| At last we got back on the dyno today and tested Adam's Mini Mania exhaust 421 manifold, unfortunatley I haven't got the time to do all the comparisons but I can tell you that it out performed the 4-1 at rpm in theory it shouldn't off.
It made 139bhp at 6021 and 124 ft lb at 5089 (4-1 manifold made 135.2 at 6210 and 121ft lb at 5667)this was with the DNA exhaust sytem and a STOCK air filter, we actually lost horsepower with no panel filter in the stock housing and with no housing and airfilter.
This news flash is over for now and when I get 5 mins I'll give you more facts and figures.
