I honestly don't think you can go far wrong with the AE 2035 pipe and manifold buddy. EFRA legal as well. 'Tis a good all rounder in my opinion
Done about 15-20 tanks on my engine since i've got it. Very impressed. P4 plug and AE pipe and manifold. Getting a steady 8mins 30secs already. Still running rich on the bottom though and plently of smoke through the rev range. Did have a problem with it feeling very 'flat' half way through the power curve. Found that out to be a lean LSN...some how about 0.5 of a turn to lean...woops lol
