Well done video! The details on the impact of the exhaust were very interesting, for instance more sound doesn't necessarily mean more power given the loss of back pressure,
I have one on my DR 650 and it has over 13000 miles on it. Holding up very good and never even considered repacking it. So far it doesnt need it. The bike is much cooler now in the muffler area too!
What Swanky Cat failed to mention is in the manual that comes with the lexx slip on pipe it states that you need to seal your slip joint with hi-temp rtv sealant or a lead gasket. Reason being is you will have more back firing coming from your bike due to oxygen ignition. His backfiring in the video is most likely due to this or a leak at the header pipe. Klr’s should not backfire, as long as the bike is leak free and tuned correctly.
Theres one more tip that is a stage more quiet that has a 90degree angle to the ground, and is great for hunting. Lexx is a great exhaust, I ran one on my klr for years with no problems.
Another thing to consider is with the stock pipe/converter you are limited in tire width, anything beyond stock sizing rubs on the converter part of the pipe .
10% with minor bolt on things is about best you will get.....HP costs $$$$, no way around it...but how much HP does it need....torque is always better...I never heard anybody say the KLR didn't have enough HP to do what you want...if it wasn't enough, sales would tell it to stop production. HP costs...and don't need a fire breathing non Japanese brand to get it....put the ninja motor in it, or something else in a small twin...still cheaper doing that ten alternative. It does what it does and a big percentage still buy them for that. It will be around for a long time.
A little disappointed, i was interested more in the packing portion of the muffler. Im not really interested in needing to repack every 3 months on a commuter bike. Sounded ok even with the “auto tuning” of the video gear, they all come through at the same volume but different notes so none of them sound exceptionally louder than the other.
It's why I went for the internal metal baffles with my LeoVince. Install it and forget. Oh, 4 years and it still looks as new as out of the box. The quality of the stainless is beyond reproach. WHATEVER pipe I chose, it wasn't gonna involve nasty fiberglass.
