or do they need to be welded on?

 

nope, but they supply you with enough u-clamps so you can put everythign together without welding.

 

what he said!

 

I plan on having mine weldeded, the clamps look crappy!

 

clamps suck they come loose.

 

i couldn't get the clamp off of mine. They were so tight that once i got the clamp off the pipes were crimped together. That was hard as hell to get off. I also didn't like the discoloration of the pipes, it looked like it was gold plated.

 

My clamps are like that too, with the pipes ever so slightly crimped. They are on for good.

My tips are now a dull dirty grey color.. however I got the loudmouth back in the beginnign when the tips weren't polished or anything..
