I recently purchased an '07 Dyna Low Rider. I very much want to replace the stock exhaust with an aftermarket 2 into 2. Of course I searched the posts, but one thing I have not seen is a discussion comparing the performance gains of say V&H vs. Python3, Rineharts, etc. I am used to the cars/pickups where each manufacturer posts the dyno charts for their headers, cat-back exhausts, etc.

Also, what is louder, V&H, Python3, Rineharts, .... ?

 

Jeff,

I had a 04 lowrider that I had a set of Python staggered. They were great sounding and good performing pipes. http://www.dragspecialties.com/fatbo...thon%20exhaust

check out this ling. Your best performing pipes are 2-1 on any engine.

I have rinehart 2-2 flush on my 07 lowrider and I love them, but not the price!!! Everyone will have a differant opinion. You will have to hear and see them for yourself to make the final decision like I did.
