These are great

June 27, 2013

I bought these because I wanted different pipes and at the time I knew nothing about Roadhouse. Now I must say their products are nothing but the best with fit and finish to be flawless. I had reason to contact them about this installation and their service was totally unbelievable. I had questions about installing this unit and talking to them made me realize I should have been purchasing their products many years earlier and far more often. If you need a good pipe look no further.

I would recommend this item to a friend.

Roadhouse 2 into 1 exhaust system.

July 22, 2011

The fit is tight. I spent the most time trying to get the front header on it fit so tight. Otherwise installation went well. It isn't loud, but the baffles are adjustable so that can change. With my bike this seems to have reduced low end torque but gained high end speed.

I would recommend this item to a friend.

Great Exhaust Setup

January 26, 2011

I was looking for a replacement for my Cobra Streetrods. After reading numerous positive reviews about the RH 2 into 1s, I decided to make the switch. This is the exhaust system I have been looking for - looks, finish, sound. The sound is a winner - low, soft, not tinny. It is low at idle and riding around town, but when I twist the throttle, it opens up. The customer service, shipping, and care from Dennis Kirk are still up to their extremely high standards. I will continue to shop with DK.

I would recommend this item to a friend.
