CT sonic, Curtis Sparks,Graydon Proline,DMC or Trinity. Which one do you think will give me the most gain but with the airbox lid still on? This is for full system not slip-on or if you have other suggestions i'm listening.

 

I would look at Yoshimura rob. Just my 2 cents.

 

i would go with a DMC, thats because i have one, and i modified the airbox lid.

 

Hey rob. I thing Graydon Because i have one.i did little mods 2 my air box what i did was drill four 1 in 1/2 holes in it and cut the flabs out of the snorkel and i had a K&N airfilter with a prechargers.Runs great now i am running with out a lid going 2 try it out for the first time this week in.Almost for got My buddy has a DMC on his Raptor and i beat him by 3 to 4 bike length and i am 20 pounds heavyer then he is.

 

iuf you do airbox mods and jetting and filter and all you really cant go wrong with any of the sytsems. I would go with the one that fits your price or even looks the best. By the way buy lots of jets and experiment. You will be very upset with the pipe you get no matter which it is untill you rejet it 20 times then get it right!! Trust me

 

I myself like the Bill's Pipe. I've also had a Big Gun and a CT and the Bill's Pipe produced the best #'s on the dyno via my style of riding (sand drags). Good luck on your decision, theres lots of good pipes out there.


P.S. My second choice would probably be the DMC, one of my road dogs has one and it seems to perform very well.

 

Of all the pipes you mentioned.....I would go with the Sparks, DMC, or Trinity. The key too unlocking available power is in jetting. WHich leads me too my next suggestion...get a Dyno-Jet kit with the exhaust. The stock needles are pathetic. The DJ kit will get you roughly in the ballpark, then you can fine tune it to your machine and setup.

 

Rob660, Do you ride in wet conditions? Why do you want to keep the lid on?

BTW, there are tons of post about those pipes you mentioned. The search functionality works pretty well on this site. At least it will give you a ton of info, while you wait for others to respond.
