I've decided to purchase a Summit Stainless Steel Muffler (Slightly louder than stock, I like the sound) and some summit stainless tubing (the muffler shop was charging an amount, what a joke). I'm going to take it to a muffler shop but i know nothing about what to look for as far as the quality of work they do and what to request.

Should I purchase the "stainless tube clamps" myself from summit? is this how they will attach the muffler and piping once the tubing is bent? do they weld? Should I be asking them to do things a particulair way?

Please inform me so i can go in there with some knowledge and the correct things they will need to do a quality install.....

(I'm going with 5ft of tubing, this should be enough for a stock positioned exhaust exit right?) I have a 2005 fx4
