I'm looking at the trackday system shortly. On their website there are a couple of videos

If your below 400bhp then 2.5" is sufficient and imho has a better exhaust note too..

Agreed. I'm running a cobra 2.5" system on my 340bhp car and sounds great with windows down in summer but quiet on motorway cruising.

I've heard the 2.5" is better Trouble is car was mapped with a 3" I've swapped it for another 3" with no problems if I go to a 2.5 I'll have to get a map tweak plus a downpipe and is it gonna be worth the extra cash over the 3"?
