hi all i have owned a 98 terzo for about 6 months but it has this scorpion exhaust with a 4"" back box which sounds great but after a while gets to you. also dont know if this is gonna be causing performance loss. has anyone had one of these systems who can through some light on it.
ps think its still got the cat installed cheers rich.

 

had a scorpion exhaust on my P1. good on performance but the noise got to me a bit especially with no cats. changed to a 3" revolution system which is one of the quieter systems.
