Thx for the replies guys
Yeah I've done a k&n, xr8 intake, 100cell cat already and I'm dropping the car in for a tune next week, xcal custom dyno etc.
Don't want massive gains bout 280rwkw should be ok.
It's just that the inter piping is knackered and I don't like those expensive I/cooler kits because they rob front end ground clearance( and I need every mm I can get on my local dirt roads).
Maybe a std f6 might give me what I need, can't seem to find one though
Cheers
Mike
