klr low buck mod or 2 bros pipe klr650

Hey guys, I came across a smoking deal on a used 2bros exhaust pipe for 100$$$. The shop tells me it is loud. basically it's a racing pipe I guess. I don't want to rejet the carb, so basically I just want a little deeper sound out of it. The air is thin here in Colorado anyway, so do you guys think I should go with the low buck mod and keep the original pipe on??? is this a better option if I definitely don't want to mess with the carb??? Is this a "if it aint broke, don't fix it, type of issue........

Unfortunately, these exhaust threads usually turn into one of these when the subject of noise abatement inevitably arises.

I may be wrong, but I believe the 2Bros exhaust is, as your shop described, a very loud muffler compared to others that are available that seem to strike more of a balance between peformance/weight loss/appearance vs. decibels. It seems a lot of people on here run aftermarket exhausts but don't want a lot of noise.

Since you asked, and especially if you're content with the way the thing runs now, I'd vote for the low-buck exhaust mod augmented with the .22 mod/slide drill mod. I peformed them on mine and think they compliment each other nicely.

It sounds like you're after "deepening the tone" a little and the low-buck mod will do that with very little expense to you.

Were I you, I would pass on the good deal on the 2Bros pipe and do the other mods and see if you like the results. My Humble Opinion Only.

The downside to, "LOUD PIPES SAVE LIVES!"


Seriously, dynamometer charts I've seen with aftermarket exhausts show but marginal gains, and at some rpm regimes, LESS power and torque than the OEM systems they replace (essentially otherwise stock engines). YMMV, and if you can convince yourself you're going fast because you're making lots of noise, what can I say?
