Re: opinions on supersprint
I`ve got a 145QV with full Supersprint system and with de-cat pipe. It is fully stainless steel and has lifetime warranty etc, etc... Isn`t too noisy at all, certainly not like the neds with their Novas and Escorts etc... In fact I had the K&N filter on before the exhaust and with the K&N the engine noise is louder than the exhaust.
I recently sent the ECU away to Autodelta for a re-map. If you`ve got the bucks I`d fully recommend you go for it. To give you an idea of performance I was at the Crail Thrash on Sunday and was consistently running low 15`s for the 1/4 mile - it was pretty wet and greasy aswell. Best time was 14.7s -keeping up with a Clio Cup and Golf VR6.
The re-map doesn`t make a massive difference, however, it is certainly noticeable and makes things smoother.
