I Noticed That Scootworks Offers A Pre-muffler Bypass Kit For The Kawasaki 750 - More V-twin Music For Your Vulcan 750. Claim Is - Eliminate The Pre-mufler (sometimes Nicknamed The 'goats Belly'). - Complete With Relocated Center Stand Bumper, Improved Throttle Response And Performance, Etc. Claim Is It May Not Meed Emission Standards And Is Intended For Off-road Or Demonstation Uses Only. Has Anyone Purchased And Installed This Bypass Kit And What Are You Thoughts On It

Lots of us have done it.....I love it some do not. Check out the posts about goats belly, or de-goat and read away. There is a ton of info on this page and the yahoo vn750 page on this subject. Trust me, I did it based on the info and followed the instructions found on these sites.

I used the ScootWorks bypass. I also installed a pipe in between the bypass pipes to equalize the exhaust. I like it and it seems to have helped the performance of my bike.

I did and liked the results...
Without the cross-pipe you lose some low end torque...hardly noticable IMO unless you whack open the throttle at every launch.
Benefits are the throttle response is indeed improved...the bike revs much more freely/easily.
The noticable vibes at around 3800~4200rpm were gone, and anything over 4000rpm in 5th gave me the sense that I was flying...no vibes, no detectable working of the engine, just great response when you twisted your wrist.:smiley_th
The downside was the fact that I was battling leaks occasionally, and when the heat shields started to rattle, I chucked the whole thing for some V&H Cruzers.

I did the scootworks kit, Plus the air reed covers. IT stopped the back off poping.
I then put on a set of custom pipes. Sounds, Looks, and runs GREAT!!!

when you bought the v&h cruzers do the come with both of the headers? are they all one piece or are the headers seperate from the mufflers? ive been thinking about getting some. thanks:smiley_th

The v&h cruzers are two exhuast headers (one right side and one left side). They are one piece each all the way from exhuast port to the tip of the muffler. They also come with heat sheilds. I have them on my bike and they sound with a deep tone and good bit louder than the stock exhaust. There fit is perfect and look good. I tried jardine headers but did not like them.

The Cruzers are one piece, from header to tail, and excellently made.
The chroming is top notch, and they really look & sound great.
Worth the $320, IMHO....

Hello jm1515,
I too installed the Scootworks bypass kit. I later removed the kit and went back to my stock system with the muffler "strainers" drilled out. I did not care too much for the way the kit fit. Nothing against the product because it is a cheap alternative to custom pipes if you want the loud sound but, for me, the Scootworks kit was too loud and the fit was not perfect.

How does the Vance and Hines system compare, in loudness, deepness (throatiness), stability of fit, etc. to the Scootworks? Also, are the V&H pipes that you installed exiting on the same side, like a Harley Sportster, or are they on each side of the Vulcan750 like the stock pipes? Where are they supported other than at the heads, are there additional mounting brackets that bolt to the frame?

You know what might be a good idea would be if someone would begin manufacturing a goat's belly replacement as a one piece pipe. I mean like pipes on each side that would connect before the mufflers but with a crossover that would just fit exactly where the belly was. Then you would have a better sound and still the balancing of of the crossover. Does anyone know of such a replacement pipe for the goat's belly? Does anyone have the equipment such as a MIG welder where they can custom make such a replacment? There might be a good VN750 aftermarket for that. I know that it would be worth trying on my VN750.
Thanks,
Sam612

Hi Hizzo3,
Probably. What I meant was that three pipes could be constructed such that the finished product resembles the letter "H" and identically duplicates the dimensions and bends of the goat's belly and its connection points. That way the goat's belly could be removed and this H pipe installed in its place. Much like the Scootworks By-Pass kit does now but it would not consist of two separate pipes and all the other stuff included in that bypass kit.

Imagine a top view, looking down on the VN750. The left vertical side of the H could represent the left side of the finished "pipe" (that would replace the goat's belly) that would connect the exhaust pipe coming off the engine's cylinder to the muffler. The right side of the H, looking from the top view, could connect the right hand engine's exhaust pipe and the muffler on the right side of the Vulcan750. The horizontal line of the H represents the part (the welded crossover pipe) that goes under the frame and connects the left exhaust pipe to the right exhaust pipe. Right, like a crossover type pipe on a car like the Mustang.
Thanks,
Sam

Hi Hizzo3,
You may have missed my reply. It is on page 2 of this forum thread. Here is what I posted but perhaps an X type style of crossover would work better than the H that I describe below. Can you make such a goat's belly replacement?
Bye,

Hi sam
sorry i dont have the ability to make an x styled pipe.....somewhere i remember seeing it mentioned though of going to pepboy's and using a segment of pipe with muffler tape. i would rather use jb weld in a situation like that. i know a guy down here who made a custom cat back for my jeep. did a pretty good job of it. maybe u can find a small mom & pop muffler shop that can make custom pipes for cars, and see if the can make that lil section your missing.

I'm in the process of trying to get some custom pipes made that sweep off to one side like the jardine's join into one pipe through a muffler, then split back into 2 again. but then again i am not trying too hard, but i am asking aroung though. lemme know if ur interested in that and who knows, maybe we'll get a 4th pipe option for us vn750 owners.:smiley_th

Hi Hizzo3,
I think that I would not be interested in such a set up as you described. I'd rather have the two pipes, one on each side, all the way through. I do like the Jardine system though with both pipes on one side. Have you ever checked out this site?
http://www.cdthayer.com/cruiser.htm

CDThayer has a very good looking 2003 VN750-A19 with Jardines on it. Looks great. I really like that color scheme. Wonder if it is real loud?
Thanks,
Sam
