Re: Headers & exhaust
I think long tube headers are well worth it. Very good gains throughout the whole rpm range and especially high rpms. The previous owner of my car bought the DRM ceramic coated long tube headers and he put the flowmaster force II exhaust system on it. He lived in pennsylvania and he had to pass emissions so he took the cats off and put the flowmaster resonator which he convinced them were cats. This car passed emissions every year and the stickers are on my windshield to prove it. the car sounds great with no mid rpm drone that most systems have. the corsa's sound tinny, ratty and the horsepower gains are not substantial and debateable. Unfortunately you cannot get the flowmaster system any more so you would have to make choices here. Definately get long tube headers if you want to really take advantage of your ZR1's power. I would go for the best sounding system as far as cat back exhaust is concerned. You are not talking a bunch of horsepower difference here. the gain in horsepower will be with your long tube headers. get the best sounding catback and dont get caught in that 1 horsepower or 2 horsepower counting game that most manufacturers want to you believe. does it matter if your catback makes 2 horsepower less on a particular day and on a particular car anyway... it just has to sound the way you like it.
