mikea1988 Member 102 Member For: 16y 11m 1d Posted 04/12/12 01:07 AM Author Posted 04/12/12 01:07 AM Sweet.I can get a high flow cat for $200I have my standard exhaust under the car port.Will get them to install my new cat and old standard exhaust from cat back then go back on the dyno.
MY ROD GOT OUT Member 434 Member For: 16y 15d Posted 04/12/12 01:08 AM Posted 04/12/12 01:08 AM Only drama when putting stock system back on is u r limited for later on (I want more power but would have to push way to much boost) $450 from eBay gets u the xforce twin 2 1/2 mild steel. If u do dump u may need to port wastegate.

MY ROD GOT OUT Member 434 Member For: 16y 15d Posted 04/12/12 04:24 AM Posted 04/12/12 04:24 AM Nope, and give it a few months and u will want more
mikea1988 Member 102 Member For: 16y 11m 1d Posted 04/12/12 04:49 AM Author Posted 04/12/12 04:49 AM ok so im looking at a high flow venom cat with 3 inch inlet with 5 inch body which the exhaust shop said they will make up an adapter to run straight into my standard exhaust from there back.
