I'm new to the forum but have been searching far and wide on the Internet for a little help finding an exhaust for my quad. A little info on it, it's a 2002 400ex with a 02 crf450r motor. Frame is a stock production frame other than a gusset kit. My problem is finding a pipe that will bolt on (if anybody makes a pipe for a ex that fits a crf) or what pipe will be the easiest to modify or closest fit. Thanks agian for any help

I doubt that you can find a muffler that would be bolt on application. As you stated you have a hybrid quad, so that means it uses other atv parts. You will still need to modify a muffler to accommodate the engine mount and frame.

Yes I understand that it uses part 400ex parts and part crf450 parts. I have heard of places like Baldwin and sparks making pipes to fit this setup as a direct bolt on but can't seem to find any info anywhere.

i have a few hybrid machines, and i can tell you those companies can't sell you a bolt on pipe. how would they know what angle/placement the engine is at?

stock production frame other then gussets?? its a hybrid.

not sure why you are changing exhaust,? but from the info i can get from your posts, you will need any aftermarket header from 02/03 crf and i would mod a trx450r can to it.

don't buy a slip on for the trx450 because they mount to stock header which is smaller diameter then crf headers. you need a can from a full trx450 exhaust system that is 2 inch at the joint

Yea I figured I'd have to do a lot of piecing together and mismatching header and can combos, I sent over an email to Baldwin motorsports and was told they did make a system for the 400ex/crf450 setup, but no longer make it. They told me to contact Curtis sparks, as they also made a system, so I emailed CT and am waiting back on a reply...
