exhaust performance charts
I am looking into a new exhaust system for my 2007Dyna Wide Glide. There are many threads on noise and sound but I cant find any on performance with performance charts and curves.
My #1 factor is performance. I want low end torque. I do lug the engine too much.
I am under the impression that 2 into 1 exhausts are generally better performers for low end.
Anyone know where I can find any comparison charts for exhaust performance?

If I am reading this correctly. the torque is increased from 75.5 to 83.4 in the 4000 rpm range.

RE: exhaust performance charts
Yeah, it's driving me nuts that it's so hard to get an deffinite answer are this... Stever at GMR recommeded D & D fatcats and Bassani Road Rage 2 into 1. I like the looks of the Bassani better... chock out the SuperTrapp 2:1 SuperMegs also claim to be the best for performance... also quite... don't know what I think about that. Their catalogue says they have the #s to prove it... but they ain't inthe catalogue (correct me if I'm wronge). I like their looks too, would like a little (read allot) of sound though.
I would stick to tunable exhausts with 02 senors. My guess is that they are all about the same. I'm sure some will work better with a particular engine build than others... but given they have not all been tested on your particular build... who knows... a stock engine compare might be helpfull, but we know some exhausts will work better with a larger cc engine than others... so if you're makin' your engine larger than stock... who knows...
I know some guys love LMR... I've been steered away from them with quality control stories, bad attitude from the company, I've heard they are a real bitch to tune...
