    Dont ride without it.

    This pipe is essential. Combined with a powerbomb header, dave's mod, and some new jets get the best out of the old red drag. Sounds beastly too!

    Don't forget the jets...

    All in all a great product. Plan on jetting your carb and tuning it. I advise getting your jets if you purchase it or you'll have to wait to ride and order them. I purchased the slip on And used it on my stock pipe, it has some leaks at the connections and is a very common problem i also suggest you research this on the web before you commit, there are a few fixes if you cannot afford the full system . Too sum it up it sounds great ,gives you more pull and definitely will piss off you neighbors on stage 3....and Mounted easily , The reason I only gave it four stars in the leaks and the clamps that come with the kit don't do there job.
