$2,100 for the entire kit. All you need is the 4-hole primary flange to match up to your headers. Too many variables with your engine, body cut outs ect.
When your fitting your side pipes, just wrap them in a towel and blue painters tape. If you do get a scratch, stainless is very easy to polish them out.
Here's our muffler. Point the louvers away from the engine for better flow, or towards the engine for a bit less noise. Look how restrictive one of the manufactures muffler's are.
