Way to small

This exhaust said it is an exact fit for my 2009 klx250sf and it is now even close to fitting it. Very bad do not trust the website.

Wrong size plus stock clamp doesn’t work. Had to cutt flange off of stock exhaust and adapt so works

Fast shipping, excellent price. High quality slip.

Installation took 30 minutes on a 2015 XR650L , fit was perfect, bike had been jetted prior to Big Gun installation, what a difference in runnability, especially in the lower end and mid range. Would definitely buy again.

Puts thump in big thumper

Bought this for my xr 650l, after jetting the bike it’s exactly how I like it. The big gun exhaust sounds awesome, may be too loud for some, but I love it.

Tricky install

I ordered this for my klx 250. Let me start by saying that it was difficult to install. I had to make my own brackets and ghetto rig the slip section. That being said the backfires and obnoxious sound I can’t get enough of is
perfect. If you can go to your local auto store and don’t mind creating your own brackets this exhaust is well worth it.

One problem

Everything is great but when connecting the muffler to the pipe they were the same size.....had to get a connector to make everything work. Looks great & sounds great.

Too Loud for Me

I knew Big Guns were loud, but was hoping with the accessory quiet core it would tone it down a bit. It didn't. This pipe is loud. Also, I was expecting it to be black with a black tip. It was silver, with a red tip. My KLR 650 is blacked out, so that was disappointing. Last complaint is the clamp they included wasn't big enough. I fought for an hour to get enough thread to show to start the clinching nut and just couldn't get enough thread to poke through. Lame.

A: That is a great exhaust, unfortunately I can not give you an accurate answer as it will vary from set up to set up. You might be able to contact the manufacturer and inquire if they have those stats.

A: 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.
