.gotta replace cat, muffler and tailpipe

[old88xj]

I gotta replace the cat conv. muffler and tailpipe. Open to any and all suggestions. Was leaning towards a Flowmaster or Dynomax muffler. Do they make better than stock cats? Or should i stay with stock replacement and focus on the muffler?

catco converter. I can't say about exhaust because I haven't used eiter brand. I have had two XJ's and find the gibson set up to run a nice low rumble and is heavy duty.

I went with the Catco from www.summitracing.com and the cat- back with Flowmaster from www.rustysoffroad.com. Both work great and you will notice a nice power difference.... especially if your cat was bad. The Flowmaster rumbles and has a great sound.
