The benefits of the above are,quicker spool up time on the turbo/s which reduces lag,an engine that revs better (due to the non restrictions of the now missing backbox/s)and arguably better MPG and more power.
Thats exactly what i was after, thanks! The exhaust will be custom, just wasn't sure if there is anything specific i should be asking for to achieve a good sound, aside from how i want it to look.
I'll post once its fitted, it will be a twin pipe, but no M badges i promise!
