[keller45]

while it's being asked what about Fat Boys and LRDs. What do you guys think of them. They both claim a 7.2 HP increase

[ShiftFMX]

I'm gonna go with Rossier, It seems to be the more popular choice, and it looks waaay better than the dasa

[ghott]

You can't go wrong with either one!

Both are great pipes, made by two great builders.

On all dyno runs I have seen, the DASA makes a little bit better power, but its not by much.

It just comes down to looks, and who you want to give your money to :).

[honda4life72]

well who is cheaper?any sites?

I am running the LRD Pro4R full system on a 06', and it makes tons of Horsepower low, mid, and top, it doesnt sign off until your motor signs off. The Pro4 is for stock motors, and the Pro4R is for modified, and stock.

sure can. give joe a call.

[honda4life72]

it looks to me like the rossier is a more top in type pipe form the dyno sheets...anyone have dyno results with a dasa?

[ghott]

Both DASA and Rossier are great ALLOVER pipes.

Plenty of dyno graphs around..do a quick search.
