Default 2-1 Exhaust

I'm gearing up to install the Hammer 1275 kit on my Iron. As part of the conversion I want to install a 2-1 exhaust. I'm currently running 3" Rush slip-ons. I know they do great in the tests that Hammer did with exhaust systems, but I prefer a 2-1 system.

The only stipulation is that I want a system that isn't obnoxiously loud. My 3" Rush exhaust with 1.75" baffles is plenty loud for my taste and probably my neighbors as well. Give me recommendations.

I have Supertrap supermeg 2 into 1 on my bike. I'm running 20 disc with a competition cover and its not too loud. A lot quitter than the 1.75 Rush slip ons I had. They are a good performer too.

I'm using a Kerker / Supertrapp 2 into 1 that is very quiet at idle but wakes up as the revs come up. It is very similar to a pipe that Vance and Hines sells or sold.
I like it a lot but it does kind of look like something of a sport bike.

On my Glide I have a Supermeg, which is tunable for noise or performance. As I use it for touring I didn't want it to be too loud and it gives excellent performance, while also being civilised. I still have the stock system on my Sporty, but come the day I change it will be for a SuperTrapp. In the case of my Glide a surprise is just how much smoother running it is with the Supermeg, which is a real bonus. If it does the same with a Sporty it should be a joy to ride!

I've got Thunder Headers 2-1. On decal they can sound like thunder, but pretty reasonable normally.

Since you've been to Hammer's website no doubt, might want to check out his exhaust reviews.

http://hammerperf.com/ttxlexhaust.shtml

According to them, the Patriot Defender was the best performer and was used as their benchmark. As 2-1's go, it probably one of the best looking too IMO. However, lean angle/clearance might be a problem with them. Doesn't really matter though - they stopped making them. Bummer.

Close second - per Hammer's test results - Supertrapp's Supermegs



As can be seen in Hammer's dyno results - the 20 disc comp end cap setup is equal, if not better than the Patriot Defender all the way up to 6.5k rpm. I'd say for practical purposes, it's a better performer. Perhaps for some, a downside may be that they are a pretty quiet pipe. Only other issue are looks and perhaps lean angle/clearance. Looks are in the eye of the beholder. You'd have to ask those that have them installed about clearance issues.

Maybe another possibility, the D&D Bobcat. I've never been a big fan of it's looks, but to others it might be eye candy. Seems to be a decent performer. Also, from the clips I've watched, they don't seem to be too loud.

Just poking around and looking at the dyno results on Hammer's website, one might find that 2-1's aren't necessarily a must. For example, a pipe that I've often seen maligned as a poor performer is V&H Short Shots. Here's their comparison with the Patriot Defender...



The baffled version seems to equal - if not better - the Patriot all the way up to 6K+ rpm. For everyday riding - does that separation above 6K+ matter? If you want to win the numbers game on a piece of paper, then the separation past 6K+ might be a bummer. For practical purpose though... Meh.

Probably a more valid criticism of the Short Shots is the prevalence. For a while it seemed that's all you saw. But then again, there was probably a reason for that. To many they look and sound good.

I wonder why you'd want to get rid of the Rush's. They look to be good performers. You just want a different look?

I’ve been looking at Hammer’s results as well. I do like the Rush pipes, but I like the look of the 2-1 and want something different. Something that I don’t see all the time and I don’t mind it being a little quieter than most. I’ve never been a fan of loud pipes. Seems that the Supertrapp would be a good choice. I appreciate all the input so far.

Well you don't see these every day and I would say that it is quieter than everything out there short of a choked off Supertrapp megaphone. It wasn't tested on the Hammer site but A local guy told me that it makes great mid power.

Looks awesome. Looking at the site, it looks like it isn’t available for my 2014.
