Reviews for Quadratec Competition Cat Back Exhaust System by MagnaFlow for 04-06 Jeep Wrangler TJ Unlimited with 4.0L

Perfect fit and great tone. Best value on the market. Used a small spacer in the rear hanger to avoid contact with my Quadratec hitch.

Nice kit. Uses stock hangers. If you have an aftermarket hitch, it may make contact. Nice tone and no drone. Just what I was looking for.

It’s a perfect replacement not to mention easy to install, looks great and isn’t too much louder than stock! This is clearly the best value out there in my opinion and you don’t have to sacrifice anything!

I installed on my 2004 LJ and took about 1.5 hours by myself removing skid plate/tranny support, cutting the bolts off and the original pipe back by the axle. Yes, you will need to procure new nuts, but that’s it. If your lucky enough to unscrew the nuts then you could probably do it with the skid plate on?

I’ll post pictures separately...

Fit perfectly on my 2006 Jeep LJ with no problems at all. Very easy to install I just cut my old exhaust out with a saws all. Just as quiet as the OEM exhaust at an idle with a good throaty Sound when you rev it up a bit. I was very impressed with the fit and finish of the product and it was packaged very well to prevent shipping damage.

It fit up great without any problems. Perfect installation. Maybe recommend customers to use 2 new nuts at inlet.
