Newbe here. So here I go...I have a 04 RG with 95" KB pistons, Complete head work, S&S570 w/Gear drive, Fueling lifters and oil pump, Rivera pro-clutch, Wild thing 57mm TB, Zipper AF, True dual Rineharts = 105hp -101tq. So Iam thinking of getting rid of the rineharts and installing a 2-into-1 thunderheader or the new Vance and Hines Pro pipe Hi-Output 2-into-1 pipe. I am also thinking of installing a Thundermax w/autotune setup. Any info would be helpful. Thanks

 

Not an expert but I'm running thunderheader on my 107 gave me a nice boost over my duals. Heard the high output pipe is big built motors like 113's and above. I did see the high output one at a bike show and it did look nice. V&h does have good fit and finish

 

They both make great numbers and both have tier own sound. The HO Pro Pipe IS very nice. The Thunder Header is what it is as far as fit and chrome and crappy heat shields but they do work!

 

I had the HO V & H pipe, and got an exhaust leak after one month. I have switched to a Thunderheader. The V&H is designed by a outer division of the company, and you will have to deal with them and not V&H if you have any issues. I know...

 

Out of those two V&H. I still like the D&D fatcat better than both of them.

 

I would go with the Thunder header if I had to choose between the two. Are those the only two pipes you are interested in?

 

If thats your two choices go with the Thunder Header.I have a ProPipe HO it is very very hot.They do not have heat shields for it either.I wrapped mine it did help greatly.But the pipe is for big blocks,being you only have a 95" i think the pipe would be overkill for your motor.

 

Consider the D&D Fatcat. It is a high quality pipe with excellent workmanship.

 

u cant beat the thunder header for performance

 

Actually you can, with either the Fat Cat, Road Rage or Pro Pipe HO.

I like Thunderheaders but they ARE NOT the best performers ANYMORE!
