Hi Nick,
I wouldn't spend money on shorty headers. Your stock exhaust manifolds are pretty efficient. Your only gain there will be cosmetic.
I've had the FLP headers on my roadster for about a year and a half now and I love them. Paired up with the Corsa Indies, they gave my car a beautiful exhaust note and about 19 rwhp/21 rwtqe.
I have been using the hi-flo cats that were supplied and did not need the '02 simulators. FLP also supplies off-road pipes which I've heard on other cars and is too loud for my taste.
I love my FLPs and have gotten many compliments on the exhaust sound.
absolutely incredible at wide open throttle and very quiet at cruising 2100RPM and below.
Check 'em out at FLP's site.
You can't beat 'em for the money. They include the full length long tube headers, an X pipe, high-flo cats, and off road pipes. The whole system completely bolts on..no welding.
You can pay more, but why?
For your driving (like mine) these are a very good product.
Best regards,
Pedro
