75 Diesel decatting.

Convinced as I am, that a decat will boost the power of my Synergy equipped 75CDT from 148.56bhp to 155 or more, I am embarking on a decat project.

I have ordered a Sebring back box (cat back) and have found a supplier of stainless pipe and reducers so hopefully, attacking the one piece orginal system with a hacksaw and then welding in the decat pipe, should bring about a significant improvement.

When I decatted my 45, it was noticeably more responsive, with much reduced turbo lag, and a good 'free revving' feel to it. I never got around to dyno testing it so can't say what it did to the bhp figure, but the mid range torque was superb. It felt very petrol like.

I've a feeling this will be the case with the 75 - the standard cat and system may be okay for 115 or even 130bhp, but not for 150!
