just wondering if installing an oem non highflow cat into my exhaust system
would hinder my performance once boosted...
-downpipe will be 2.75" (it's a weird size i know) rest of the exhaust will be
2.5" apexi...will a 2.5"inlet and 2.5"outlet cat clog me up, or will i be fine?
-i am only goin to run 8 pounds btw..

 

will a cat hurt performance....i plan to to weld it in tonite i need some feedback...

 

depending on what motor you will be running I see that the 2.5" exhaust will probably hinder you more then the cat.

 

....it's a d16z6, completely stock, i'm gonna run it till my b18 is ready

 

shouldn't hurt it much then.

 

k, thanks man!

 

btw it's an oem magnaflow universal cat from ebay for $64 or so...anything bad about that
cat? it's a non high flow so i shouldn't expect rasp considering my current exhaust has none
it's just obnoxious, sounds cammed at idle tho lol
