Barker’s Exhaust provides a warranty on all exhaust systems for 1 year from the date of purchase to the original purchaser of the exhaust system. The warranty covers all manufacturing defects not caused by consumer damage.
Discoloration and blueing of exhaust pipes and mufflers are a natural result of tuning characteristics and not caused by a defect in manufacturing. Finishes with discoloration or rust due to inclement weather conditions and exposure to salt or chemicals are not covered.
Exhausts that are damaged by misuse, improper installation, modifications, incorrect tuning, impact, or crash damage will not be covered by the warranty. Exhausts that have incurred damage as a result of not being properly maintained or a lack of maintenance by the customer are not covered. Barker's reserves the right to determine whether the terms of this warranty have been voided. Exhaust systems that are not covered by warranty can be repaired by Barker’s Performance at the owner’s expense.

Bought for my husband install was easy and tech were easy to contact for any questions.
It was a great improvement from what it was. I haven't ridden in dirt or trails in 40 years so I was kinda expecting performance like the old 2 strokes so I am going to have to do some engine and head work and get it dyno tuned so I can get it to perform like it should.
When I whack the throttle I want to feel a little scared.
I could get a bigger bike but you have to be a giant to be comfortable on it.
Anyway I gave it 5 stars cause it did what it said it would do and it was easy enough to tune all the decell popping and the 6k rpms bogg out of it
Loved it its got a wonderful tone to it its not to loud and not to quite its just rite and gives great throttle response
