Yeah might be a good way to go. The clutch will be the first thing then i'll have a closer look at the exhaust.

Ok i've pretty much decided on 2 x 2.5"

Will start it as high up as we can probably just after where the waste gate joins back in.

Then 2 x 2.5" next to each other with muffler half way down the car for each and either another resonator for each at the back or a shared larger one.

Then sell off the 3" Mandrel Bent system i currently have and all done

New clutch is pretty much arranged too so that will go in and back on the dyno again to see if we can get the 400rwkw a little eaiser...

Dunno if you've seen this but its a good design
