Would be good to organise a rolling road meet to see the best gains out of all the systems

 

The one ExhaustsUK (the exhaust advertised on ebay) are selling is fitted on my car. Sounds good and I reckon its improved the midrange power. As yet to get a rolling road test. the first piccy of the car earlier in the thread was the original system and was crap, but a whole day spent at ExhaustsUK resulted in a superb exhaust. If anyone lives near Trowbridge, you are welcome to have a gander at mine. I will always try and come along to a 'meet' too.

I am happy with it.
