just wondering what sort of power delivery the scorpion exhaust gives. Got a series 2 with stg 4 ali af 175 kit on it 28mm dellorto with 5.3 gearing goes ok dynod at just over 10 bhp with nearly 9ft lbs. More interested in it being torquey than top speed clubman on it at the mo. Wondering if this would make any significant difference and does it need major surgery to the floor panel It pulls really well to just over 40 and will cruise at 50 + all gps looking to get it to accelerate up to that cruising speed a bit easier if that makes sense.
ps would there be a big difference in jetting

thanks in advance

If mi grey matter has not all been flushed down the pan, I think the 'Scootering' exhaust test Standard Sil S4 200cc + 30mm gave 15 some BHP a bit less with the 175, but at the expense of low rpm power/torque 'fo sho'
