I like it, no drone....but I was surprised....I thought it would be louder. Very nice sound at 2700 rpm, and then again above 4k. It also has a meatier rumble at idle.

Here is what I did:

Removed muffler, bought 1/2"copper pipe to bend (to get the shape).

Took that to custom muffler shop, tried to get stainless....just couldn't find what I wanted, so I used the 1 1/2" "alumanized" pipe, he bent it.... I took those home, started forming new pipes to fit, plus cut holes (3/4"- 1") in ex. pipe before muffler. After that, took everything back to the muffler shop, he welded, I took everything home and installed. Cutting the holes with the dremel took a lot of "bits" and a lot of hours (6). I think if I would have made the holes in the existing pipes closer to 1 1/2", the sound would be louder, but like I said, I am happy with it.

I did get a price from a shop to do it $500+!

My cost was probably $60-$70 in parts ($20 for dremel bits....get a lot!)
