That said i feel like my VWR is getting all the air i need in but at high revs it feels strangled which i think is exhaust.Is there any benefit to fitting a decent down pipe and 600 cat on a stg 1 lump or is the std downpipe ok at say about 310bhp ?
I know stg2+ is really the way to go but i think i would rather refine what i have now and go for longevity than all out power and associated high mileage and wear problems.
If i want to frighten myself i will just take the Laverda
