Hey i was wondering if you guys can help me out on this. I have a 03 bombardier ds650 and im looking to put on a aftermarket exhaustand was wondering which exhaust is the best sounding but has a decibel level lower then 97. My choices are a white brothers e2, pro cirtcute t4, yoshimira, big gun, ct racing, alba, hmf, trinity stage 5, ron wood, or fmf if you guys can help me with this , it will make it alote easier for me, or if you can tell me what kinds of pipes you have on your ds and how you like them.

 

i like the ct since it has disks like the alba(can tune the noise) and i hear it puts out good top hp numbers.

 

If you do a search by inserting the word "exhaust" into the search box to the upper left column you will find numerous posts on the subject.

Here is a link to just one:

Exhaust

 

im thinking of the white brothers, hmf or the alba but i want it to have the most hp and is able to be tuned for sound. does ne one kno how an hmf slip on is on a ds, or an alba pipe, or white brothers?

 

I have an HMF slip-on on my DS right now. I bought it from mrhp for about 230 ish. I really like the power increase, and for the money its one of the best. All of the other exhausts i looked at were around 500 give or take. So for the power and price im really happy with it.

 

I live in california where the DB limit is 96db. I run the FMF Powercore 4 and the HMF. I use the FMF for places I need the DB's to be low. But when I ride in places that don't have limits I remove the quiet core and it runs just as well as the HMF. So for sound restrictions i would recommend the FMF Powercore 4 and buy the quiet core. Plus the quality of the pipe is 2nd to none. And price is around $240.

 

hey guys thanks alot you guys were a big help, i was just wondering what the hmf sounds like( is it like a white brothers?) and im thinking about the brand new white brothers, the one u can replace the quiet core on it. How are the big gun pipes? Are they loud with the aftermarket quit core in them, or is the quiet series better?

 

I had an HMF slip on for the 03 and it was loud.

I met one of the district managers for Big Gun at the Extreme Expo and he told me that ALL pipes had to be sold with a quiet core to meet decible restrictions unless it specificly states that a particular pipe is a RACE version.

 

Call here http://www.hpresearch.net/and ask which one.There was a guy on who said
he liked the hmf quiet pipe. I dont know if they changed the way they are building them
but my hmf is not all that loud to me.

 

If your not going to modd the engine a bunch I would call HPR and ask them about there new tuneable pipe. A lot better overall power spread than others. If your going to do engine work then thats a whole new ball game..
