Now I know most people get 2 1/2 exhausts and that is supposed to be optimum however just glancing at the dev packs, is this different for BA's cause the 3 inch exhaust and cat gives an extra 4rwkw over 2 1/2. I know the 4kw is rather trivial but i'm just curious.

edited: also, does anyone know what the Hi-Volume Intake Air-Flow Conversion kit consists of priced at $160? im thinking its like the xr6t intake or something.

i think 3 inch isnt really needed unless your planning on running a turbo/supercharged system or if its a V8 single pipe. They are jus trying to get more money out of u thats all

yeh, I thought as much.

well the 3" pipe will give a higher rpm peak kw figure!

2.5" is a really good all round size for most ppl

jmm like to boost thier peak rwkw figures
