Anyone have a opinion on the Mach 1 exhaust system?(pic/data inside)

I've got a 05 WR250 and i'd really like to upgrade my full exhaust. ebay has some full YZ exhaust that will fit my bike but most of them are trashed.

I found the Mach 1 exhaust systems on ebay for $287.97USD. If their numbers are accurate this seems like viable alternative.

As usual, any thoughts, input, and comments are much appreciated.

Anyone?

Sorry man, would love to help you but I've never heard of them before. It might be like the Lexx exhaust that aren't a really big name but are really good price and are a great product. Don't know man, sorry.

I've never heard of them either.

The HP numbers look a little optimistic.

I only wish I could find a bolt on that would add a genuine 7.9 HP to any bike

I'd be rich :smirk:

If you read their assumptions you find it was not just the slip on that did it. Recommenced you do all but slip on and you will realize similar gains. You'll hafta remove pea shooter from OEM exhaust however.

Even with every free mod in the world, your never going to free up almost 8hp from a exhaust. Sounds like a waste of money to me.
