Suddenly MUCH LOUDER exhaust - whats up?
04/08/10 at 07:04:48

Hey guys - I was riding this morning, all fine, then went to get payroll from the accountant and all of a sudden my pipe got LOUD, really LOUD. And more louder, snappier backfiring than usual.
Although I occassionally get more backfiring when I'm low on gas, this was the pipe noise when accelerating.

Well I knew I was out of gas, so I filled up and rode the rest of the trip. Filling up has ALWAYS quieted the backfire in the past, and the pipe was never an issue.

But this time, the pipe is still insane LOUD with sharp loud backfiring - this has not happened before. I've got a Dyna pipe on, and I checked all the bolts (fine, tight).

Any ideas? I am afraid I'm going to get pulled over for NOISE, seriously! Sad

Reply #2 - 04/08/10 at 08:13:23 The baffles in the Dyna pipes, as well as the OEM muffs, have a tendency to come loose over time. You're probably hearing a more open pipe because the baffle has let go.

Reply #4 - 04/08/10 at 13:25:30 Aww man - it took FOREVER to get that darn pipe on right in the first place, now this....hmmmm. Yep, baffle sounds right - I did hear a metallic "clink" before it happened. Now I am a SCREAMING SAVAGE look out, comin thru. So, should I fix it (can it be fixed) or get a new pipe?

Performance - lower end not as good, but once I am at highway speeds it evens out. It's backfiring WAY more at shifting, like double -triple gun shot snaps instead of the usual one POOT. Grin

My coworkers were total thumbs UP when they heard me start up to leave the office last night. They loved the new Savage Sound; said I sound like a HD now.... Meanwhile, I am digging around for earplugs and full face helmet trying to be incognito as I frighten children and blow out glass windows in passing.

A friend with a Kawasaki said I might get better gas mileage now - something about not having restricted airflow?

And like I have extra $$ just lying around to get another pipe....I still havent fixed the broken turn rear signal!! Aaargh! Tongue

i have a sporty muffler with 0 baffle and i love it!!! in west palm beach, either they are 115 years old or have rap music on so it vibrates the cars next to them lol

i'm the smallest bike in our group, yet the loudest!!! even my friend's 1900 isn't as loud as the beast!!!!!

my father in law finally took a good look @ my bike and said "all that noise comes out of that little thing?"

i'm pretty sure that's a compliment lol

If you didnt rejet the first time you may have made the factory lean even worse and now with no baffle you've got a 3-fold lean condition.

Take out your compact mirror, you know, the one you check the oil with.
Get down beside the bike and inspect all the hidden sides of the muffler and pipe.
I once found on a stock muffler that two holes about 1/2 inch diameter had appeared in the underside of the muffler. They probably could have been welded up for some more miles but since I had a parts bike it was just change it out.
