i am lookin into buying a hi-flow catalytic converter and headers. What size catalytic converter 2.5 or 3 inch does the stock 90 laser 2.0 n/t have on it. also are chikara headers better or should i go with pacesetter header and hi-flow cat? thanks dsmers
vas :dsm: :dsm:
 
2.25 stock exhaust, well a little smaller.

get pacesetter and port it, or punishment. chikara is backordered
 
thanks for answering. one more question if i am going to keep my exhaust setup stock other than adding a header and free-flow cat, what sized high flow cat do i want to buy that will fit up nicely with my stock exhaust tubing? :dsm:
 
stock exhaust is kinda a bastard size and its a hair smaller then 2.25 which if you ran 2.25 itll be pretty close to perfect. get 2.25 tubing and youll be good. also why keep exhaust system stock sized. you can get the full pacesetter from the motor back for lie 400 on ebay.

if not get a 2.25 ebay muffler and a descent header and test pipe and run stock tubing. stock tubing wont flow as good as its press bent not mandrel bent
