Can anyone tell me which aftermarket exhaust is the best, but it must be fairly quiet too. I ride at the Oregon dunes and the max noise level is 93db. Which ones come with a quiet core or adjustable disc system?
THANKS

 

Yoshi is the quietest next to stock and it doesn't use disks and gives great power. The e-series, CT, Graydon, Alba, and DG have disks but those are very loud and if you take disks out you might as well go back to stock cause your loosing all your power. The Yoshi, CT, and Graydon give best mid to top power and the e-series gives great low to mid power. I don't know about the others. Hope this helps.

 

Lrd is a bit quiter then those brands have disks.

 

DUNER 2003- i would suggest looking into the fmf q pipe and power bomb header they perform very well and are very quiet.i use the same combination on my wifes 440 ex and it tested last year at florence at 93 db so it is probably real close to that on the raptor.read my posting about( taking the time to get your jetting right )to see how this pipe and header works on my 686 raptor.

 

in the feb 2002 edition of the dirt wheels mag its says in the raptor shoutout contest that the stock silencer is 92db but i think that the supertrapp ids2 is quiet and it can be tunable for sound and preformance

 

MBRP 93-96 db,with spark arrestor save .5 more.I ordered mine last week after talking with RaptorRRC,MBRP pm them they,re very helpful and they return messages.14mins
and others swear by them so that tells you performance doesn't suffer a bit.

 

I have the full Yoshi and have only heard one other piped, jetted, no lid Raptor. He had a White Bros and it wasn't much louder than my then brand new stock system. I don't know how many disks he had in it but I don't think it was over 10 or 12. The Yoshi is quiet until 5000 rpm or so, then it sounds like a very loud UZI.

 

MBRP has a good performing quiet exhaust.If noise aint an issue i like Duncan's Fat Boy 4. late,zubbeyboy

 

Duner, Check the back issues of dirt wheels for what pipe suits your needs. They had the tests and performance. Also gave decibal levels I believe. Sounds like you picked up a real nice quad. Congrats again !!!

 

I run a e-series with 12 disc. Its pretty loud.
