You won't have the pre cat in your aftermarket exhaust.

Yeah I know it can just be chiselled out but the shape of the remaining piece doesn't exactly look good for flow. A piece of pipe in its place would be much better than just a gutted pre-cat. It's just a better way of doing things IMO.

A better way of doing things is to save up and buy a Full turbo back exhaust, replacing a bit of pipe at front aint gonna do much other than cost you time/money, most of the restriction is the pipe size and silencers, either take pre-cat out and leave at that or replace whole system, better still remove pre-cat for now and save for a full system :signLOL:

Took my car into powerflow in Bromley today on the recommendation that the guy there is good and could cut out pre cat and put some pipe work in its place.
Wanted to stay close to oem but make a worthwhile improvement to an otherwise standard system.
2 hours later and it was all done. Welding is top notch.
No chiselled out pre cat (which I thought was only doing half a job really), and a nice subtle cheap mod. Well happy!
