So then, my car's apparently still not running 100% after discovering that it was only making 130bhp-ish on Awesome's rollers. Might be a blocked cat.
I was saving up for a BCS downpipe sports cat but haven't got the funds together yet, and I'd rather get my car running right. What are people's views on an unbranded sports cat down pipe, or welding a universal sports cat into the OEM downpipe?
