If you get the cat back kit there is no welding required. The kits just bolt on from the stock H pipe. Four bolts is all that need to be fooled with and they are usually a *****. If your kit comes with the mufflers detached then you can use the clamps, check to see "IF" you have leaks, if so a muffler shop will weld them for 20 bucks. Flows sound great and add a X/H pipe and you are as close to being obnoxsiously loud as you can be without being a redneck.
