Anyone running a decat/sports cat downpipe and std centre section?
Hi all,
After a recent trip to get my car serviced, I was left with the distinct impression that getting a decat downpipe -or if I didn't mind paying more- one with a sports cat would be a good idea. I have an MY99 with a H&S backbox (otherwise standard). Anyone running a similar set up? Comments and experiences sought!
Thanks in advance.

Hi Dave, thanks for the input. I was gonna either leave the centre cat on and decat the down pipe or get a sports cat downpipe and remove the centre cat. I'd prefer to have the car remain road legal at all times.
Given that the turbo spools up 500rpm quicker with the decat downpipe, does that mean that it cuts out 500rpm earlier; does it affect the power/torque delivery at the other end of the rev range at all?

Because the downpipe has no restrictions in it,it doesnt just give better spool up time, it also allows the turbo to hold higher boost further up the rev range.
