Have a look at www.longlife.co.uk is there one near you? they did me a bl00dy g00d job with a sweet big oval tailpipe for £389, custom made to fit, & mid sport option on the sound, well pleased.
I got trade quote & Kwikshit price for cat back system & they were both £290 best I could get, so for another ton, I got all stainless with a lifetime warranty 
No worries in a couple of years 'cos the 'Kwikfit shitter system' falls apart again 
Happy new thingy

Agreed. I did this and it was an extremely wise choice given that I never have to worry about it ever again.
I got a quiet one that looks the same as standard too...

To get a TC card, you could always joing Authobahn stormers. Membership gets you a TC apparently. I am thinking of doing this myself as I detect a slight blow in my system. I think that membership is around £20 and, after you have bought a few things like an exhaust, a couple of oil changes etc. you will have made your £20 back.
A general question to everyone - if you buy the parts on TC, would the Vaux garage then fit them or would you have to go elsewhere for just fitting?
Fit a standard one yourself. 1 - 2 hours.
The long-life price quoted above includes the new exhaust being built onto your car and therefore it comes fitted at no additional cost.
I got my TC by joining autobahnstormers for £20 per year. I made that back in the 1st month!
My local stealers is great about it and often extends the TC discount rate to non TC covered/listed parts with no prompting. I just walk in and he remembers the TC number off the top of his head.
