Klock werks make a set of duals that they say is equal length, they bring the front pipe across the pushrod covers, and behind the rear cylinder. Been playing with the thought of making a set like that. I have read that as long as they are equal and the proper dia. they should produce good torque down low. Those short shots "except for the x-pipe" will cost you more hp and tq than a set of the true duals

baffles better but I got a very noticeable gain in mid range power which
really surprised me.
For you Young Guns I can fully understand your wanting the sound over
horsepower. If I was younger, I'm 67, I would do the same! My 2 cents.
Ha ha! I think I still consider myself a "young gun" being im my early 30's. I do want them to sound good. I absolutely love the sound that a REAL fish tail makes. I can tune pipes with dowels and a vacuum gauge. Keep the sound but dictate the backpressure.

Right on. I'll check those out. Thanks! I'm making these pipes. The price of pipes is outrageous and I don't like chrome. I want to keep it somewhat old school looking. Not trying for a bunch of fancy bends.
