Hi all, am currently on the look out for my perfect gsi. . . Hopefully find one soon enough!
Right questions, all comments appreciated
1. Are there any dump valves that have a flutter/resirc valve sound for a z20let? Not really into the single note sound any more!
2. What is the best exhaust system Inc. Pre+cat to get the astra vxr nurburgring kinda sound, can't remember if they come with the Remus or miltek. The not intrusive but that bite/boost noise they make, if you know what I mean, and with the pops and bangs I am assuming this is achievable as they are near on same engine
