What is the loudest exhaust you can possibly get for an f4i... slip on... is there anythign you can do to make it louder like when you take the cats off a car exhaust? thanks... i have an 01 f4i.

 

I don't know why you want the loudest exhaust there is. Loud doesn't mean sound better or more hp. If you want loud though, go with a D & D. They seem to be some of the loudest out there.

 

if i buy a d&d slip on... does it actually slip on..? i have a two brothers racing slip on there already that was there when i bought it but i dont liek the sound of it as much as a muzzy or d&d.. so is installation easy or do i need to bring it to a welder?



thanks

 

Just like the name implies -- loosen up the clamps and pull the old one off and slip the new one on. If the cans are the same diameter you won't even need to install a new hanger. I personally like the 2Bros cans -- maybe yours just needs repacking.
