be wary of tune files and or chips. The best tunes are done by a local tuner. As depending where you live (above sea level, temperature, humidity etc) the pre tuend file could cause issues.

If you can get it done locally, they will be able to match it for your altitude/climate etc.

I've tried both the 2.5 and the 3" reduced to 2.5 and felt no difference between the 2. However my 3" reduced to 2.5 catted downpipe has less rasp than the full 2.5"
