Tors or David Platt exhaust?

That's a good rwl HP figure for that set up . I only managed to achieve 145 hp with that and 149.5 with the outlaws ! what are your torque figures ?

Sorry Nat67, got the lines mixed up on the chart (Shiraz vision!) 146.17 hp and 159.86 ft/lbs
 
Ah the Blue Max! Nice but I think Im edging towards the platt jobbers. I really like the look of the outlaws but fear they will be a trifle too lairy! Lol!

I've got the DPs and dont think they're that loud but then I haven't removed the baffles
