Breath deeply then exhale...4 stroke pipe combo on sale

What is the best upgrade to your 4 stroke mid bike?

How about a proven combination that provides powerful results...

Genesis Autoworks, inc of Elk Grove has a combo that is guaranteed to boost the output of you 4 stroke x7 or rx12.

WHY
The exhaust port on your engine currently dumps into a 2 stroke pipe on the x7...this is all wrong.

On your 70cc-110cc rx12 the exhaust bottle necks from a 22mm exhaust port to a puny pipe that bends around the frame like spaghetti...then into a restrictive stinger...

The Solution
How about tried and true Stainless Steel CHM 22mm pipe and a K&N style woven cotton element Air Filter... $210.00 (x7 4 stroke) shipped within the 48 continental states. Call for details on the RX 12 application (requires slight mods)...All pipes are in stock ready to ship. Made in the USA! I guarantee that you will feel a performance jump or your money back!!!

The Independent pipe review
All I can say about this pipe is Wow! After trying this exhaust, I promptly put my WB Race pipe up for sale. This is the type of power that appeals to me. This is an absolute brutal pipe. It has a tremendous hit down low and a very impressive hit again in the mid range. The best way to describe the low to mid transition is like dropping a gear in your car and punching the accelerator hard, setting you back in your seat. This pipe has the most over-rev of any pipe I have ever experienced for the CRF with the exception of the Pro-Circuit pipe with the top end cap installed. This system is phenomenal from the crack of the throttle, 'til you're bouncing off the rev limiter.

The pipe is the king of fast acceleration and 10ft. tall rooster tails. It handles short shifts without effort; I can easily do 3rd gear MX starts with this pipe. Despite the neck snapping performance, it does have a few shortcomings. The header doesn't have mounts to use your header guard, and the system is not the lightest in the test, but also not the heaviest pipe out there. The construction is on par with most all of the pipes out there, the pipe has a nice kind of dark gun metal grey color to it. Some may like it some may not, just like the WB race pipe.

This pipe is up there with the Pro-Circuit with decibels. CHM offers a "decibel box" which lowers the dB rating to a quiet 96 dB for those in California or those who ride close to populated areas. This pipe would be outstanding for MX but might be a little intimidating for moderate trail riders. If you ride aggressively, you must try this pipe - it begs to be ridden hard.

Last Corner
All of these pipes are outstanding and I would be happy to be riding with any of them on my bike. You can't go wrong with any of these pipes.

• For the value minded rider looking for the best bang for the buck, the HMF is the obvious choice. The price/performance combination, along with the durable and nice looking powder coated finish, makes this pipe a winner.
• For the Aggressive MXer, trail rider, and horsepower freaks like me - the CHM takes the checkered flag.
• For the moderate to aggressive MX and trail riders, and riders going for the best-looking system, the Big Gun blows 'em away.
• For the rider looking for the lightest and most versatile pipe the Pro-Circuit takes it, it has more than enough power for beginners… and experts.

The first 5 combos will receive a FREE pair of super stick race grips...Red, Blue, or Black(from local Scotts competitor)

What are the slight mods for it to fit the rx12

You need to bend the pipe 1-2inches in towards the frame and them mount to subframe. We do this mod for $30...

Looking for anyone from michigan to try new products. i have 2006 x-12 looking for as many upgrades as possible. pm me if you need some testing done on new products/

let us know the resalts of the pipe on the Imortal and I will consider getting one off you some time later when I got the cash. only prob is im in Australia so is shipping expensive?

I got this pipe Combo from these guys, looks nice sounds nice , But EXTREEEEMLY LOUD, 97 Db = Deicible. Almost as loud as a Harley Davidson. only thing the pipe didnt mount correctly, so i had to take to a Muffler shop and had them do about 3 small bends and had it bended up at the muffler end to face upward they even welded a small piece to bolt the muffler end to the rear of thr frame. this pipe is so loud i have to use ear plugs to ride my bike. Im not exactly sure how much HP i gained out of this pipe, but i really felt a big difference in the bottom end. i had to richin my carb one notch up with this kit. And the air filter look pretty cool. K&N Stlye filter black cotton and chrome cap.

I talked to Sid he is a cool guy. fast shipping !! im going to be buying another pipe combo from these guys. i have three x7 4stroke. im going to try a different set up on my 3rd 4stroke.

And if you have grumpy old neighbors, i wouldnt rev the motor with this pipe in your garage just to hear how it sounds. i got hated on and they called the cops, all they said to me was "keep it down" ....

Good Pipe
