Arguably the highest performing after-market exhaust on the market, the HMF Competition Series is a pure blend between optimized performance and versatility. The secret to it's power lies within the Trimax Core. This unique triangular core accepts specially designed exhaust inserts that provide the rider the ability to quickly change the power and sound according to the current riding conditions
Designed and tested for dirt bikes and ATVs.
The Competition Series distributes power evenly throughout the entire RPM range.
The Competition Series uses a mechanical core to control exhaust pulses and set power levels where they're needed.
The exhaust shell is made of T6061 Aluminum that weighs substantially less than stock.
Included with every exhaust are 3 removable inserts; the Trimax Core technology features 3 levels of power and sound, allowing you to dictate the type of power and sound you need, when you need it.
Trimax Stage 1: Uses an insert that restricts sound levels extensively yet produces industry leading power at the approved dB level.
Trimax Stage 2: Uses a different sound-altering insert that partially lowers sound levels without losing the power increase gained in Stage 3.
Trimax Stage 3: Acts as an unrestricted core producing high dB levels with industry leading power throughout the entire RPM range.
Features a black powder coated exhaust shell, stainless euro end cap, rivet bands, and the HMF team sticker for a completely upgraded look.
Packed with high-performance glass wool packing.
Includes installation instructions.

Q: Will this work with modded 2006 ltr450?
1 year 5 months ago
i have a 2006 ltr450 w/big bore kit. Will this exhaust work fine with it? Will i have to do any adjusting?
A: The HMF Competition Slip-On Exhaust should work great with your big bore 2006 Suzuki LTR450. Just be sure to correctly select the Year/Make/Model of your ATV before ordering so we can be sure to send you the correct exhaust for your ATV. Normally when installing a slip-on only minor jetting changes are needed, if any at all. If your bike is currently jetted properly you will likely not have to make any changes after installing this slip-on. I would recommend installing the exhaust and riding the bike to see how it is running then tuning your carburetor from there if necessary.
