I bought it asits the only one i could find with the application for the cam sensor on the inside of the pulley, its just sat there now. I remember looking at yours and thinking of trying to get something like that done.

My pulley is fine, so is DJones and AndersS2 dunno maybe a bad batch?

I think they are all the same. They just hang on I guess, Jonus used one with 1000hp and it lasted. Shame you would have thought that they would be better. The woodrough key was my main worry.

looks like something out of a meccano set!

You got any piccys of your exhaust Terrybullwon? im intrigued.

Where or what have you guys donne with the W/G, weld back in to the exhaust at origanal location?

I was thinking to take it the other side of the race cat i have as the W/G dont open unless driving so MOT wont be a problem also should help with reducing back pressure........ Just a thought. Dont want a screamer pipe as that will be the wrong side of loud for me I think, also only sounds good on WOT.

I have a home made 3" system - with 3"DP welded straight onto the original piping which is cut just past the turbo and WG. It remains 3" all the way with one back box squeezed in half way which went in after months or tinitis and scaring the **** out of pedestrians and the two original back boxes at the rear. It sounds awesome, really freed up the breathing of the engine but I would suggest you pay attention to back-pressure as this can result in valve stem problems etc.

Dont understand, you have org flange and top of DP with 3" the rest of the way with 1 box, then you still have org rear silencers still on??? is this right???

Care to expand on this?

Well after a LONG time coming i have started fabrication of the above exhaust, looks good so far!

[quattro]

Not perfect looking welding but with argoshield light i think the welds dont look that bad, penetration is 100%.

Few more

Bout 1/2 way down the car now!

Should be almost donne by this thim tomorrow not sure about the exhust hangers tho, i will definetly taking one from the middle of the gear box where the old cats used to mount. then thats where im up to.

I will be using 10mm stainless rod for the hangers not the standard 'O' type rubber cr@p, thinking more solid ones with 2x10mm holes in them, think i make my self clear, any suggestions?

I want a min of 4 mounts as the exhaust will be quite heavy with the cat and flexy bit, but i would be happyer with 5/6. any one have piccys?

When I was at Pipewerx they explained a lot of mounts stops the flexi from doing it's job especially if it's mounted too close to the flexi itself plus SS expands a lot.

Mine has 3 mounts, 1 for the back box, 1 for the middle and 1 central after the flexi and cat
