Did anyone ever hear of these guys? i was looking on there website and they make some crazy dual exhausts.
Looney Tuned exhaust

 

There have been some discussions before on the exhaust. Do a search on this and see what you can find. I love the way the exhaust looks but I hav'nt heard much on the perfromance side of it. Me personally would think they could give more peak hp but they would take away from your low and midrange. They may would work well on a bigger bore engine like the 727's or 770's. My brother races round dirt tracks; open headers vs. running the exhaust into each other together; the exhaust running together seems to give better lowend out of the curves and the open headers give more on the straights so I would think the same principle would apply to this(maybe its hard to say). The back pressure of the pipes can play a major roll in how the power is delivered and were the power is delivered. Its kind of a give and take thing but I am no expert on this subject. If anyone has had any comparisons between the LT DUALS vs. any other pipes I would be interested in hearing how they compare too. Slim

 

With 2 separate end cans....more power in theory can be had with the right design. I would go with around stock size headpipes too keep low rpm velocity up....the separate cans should flow like a **** on top end. Someone will have them for comparism soon I figure. Won't be me laying out 7 bills on an unproven design.

 

I'd buy em up if I could get an Oregon dunes legal pipe out of it. I'd think 2 mufflers could be quieter while still flowing adequately...???? If it does as well as my Sparks pipe but quieter it would be worth the price.

 

it should be alot quieter than a sparks pipe!

 

is a sparks pipe really loud

i wanna wake up my mother and half of PA with a pipe!! i want it to be like a harley pipe
