I would like your opinion on the Graham Goode downpipe with high flow cat.

Any pics available? (The GGR site has only one poor pic)

Is it 3 inch all the way or 2.5?

Does anyone use it at the moment with a stock ECU?

Does it replace the catted mid-pipe (before the centre section) ?


thank you very much

AFAIK it tapers from 3inch at turbo to 2.5 inch where it connects to the centre cat. If you were to get it then you would also need a cat replacement pipe to remove the centre cat to reap the full benefits. I've got the full 3 inch system with sports cat and it certainly helps spool up and torque across the range.

when i asked this question sometime ago, the general view was the quality was not of that of others around and you need the full exhaust as it will not mix and match with others

I went for the tsl sports cat and never looked back

 

thank you for your replies.

I thought that the GGR downpipe was long enough to replace the stock catted mid-pipe.

Does the TSL downpipe replace that part? is it 2.5 inch as well? I hope that I will be able to use it with my blitz nur spec cat-back.

I am also considering the catted H&S downpipe which is 475 pounds.

cheers
