New to the forums and was wondering about the JBA cat back. Anyone run this? I have an 03 6.0L

Not a soul?

UPS came and dropped it off, I opened it up and they use manaflow mufflers? Are these good sounding mufflers?

Thats interesting. I thought they had there own muffler design. Magnaflows are great, so it should be a nice kit either way.

I run the JBA muffler with the K&N embosed on the tip, and yes mine did come with the Magnaflow muffler as well. Overall I'm happy with it the muffler itself has a nice sound without that terrible interior resonence to it. I've had mine installed for over 2 years now...the tip looks like **** but Jersey winters will do it to you everytime.

I had the JBA exhaust kit as well on my 98 Sierra Z71 with the 5.7L. It did have the K&N labelling as well. Overall I was very pleased with it and was able to get it for 200 dollars off since it was off the wall with a few minor dents. It sounds great and held up really well in Calgary winters. The only problem I had with it was the tip staining as well....I'd have to polish it with 1500 and 2000 sandpaper on a regular basis
