Which exhaust?

I'm looking to get a new mandrel bent aluminised mild steel exhaust system for my GU TD28. I've had a look at Scott's Rods system which is 3" and the Beaudesert Exhausts system which is 2 3/4".

My main goal for the new exhaust is for more power and to work well with a DP chip along with having a deeper sound etc. But which exhaust should I go for? What's the difference between the sizes?

Idea anyone?

About 1/4 of an inch!!!!!!!!!.................. Well you did ask ;)

Sorry to hijack

My folks went to the Google Play Store and all they got me was this lousy Motorculture App!!!!!!!

Here is my experience with a a 3"Taipan exhaust with DPChip.
