New Exhausts what size pipe??????

Afternoon Everyone

I Have the money to get a new exhaust what size pipe is going to get max power? dunno..

2 1/2 inch

2 1/4 inch

I am going for a single exsit
maybe an oval tail pipe

cheers..

2 1/4 inch will give better gains below 180bhp, above that the 2 1/2 inch is better

at the mo my pre-cat is out, de-restricted airbox and courtenay sport pannel filter, a power run showed 150bhp

keep to the 2 1/4" it will give better power, bigger is not always better 🙂

sweet ill let ya know how it goe's
