I got these for my 05 Suzuki boulevard c90. They are of great quality and the install was really easy. The chrome looks amazing. The Only thing that would make it better is a baffle that makes it a bit quieter. I mean... they are drag pipes so they are going to be loud. It just would be hella cool if Cobra made a baffle that actually made it quieter. So that they would look as cool as they do... but also not so loud when getn on the throttle.
It is a exhaust pipe with a full length heat shield that is attached with hose clamps. It is not a double walled exhaust system. Although you can't see it is a attached heat shield once installed, for the money, I expected more. Spend a few extra bucks and buy something like the Road Burner system.
If you are replacing a stock system and have EFI, make sure you look into a fuel management system.
Excellent pipes. Loud enough to keep the deer thinking twice about running out in the road. Brad at cobra customer service center (by phone) was excellent and very helpful. Super easy install. Couldn't be happier!
