Im now the proud owner of a 2003 astra gsi turbo! and im after some advice please.
Whats the best air filter to fit?
Whats the best exhaust to fit? (i dont want a loud 1 just 1 for performance and that gives off a nice burble and deep sounding).
Whats the best dump valve to fit? (i heard on here the bailey can cause running probs).
i also wanna get a turbo timer - which 1 is best?
And any other mods i can do before i start spending mega bucks££££ ??
