    Which of the cat-back systems are street legal in California?

    PaulR

    • Since the MBRP Installer Series Cat-Back Exhaust system does not interfere with the catalytic converters it is not subjected to CARB regulations and would be street legal.

      Review from MBRP Installer Series Cat-Back Exhaust (00-06 Wrangler TJ, Excluding Unlimited)

      Good product

      Overall the project took me 2 hours but also including some much needed cleaning on areas underneath while the stock equipment was removed. Do yourself a favor and the night before hit the bolts on the old exhaust system with some PB blaster or something to loosen up the rust and dirt. I recommend doing this on a lift to save your old exhaust and prevent cutting etc. Removing the new exhaust was simple and I believe it sounds better and throatier while not obnoxious. Performance is also slightly improved with responsiveness and slight gain in torque, it is noticeable. Combined with a cold air intake will also yield great results. Definitely a sound upgrade that you won’t regret and it also looks and sounds good while maintaining the appearance and sound of a Jeep.

      Perfect Tone

      Despite being bolt on, I needed to have a muffler shop install it because of a previous owners poor modification. Also the muffler itself was not black as advertised but I expected that from previous reviews so not a real big deal. I still give it 5 stars for sound, performance and overall look. Nice upgrade!

      Awesome!

      Very high quality exhaust with a great sound. Everything fit perfect and looks to be of superior quality. I was a little concerned when the box showed up torn open, but everything was in there. I upgraded to walker band clamps because I like them better than the u clamps that came with the kit. Overall I'm extremely happy with the kit and sound. Big improvement over stock, but not too loud and very minimal droan that I don't even notice after a few days.

      Pretty Quiet Exhaust, decent note

      I expected this exhaust, paired with the BBK Shorty Ceramic headers to have a louder exhaust note, its actually more quiet than my previous no name ebay exhaust..

      MBRP

      Fit perfect no issues installing pretty self explanatory, hardest part of install is just getting the old one out, just cut it out. I didn’t put the tip on just because of where it comes out, it will probably get trashed from slinging rocks out of my tires, but it looks great even without the tip! Took about 2 hours just because of the old one.

      MBRP CAT-BACK

      The installation takes more time than you think because you need to drop the skid plate under the transmission to get to the bolts, other than that pretty straight forward. The sound is excellent, not to load and the tone great!

      Misleading Product

      I can only review the delivered product at this time. I just opened the package to find only the tail pipe painted back. That may not change the overall quality but it was advertised as all black.

      Was a little tricky to get the old exhaust out, the old boots broke off easily, but I didn't need them anyway. Overall love the exhaust, it has a nice growl to it.

      heavy duty, great sound, direct fit.

      Arrived quickly, all in one box. Easy installation after I removed the transmission skid plate which provided access to the existing bolts. Reused existing rubber hanger (one was perfect the other was worn but more than good enough to be reused. Hardware appeared to top quality and fit perfectly.

      Great sound for the price

      Shop install for $65. They opted to cut the old exhaust out behind the cat flange and weld the new one in. Overall, sounds great for the price.
