cool
thats good power in anyones terms, but can i ask what manifold you're using ? - if you're using a 2" four branch, suggest a 2 1/4" 3 piece grp 1 manifold that would give you another ten !!!!!!!
and if you were to be so bold as to go under the axle (yes you read that right) with a bespoke 2.5" system you would be looking at a few more on top of that - believe me, it works
