I was tired of how much drone I had with my magnaflow. I purchased this resonator after talking to Tyler and man was it a game changer!! Knocked down the drone soooo much and really made the exhaust sound great!! Best resonator on the market!!
I did a cat and muffler delete on my 09 Impala LTZ and it was a little to loud. I put this resonator on and now it's sounds good with a great exhaust tone.
Awesome sound and does exactly as they claim.
Put this on my B20B vtec Civic 2.5 custom exhaust with LT headers. Car sounds great now almost no drone now, Clean no rasp or can sounds. Also car is not obnoxiously loud now, only when you get on it with just the right tones/sounds.
Nice added purr!
After 18 years, I replaced my stock resonator with the ZZP 20-inch universal resonator on my 2002 Pontiac Bonneville SSEi. I also added the ZZP H-Body Downpipe (with catalytic convertor) in front of the resonator. The resonator was a super-easy install, looks great, and added (along with the new downpipe) a little more aggressive growl, especially when you rev the engine (I do have a fender well air intake that appreciates the new ZZP add ons!). I have not replaced the stock mufflers yet, but expect to gain a little more purr once that is done in a few months. The ZZP resonator is slightly shorter, with a slimmer, sleeker design than the stock resonator. When replacing the downpipe/cat and resonator I needed to add a short section of pipe (6 inches plus overlap) to connect the resonator to the remainder of the existing exhaust. Again, very easy to do. If you are needing to replace your cat and resonator then know that the ZZP products were less expensive, better quality and, of course, designed for the GM 3800 engine.
