Just fitted one from Nippy Normans this evening.
Yes, seems a bit pricy for what it is, but can anyone really say that any of the after market exhausts that many of us fit are worth up to £5-600?
The NN piece is fine and the edges nicely finished and was a perfect fit. It arrived in the post today and it's fitted. Good job.
If you can be arsed taking the time to go to an exhaust supplier, explain what you want, faf about until they cut it and then travel home again to save a few quid, then go for it.
I just removed the exhaust and flapper valve, along with the control unit. Removed the cables from the control unit and covered the holes where the cables were with pvc tape. Replaced the unit and plugged it in again so no fault codes show up.
While I had it all off, I gave the clamps and pipe ends a good clean with emery paper and a rotary wire brush.
Used a bit of copper grease when putting it together so it comes apart a bit easier next time.
Looks a neat job and there's a nice bark out of the standard silencer now. Fronts have been de catted btw.
Recommended mod for the TC even though the flappy valve on mine was still working.
