I'm interested in adding a muffler to my bike and would like your opinions.  I would like a direct replacement muffler so I'm considering the Jardine, Supertrapp or Mac.  What do you guys recommend?  Which one is cheaper???  Which one gives a good sound, not too overbearing.  I've heard the sound clips and I seem to like both Jardine and Supertrapp, so looking for your personal thoughts.  Thanks in advance!

Supertrapp, expected soon
Jardine slash cut, two on hand ready to ship $177

I have a MAC and it passes the wife test...  barely.

I bought my bike used with a jardine in place. It was a little too loud for me so I found a harley dyna drop off and like it much better. The jardine when I took it off was open all the way thru, unbaffled. I don't know if the PO modified it but the harley dyna is baffled but not as restrictive as a stock muffler. I think you need a certain amount of backpressure to run good. Anyway I listed the jardine in marketplace, looks nice but it's loud.

Do you like the sound of your MAC?  Is it a deep/tough sound or just a bit louder than original???

I only have experience with the Supertrapp. It's loud compared to stock, but I hear H/D's all the time that are louder. It's not obnoxious & can be ridden so it's quiet enough to roll thru a Hospital Zone & not be afraid of disturbing the sick folks. All it takes is gentle action on the throttle. Nail it & it growls & goes. Quickly slowing, dropping thru the gears, it makes the grumbling, rumbling sounds of a hot rod, with the occasional backfire, none are shotgun type, just rumbling & occasional popping. I think it sounds very nice. I dont get people glaring at me at red lights, like I would expect if it was just a nasty sounding thing.


Ohh yea, I am running 14 disks on the TRapp.

I also have a supertrapp and I highly recommend it. You dont even have to rejet it but to reach its full power potential you eventually will probably want to. Until then just run with 4 to 6 discs and you can run 8 to 14 after you rejet for more power. Check out this link to read about it and check out the dyno graphs to see how the jardine compares. http://www.thumperpage.com/articles/ls650exh.html  And if you decide its not loud enough you just run the open end cap http://www.denniskirk.com/jsp/product_catalog/Product.jsp?skuId=&store=Main&c...

That is actually true about any exhaust.  Back in '69 I had my VW shipped from Greece to New Orleans, picked it up to drive back to Warner Robins GA.  One small problem, I had busted the muffler off my extractor exhaust.  A bit loud.  Got lost leaving New Orleans, ended up in a park, cop pulls me over, I shut off the engine.....

"License and registration please.  Do you know why I pulled you over?"

{I'm running an open exhaust rattling windows in the next county.  You think I'm stupid?  Of course I know!}  "No officer."

He then said something about running a stop sign which rocked me "Say what?  What stop sign?  Where?"  Short story, he lets me go with a warning, goes back and sits in his car.  Behind me.  With my open exhaust pointed at him.  He is waiting for me to leave.   Start the car without giving it any gas.  Idling.   pop pop pop....  First gear, feather the clutch, 1/10 throttle, pop pop pop, shift to second, pop pop pop.....  Yeah, you can be quiet if you try.

I went to the harley shop and purchased an exhaust for a road king for $25 and it sounds nice!  it's a deep soft sound until you get on the throttle and it opens up and sounds real good.  it didn't mount up properly but i made it work and I love it!!!
