I am looking to upgrade the standard system fitted to the car as it is used for sprinting and hillclimbs. When the season finishes, possibly use it for a couple of easy tarmac stages.Has anyone recently fitted such a system and encountered any problems. Group A downpipe + Mid. sec. + Group N B.box.

 

We fitted a group N Mongoose system to my mates STi6. Its a nice fitting system and comes with two downpipe, quick release, downpipes. I think it was around £350, although I, may be wrong on that.
