that connects the y-pipe which has 2 cats, then that is connected to ur flowmaster system

 

ok sounds good then, normally i would replace the cats when doing an entire exhaust like this but given the fact that there is 4 it probably is going to save money just by using the old ones in this case.

 

yes, i wouldnt worry much bout the front set of cats blowing out cuz the short tubes are made for them. the time u wanna worry about blowing out ur cats is if u got the long tubes and kept the stock y-pipe, then u can blow out ur cats in the rear alot easier. but since u got the shorties, u will be good

 

alright thanks for the info

 

Here is how the exhaust setup is on the 1GR.
