Anybody notice an exhaust echo when making right turns?

I bought AZGeek's Remus slip-on, which I'm very happy with so far, and he was a delight to do business with. I'm running with the baffle out, cause "Yee-Haw!!!" and I don't find that it is too loud. However, I took my first somewhat spirited ride since adding the exhaust, yesterday. I was making a right turn and almost shit my pants, as it sounded like a second bike was rushing up on my right side. I check my mirrors pretty frequently, and there wasn't anyone there a second ago, so I thought this person must be really coming up on my ass fast. I was mid-turn and was leaned over pretty good for me, so I didn't want to check my mirror or look behind me, just focus on looking through the corner. As I exited the turn I looked everywhere for the other bike, but there wasn't one. On left turns everything was normal, then the next hard right that asshole ran up on me again, just to disappear when I looked. Yes, it took 2 hard rights for me to realize that it was the exhaust noises bouncing off the pavement back into my ears. I never noticed this with the stock pipe, and I'm wondering if anyone else has had a similar experience. Or just make fun of me for being a slow learner. Happy Friday everyone! |

Perhaps there is an exhaust leak between the exhaust header and the new muffler?

Zitat von Richard230 im Beitrag #3 I doubt there is an exhaust leak. Everything fit together nice and tight during the install. So smells at idle, and when I ran with the baffle in it was pretty quiet. Also I don't get the echo except in harder right turns. I'm 99% sure it's just the sound bouncing back at me. Good suggestion though. |

Zitat von Chubs McFun im Beitrag #1 That happened to me a couple of times after I initially installed my Remus (baffles in) but you get used to it. Now I don't notice anything other than the farting and crackling ....

I've got a Schuberth C4 with the integrated speakers and mic. I wasn't using any feature that should have activated the mic, and once my lean angle returned to closer to 0 degrees from vertical the sound (echo) went away. I wasn't wearing ear plugs. I'm open to other theories, but the echo is my best guess. |

One thing that I have noticed during the past few years on a couple of my motorcycles is that when cornering next to a wall or concrete road divider, I hear a howling sound. At first I thought it might be a bearing going bad, but when checked everything seemed to be OK. I have finally decided that the sound is coming from the tire tread since I can't think of anything else that would cause a howling sound. As usual, good earplugs can solve a lot of these strange noises.

The noise level from a sound/noise source reflecting from a rigid (non-absorbing) wall will be 3db higher than the source alone. Why the turn would significantly change the travel distance of the reflected noise (assuming the road is the reflecting surface) is beyond me.
