Lexx MXe Slip-On Silencer With Mid-Pipe

Comments On Nov 17, 2015:Very happy so far. Install was pretty easy, a little elbow grease needed. Mated to an FMF Powerbomb header, nice fit, noticeable low-end gain. Using 34 mm race tip, sound level is very reasonable, quiet at idle, a nice throaty sound at high rpm.

Good not Great

Comments On Aug 12, 2015:Good exhaust for the price and nice to have another exhaust option on the market. Not the best sounding out there but does add a little noise with the quiet core removed, as well as a little low end power on my yz450f. Does have some rubbing issues on the tire and is very long which makes the bike look a little dated over the factory "shorty" silencer. Good for the money but if I could do it over I would probably save a little longer and go for an FMF.

Good product for the money

Comments On Jun 23, 2015:The quiet core cracked after a couple of rides, but it was replaced immediately with a new one that seems to be better quality. No issues with new core. I wish they would make a carbon fiber end cone for this pipe. Fits well, looks good, and provided a noticeable improvement in performance.

Good pipe, Great sound, WARNING: READ FOR ADVICE

Comments On Jun 19, 2015:WITHIN THIS REVIEW, I will give you advice on installation so you don't break the springs and go through the trouble of fixing them like I did. I ordered this pipe a couple of weeks ago and have been pretty impressed with it. It looks good and withstands all of my rough riding that I do. The visual aspect of it is very impressive for it being such a cheap pipe. It feels like good material and the exterior black part seems like it is a carbon tape of some sort. Anyway, I love the way it changed the look of my 400EX. The only thing that I did not like about it was the installation. The springs with anti-vibration sleeves on them can break. There are two loose ends which you will have to pull on to install the spring. Well, I was pulling on them and the loose end came completely out of the spring. I had to put the spring in a vice and hammer the loose end back into the spring. This happened to both of my springs so I'm sure it could happen to several other people. To prevent this from happening, use channel locks or something and squeeze the end of the spring to create a smaller hole. This solved my problem and will hopefully prevent anyone from having this problem. Other than those springs, the pipe is great. It sounds good, it is very very loud without the quiet insert in. Without the quiet insert, the sound will vibrate your chest quite a bit. With the quiet insert in, it vibrates the chest a little but has a nice deep grumble and with or without the insert it gives the same power added. Hopefully I could help out anyone on deciding whether or not to purchase this pipe. Very good pipe for the price.
