Exhaust system installation

Does anyone know the approximate cost of installation for a cat back exhaust system such as the SLP loudmouth? Im planning on buying one, but i wanna know the installation cost first. I learned from my last mistake. I bought a body kit for $700 thinking that id just get the installation price later, and the installation price turned out to be like $2500 so i had to sell the kit for like $400. P.S. Dont buy an Andy's auto sport body kit, because if you want, i can have my 9 year old cousin build you a better quality one out of legos.

I would save the cash and just buy the mufflers as catbacks are a waste of money.

I agree with Rip. But aren't the Catback systems by SLP like the Loudmouth and GTX and Dynomax brand technically DIY bolt-on? :dunno:

yea i just figured out that the exhaust system is bolt on, i thought it required welding and stuff but i guess not. I'll probably be doing it myself.
