Exhaust shootout

[Ride1Rob]

I'm sure that this is something that you guys would like to see. This shootout includes majority of the big name exhaust systems and was performed on a KFX450R. This shootout was done by FuelATV and there is no bias for one pipe or the other.

Exhausts involved in the shootout:

Stock exhaust
Pro Circuit ($699)
Baldwin ($599.95)
Trinity ($559.99)
LRD ($574.95)
Motoworks ($549.99)
Dasa 16inch ($549)
Dasa 13inch
Sparks (Big Core) ($499.95)
HMF ($485.95)
Yoshimura ($595)
ESR ($469)

Each price came off of the home website of each manufacturer.


***From FuelATV***
I want to make a few statements here. First off do not get all caught up in the peak HP number. All dynos read different. This is why we have a base line run to see the gains made with each pipe. The dyno used is a dyno jet dyno. All of the pipes were tuned for max HP. Some pipes liked 13-1 a/f and some liked 13.8-1.

1. WILL THE AFTER MARKET EXHAUST PIPES MAKE MORE HP THEN THE STOCK EXAUST WITH THE BAFFLE PULLED OUT?
A. YES ..... All of the pipes tested ..... SO FAR.... did make more HP then the stock exhaust with the baffle pulled out. Most of the aftermarket pipes tested were VERY close. Some made a little more then others.

2. DB'S ...... All of the db testing was done at 3750 RPM. The spark arrestors were removed on the aftermarket exhausts for this test.

3. All dyno runs were done with 91 octane pump gas.



Stock pipe - Baffle out, air box lid off and a Power commander
Peak HP - 40.96
Max Torque - 30.15
95db at 3750 RPM

Pro Circuit pipe -
Peak HP - 44.61
Max Torque - 31.52
104db at 3750 RPM
The Pro Circuit pipe has mounts for the stock head pipe heat shield, but it does not have mounts for the stock mid pipe heat shield. The Pro Circuit's can is riveted together making repacking alittle more time consuming.

Baldwin Racing pipe-
Peak HP - 44.93
Max Torque - 32.18
102db at 3750 RPM
This is a REALLY nice piece. Baldwin went the extra mile incorperating alot of nice features into their pipe. The pipe has machined fittings for the canister and mid pipe making intalling it and removing it very easy. The Baldwin pipe also has a Billet canister mount, Thick head pipe flange, both the head pipe and mid pipe stock heat shields will bolt on. To top it off the end cap unbolts for easy canister repacking.

Trinity Racing pipe -
Peak HP - 45.16
Max Torque - 33.05
106db at 3750
The Trinity pipe is a multi step pipe. It has a mount for the head pipe heat shield, comes ceramic coated, and uses a trick billet clamp to hold on the canister. The pipe's end cap does unbolt for easy canister repacking.

LRD pipe - Anniversary Edition Exhaust .......OPTIONAL 1.9 end cap sleeve installed
Peak HP - 45.26
Max Torque - 33.35
102db at 3750
This exhaust features a modular billet rear end-cap design that utilizes sleeves to tune performance and sound. The Anniversary Edition pipe comes with a 1.25 inch end cap sleeve. You can buy the .875 inch sleeve or the 1.9 inch sleeve at $29.95 each from LRD. These other sleeves DO NOT COME WITH THE PIPE. This LRD pipe has a HUGE canister diameter. The LRD pipe does have mounts for the stock head pipe heat shield, but no mounts for the mid pipe heat shield. This pipe does have a billet header flange, but it is not as thick as some of the others . The pipe's end cap does unbolt for easy canister repacking.

Motoworks pipe -
Peak HP - 45.46
Max Torque - 33.05
102db at 3750
This pipe does have a billet header flange, but it is not as thick as some of the others. The head pipe does not have any steps and the diameter is about the same as the stock head pipe. Once it goes alittle ways into the mid pipe it does have a small step. The Motoworks pipe does have a riveted canister this will make repacking the canister alittle more time consuming.

Great write up!

[k4f5x0r]

fuel bought them all to test which made the most HP. he then sold all of the pipes. he took the pipe that made the highest and best run numbers and decided to sell it on his website. which is dasa.

[Ride1Rob]

Has anyone paid attention to the Pro Circuit #'s? And they want $700 plus for it :ermm: .

I added the price listed on the home site of each exhaust system up top as well.

[wolffie]

Not to take away from any company's advertising or marketing scheme, but you can seriously conclude from this shootout that...well, almost all decent aftermarket pipes yield almost the same horsepower and torque numbers. The thing that kills me, is how people CLAIM that one pipe over another is vastly superior. Really, its all in the jetting and what you can tune best for what ever engine work you have IMO. Very nice write up.

I wouldn't exactly say that the Dasa is the outright winner. Look at what their standard length pipe is making compared to all the others. The 13 inch pipe should make more hp/torque because of it's length. If you take most of those pipes and cut three inches off of them you'll see #'s very similar give or take a little either way. The Yoshi, LRD, Trinity, Motoworks, Sparks, and HMF are on par with Dasa in terms of performance. The ESR has good peak hp #'s but that exhaust falls in line with the Dasa 13inch as it's also shorter.

[crixal]

just because one pipe does good w/ one atv, doesn't mean they'll do good w/ another.

[Ride1Rob]

I would think that if a company has the resources to make competitive hp #'s with one particular bike they are capable of making those hp #'s with any bike that they put time, effort, and research into. In all of my years of ridng sportbikes, dirtbikes, and atv's if an exhaust was good on one brand it was also pretty good on another. I have yet to hear of a pipe having good hp for a particular brand and just flat out sucked a** on something else.

[Fast350ex]

Where's the earblowing TC shorty? lmao :D

[Fast350ex]

Someone should sticky this!!!!!!! :D

[crixal]

OR someone should move it to the kfx forum, lol.
