alright guys so i just bought an 08 kawasaki kfx450r, and want to make it loud. what exhaust are yall running on your 4stroke quads to make them loud???

 

I ran a white brothers on my raptor, it sounded awsome and was very very deep. You could stand about 6 feet behind the bike and I could rev it a little and you could feel it in your chest and the air would move your shirt.

 

I haven't been to up to par on the new quads. I always loved Sparks exhaust and Rossier pipes. They sound great and great performance gains. There are much better pipes than White Brothers.

What is so much better? Please provide some supporting data.

 

I really liked the yosh slip-on that I installed on an LTZ400 for a customer one time. That thing sounded AWESOME! I also like white bros so I would go with either. Oh, If I were you I would probably get a full system while your at it.

 

I don't have any Dyno numbers in my hands, but dyno numbers have been seen as my buddy owns a big shop known around the country. Plus if you read reviews you will find better pipes than white bros. And yes go with a full system.

I had a yosh full pipe on myu 400ex and it sounded awesome (just sold the quad). Wasnt too loudl so if you are looking for loud that might not be your best bet. The white bros sounds great on the 4 strokes I think.

 

if you take the spark arrester out on the yosh pipe it sounds amazing!!!!

 

That it did.... but everywhere I rode required a spark arrestor and I didnt want to risk the fine.

 

it's so easy to change out, I would only take it out when on the track or what is called closed course competition.

 

Yosh pipes are top notch. FMF pipes aren't bad either. I ran them because I got them for free though.

 

thanks guys, i got more responses back on the damn F-150 site than i did the Kfx450 forum. Thats why i wrote here because i knew you all would come through. Thanks

 

yoshi pipes are great but also pricey, fmf is a time proven success, white bros has a very good reputation and works great, curtis sparks is also well known, dg is iffy in my book, hmf id say is more toward 4x4 performance, but those are just my opinions. Once you find a brand you want, then it comes down to the model...so once you know the brand, post another thread askin for which model or keep it goin in here.

 

curtis sparks is really good and hmf is pretty good bang 4 buck
almost all the exhausts out there will do the same thing 4 ya but i would not recommend a dg or cobra, etc exhaust

 

My vote it for the Yoshi pipe!
