Hi,

Will it by less restrictiv than the original one i have on my uk turbo my99 ?

Cheers

 

anyone?

 

Very marginally. It's just for sound really. If you're looking at helping air move through your car you should look at the air filter, downpipe, and midpipe first.

I've got a Group N Greencotton filter, afterburner midpipe and soon a Group N backbox from TSL. Just the midpipe made a bit of a difference but in all cases the CATs will be the bottleneck for any system.

What are you actually trying to achieve?

 

Its part of my modifications to get to 300+bhp.

So far:

green cot filter
Sti v8 tmic

Coming soon:

Vf35 turbo
Decat downpipe and centre section
Remap

My plan is to decat from the turbo down and was hoping that the prodrive backbox would not only look, sound nicer but be suitable, performance wise, to compliment a decat system??

 

It'll be fine mate and should sounds great. My mate had just the backbox on his blob STI and it was amazing.... no as nice as a Group N but hey
