I have a 05 rap660 and i want to pipe it. which pipe is going to give it the best power increase? and then which size jets should i go up to with the pipe and a K&N?

 

LTE dual exhaust is the best exhau$t for the 660r raptor. You can buy a kit that comes with everything you need (including jets). Looney Tunes Exhaust is the most expensive but its worth the extra Bills.

 

I read about the LTE ex and its pretty damn expensive. plus i heard it takes away some low end power but adds top. But it looks sweet and I'm sure it sounds great. I was looking for something in the 400$ range. Alot of people talk about the HMF. My buddy has a White Bros. on his rappy and it beat my stock one except for top end. which one?

 

how about you do a search first ? This topic has been beat to $hit already.

 

Any exhaust is going to wake the raptor up, and everyone will have there own oppinion. I have a full Yosh system and have no complaints at all. JMO but I think its the best for the raptor except for the duals, and have rode and raced other raptors with different exhaust and can say I was at the front most of the time. I got my Yosh system at motox.com for a great price.As for jetting I just went and bought some jetts from the dealer and jetted it myself.Good luck

 

I would have to say that the hmf or the curtis sparks are a good pipe for the raptor, I have the hmf and it gave a huge diffrence.

 

Curtis Sparks, LRD, Yoshi are the best pipes. You can get LRD for around $450 complete system.

 

I just bought a full big gun limited system and I love it. It was around 450 I think at gopartsdirect.com it also comes with the quite core insert and when you take it out and put the racing core in it, it really opens it up. Befor I got the big gun I had a wb e-2 slipon and I really liked it too.

 

all I can say is LRD!! I picked mine up for $4 something, it rips hard and sounds bad-***. CT is great, curtis sparks is great. Check the lrd pro4 out though, you wont be dissapointed.. just make sure you get the air box eliminator and rejet!

 

I would have to say CT is at the top of my list followed closely by sparks and yoshi, then HMF.
