just scared about possible hassle and poor quality people mention about, but i'm not going big bore, mega noise huge pipes etc. just something subtle over stock and slightly deeper and noticeable, would i loose power on custom?
I have got as much chance of answering that question correctly as I have getting 6 numbers right on the lotto
Even if you have £300-£500 to spend I believe you can make the car quicker (which is what I assumed you were trying to do) by doing other things than the exhaust first
Start with Remaps, short shifters and dog bone engine mounts then uprating brakes / suspension / tyres etc etc
