I've been looking around for some new mufflers for the obvious reason that the stock mufflers suck ^_^
The V&H Straightshots SO's and the SEII SO's are the two mufflers I find most interesting. Now for the reason I started yet another muffler topic.
The legal sound limit for my sporty is somewhere from 99 to 101 dB. Does anyone know the sound production (at +/- 20 inch from exhaust) for:
- Stock mufflers
- SEII's
- V&H Straightshots
- V&H Straightshots w. quiet baffles

Thanks!

 

Wow, I really don't have an answer, but will note the following:
Sound is almost always measured at idle, under power (normal) and under full throttle. To get these results would require the sopheticated resources of the manufacture or major after-market exhaust company.

The best bet would be 1) go to a ralley and listen to the bikes you like. It is true, every bike seems to respond somewhat differently to exhaust modifications, but you will get an idea of what works--and what doesn't work--for you.

If you research this, please be sure to post your results. Thanks

 

Found out that I can actually go to the police station to get some measurements. Don't know if that's such a good idea tho ...
As for the 2 pipes... I like the looks of the SEII a bit better than the V&H, but I like the sound and the price of the V&H better than the SEII.
Problem is... I hear two different stories every time: one says SEII is legal and the V&H isn't, other says they're both not legal. -_-'
Good thing is numbers don't lie

 

If you read on the bottom of SEII's it's stamped right on there that they are not intended for on road use... or something to that effect....

At least mine were stamped....

Man I'm glad I live in the area of the country that is not so dang picky on these things... lol
