Would installing a stock exhaust of a bigger atv in place of a stock exhaust of a small atv be a practical substitution to an after market exhaust?
For example would i see any performance gains ( or losses) if i installed a stock exhaust from a 450cc atv onto my 350cc atv. After rejetting of course.
Would it not make much difference? Possibly be worst then stock because of too much flow?
For those that don't know me my name is Mickey Dunlap owner of Four Stroke Tech. In the 80's I was one of the few that made a living racing 3 wheelers and in 1983 after winning 5 races against Team Honda they started helping me out in trade for being able to use my name in there win adds. In 1984 they gave me a full ride and this was one of my last ATC 200x's that I just got last Dec. on a trip to Washington state where I grew up. I flew out there to pick up my grand fathers 1969 Ford F-100 my mom sold me. I knew of this 200x for 20 years but the guy would never sell it to me,but my mom sweet talked him into selling it back to me.
On my way back to PA. I stopped in Or. to pick up two more of my old racers from Powroll perforemance my eingine builder back then.The guy painted it Powroll's blue and white,but I just started restoring in back to the way it was when I raced it for Honda.

The Ultimate Baja 1000 Racer
By Brian McCune
Mar 22, 2007
Racing the Baja 1000 is no easy task; riding the quad by yourself the entire length of the race is pure insanity. With only half of the starters even finishing the event, it takes an ultimate quad and an ultimate rider to attempt to solo this grueling course. Richie Brown did just that and he finished the race in 39 hours. With dependability and comfort in mind, he built his Honda TRX450R into the ultimate Baja quad.
1. Maxxis Razr 2 Tires
Brown relied on the Maxxis Razr 2 for their enhanced cornering ability. The Razr 2 comes standard with a six-ply rating for maximum puncture resistance. They are made especially for demanding off-road racing like GNCC events, but work great in the desert, as well. According to GNCC champ Bill Ballance, the Razr and Razr 2 offer the best setup for the serious cross-country racer on every track and in every weather condition known to man.

2. AC Racing Nerfbars
When racing for 39 hours (or even 39 minutes), nerfbars are a must! They keep your feet from turning into hamburger meat. AC Racing is known for exceptional aftermarket parts, and these nerfbars are no exception. These nerfs are lightweight and easy to install. ($190; http://www.acracing.com or call them at 714-808-8330)
3. IMS Fuel Tank
Thinking of running the Baja 1000? Well, then fuel is something you will need plenty of! Even one extra gallon can be the difference between fueling up 10 times instead of 15 and saving precious time. The IMS fuel tank will add an extra gallon of gas while still keeping a low profile. ($225; http://www.imsproducts.com or call 800-237-9906)
4. Fasst Flex Handlebars
The Fasst bars are made to provide the rider with the best performance and comfort available. They absorb almost all vibration, which reduces rider fatigue and makes it possible to ride harder and longer (a necessity for all Baja racers). ($299; http://www.fasstco.com or call them at 562-601-8119)
5. EFM Auto Clutch
After riding 500 miles and shifting between gears over a hundred times, you can be sure all the Baja riders have wished they could just sit back and let the tranny do all the work. An EFM Auto Clutch is just what they need! Although some work is still required. The EFM clutch automatically engages and disengages itself. It also leaves the manual lever intact, so if the need arises, the rider can take control. ($500; http://www.efmautoclutch.com or hit them up at 330-947-1700)
6. Ricky Stator Baja2 Light Kit
While racing through some of the roughest terrain and weather known to man, high-powered headlights are key to keeping your eyes focused on the track ahead. Ricky Stator has been a name known in the light industry for years. The nine-inch Maxtell lights, in conjunction with the powdercoated steel protective light bar, make for a durable yet affordable setup. ($249; http://www.rickystator.com or call for yours at 760-787-0094)
7. Scotts Performance Steering Damper
Steering dampers are a must-have when riding for even a few hours, let alone 39. Scotts Steering damper reduces rider fatigue by eliminating the sudden thrusts felt when navigating rough terrain. This particular damper is also adjustable on the fly, so while you’re out riding a thousand miles it can be fine-tuned to perfection. ($400; http://www.scottsperformance.com or call 818-248-6747)
8. CV4 Radiator Hoses
Ever have a radiator hose burst? It’s not fun. CV4 Silicone Radiator Hoses are specifically designed to endure extremes. They can withstand temperatures from -76 F to +428 F, and are made to handle even the nastiest impacts. While typically overlooked on most quads, the hundred bucks can be what stand between you and the finish line in Baja. ($112; http://www.cvproducts.com or call them at 800-448-1223)
8. HMF Ironman Performance Exhaust
No one races with a stock exhaust system these days, and running the Baja 1000 is no exception. Brown turned to the Ironman series from HMF to pull every ounce of power from his TRX450R. The Ironman increases horsepower on the top end and keeps the bottom end power and torque that HMF is known for. ($340; http://www.hmfengineering.com or call them at 866-HMF-PIPE)
9. LoneStar Axle
An axle on a quad takes an insane amount of abuse, and anyone who has run a Baja race knows axles are basically butter in that kind of terrain. LoneStar axles are backed by a lifetime warranty, which speaks for the quality of the product they put out. All LoneStar axles are adjustable from two inches under stock to one inch over stock width. ($420 http://www.lsracing.com or call them at 800-457-7223)
10. Elka Shocks
Nothing is worse than having a mediocre set of shocks on a quad, so for their reliability, wide range of use, and quality, Brown turned to Elka Suspension. Every Elka shock is custom-built for each customer according to the rider’s weight, riding style, and type of terrain. This setup can take a beating and provide a much smoother ride, making a thousand-mile trek more comfortable. (Front shocks $1,395, rear shock $995; http://www.elkasuspension.com or call your local Elka dealer)
11. Adapt Graphics Kit
As the final touches go into a quad, you can’t leave out the trick graphics. For a good-looking and affordable graphics kit, Brown headed to the guys at Adapt to hook him up with their latest TRX450R kit. No matter what terrain this quad is on, it will stand out from the crowd. (Graphics kit and seat cover $150; http://www.adaptracing.com or call them at 404-704-0419)
