New Exhaust, rustys?

I am looking to replace my muffler, tailpipe, intake and possibly put in a throttle body spacer. There is a rustys kit that includes a flowmaster muffler, new tailpipe, "rustys air tube", throttle body spacer, and a K&N cone filter for 255$. I was wondering if this is worth the price or is this kit a piece of crap. If any parts of this kit do work well what are they? Are there any other companies or places that you would suggest getting my exhaust or intake from? Would it be worth it to get the larger K&N filter, 9in compaired to 4.5in? Lastly, I could get the flowmaster series 40 or 50 muffler, which one sounds better, btw I do care if it is quiet or not. Thankyou for any help. -jack

A couple minutes on the search and bang, answers :wave:

I have that package on my XJ with the Flow 50. I like it, no complants. I wish I had gotten the 40, just cause Im a kid and love the loud exhaust, but the 50 works, and I still like the sound. I still have hearing to damage, so I might as well start when Im kinda young.
