If I use a High flow cat is there a way that I could get the 02 sensor modded into it for smog purposes, or do they make any with placement for 02 sensor

 

You can get a bung welded into the exhaust pipe at any exhaust shop. It just needs to be downstream of the cat.

 

Thanks for the quick reply. I'm going to be doing my exhaust soon. I really don't want anything spectacular. What do you all think about the systems on Ebay. I just really want a good sound. Probably a header, high flow cat, and catback.

 

Note that you might need a defouler due to the high flow nature of the new cat.

True high flow will have a metalic substrate rather than ceramic and AFAIK, Moroso and Random Tech are the only major producers.

 

I found a slightly used Greddy Evo II catback system for really cheap. $175.00 WOOOOOHOOOOO!!!!!!!!!!!! Sound really good. I need a header though. Anybody got one for sale?
