Recommended Posts

well my plan for a full decat system well went a bit wrong to day :duh: :duh:

as the template the had been used for the decat would have meant doing a bit of a cut and shut which I wouldn't want to do, it's a bit :blush: at the mo, also I want to have a full stainless system

so my Q to you is:

where did you get your decat centre section from or what did you do ????

Thanks

I got the mid pipe with resonator and the exhaust back box from a regular is200

(1) cut the flange off the back box and throw the back box away :D

(2) cut the mid pipe in 2 holding on to the piece with the resonator.

(3) weld a straight pipe from the resonator to the flange fom the back box and now you have a perfect fit altezza de-cat pipe.

I noticed an excellent gain from 1 -4k rpm and it got rid of the annoying flat spot @3500rpm.

Excellent mod for the cost.

Prolex did my cat section at the same time as the manifold - top quality kit and gave a 20rwhp increase!

http://www.exhaustuk.co.uk/home.htm another link for you.

Daza W used them, around £100 and it allows u to re-fit intime for MOT.

Gotta get mine done pretty soon too!

Same place that I used after Daz put me on to them. Very good, quick and cheap too. One of my mates also had a complete system made by these guys for his Supra and he's also a very happy bunny
