I have photos of every pipe in the shootout mounted up on the bike, but this website is not letting me post that many photos. I will also have all the dyno sheets posted soon. I just need to scan them all and upload them.
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.
The dyno sheets will be listed below. We will show each pipe run layed up aginst the stock pipe with the baffle pulled. Then you can see how much better each pipe does over the stock set up.
Stock pipe - Baffle out, air box lid off and a Power commander
Peak HP - 40.96
Max Torque - 30.15
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.

97db at 3750
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.
Dasa pipe - 16 inch standard version
Peak HP - 45.6
Max Torque - 33.25
103db at 3750 RPM
The Dasa pipe is a multi stepped pipe. All Dasa pipes are hand made here in the USA and the quality really shows with perfect tig welds. The Dasa pipe does not have any heat shield mounts.
