Maybe I would just do the tailpipes Si.Rinehart do an exhaust system for the Challenger (but you probably knew that) I don't know if that includes headers as well or just slip ons.
I was watching a Youtube vid last nightby "Rides with 2 Indians" where he had a stage 2 (pipes and air filter and cams) fitted to his before it left the dealer from new. He then got into discussion with Lloyd'z Motor Works, who make their own cams. He then spent $3600 for their cams and a tune on their dyno and gained a little hp but lost torque numbers so he had less than a stock bike! Not a happy bunny!
The explanation was that he had decatted (iirc) with his exhaust system so little back pressure, causing his torque values to drop. The solution? Buy the Lloydz 2 into 1 system!! People who have done so are reporting 140 ish hp and 130-140 torgues.
All interesting stuff.........or not![]()
Tab performance look and sound good.
