Has anyone put the full kit on their truck(inc. cat)?
Did it sound good? Loud or Quiet?

Just put Headers on and had a new pipe ran to my cat(2.5"). But am looking at a new cat and new muffler for my truck.

Any other brand that is better?

 

Do you have a V6 or 4cyl?

I'm pretty sure they are selling magnaflow products which are very good. It's a straight through design and from their photos it looks like they are using a smaller case muffler.

It will sound like a 4cyl or V6 with exhaust. If that's what you want then you should be happy. If you want quiet you might want to look for a bigger case muffler. The large case magnaflows are very quiet.
