Hey guys!

Currently, I have an ATLP quad exhaust system with j-pipe and hi-flow cat installed on my 2005 TL. The cabin drone is starting to get to me so I'm thinking about installing a resonator to tone things down a bit. It's not so bad when it's just me, I can just drown out the drone with my music, but when there are passengers in the car, it's kind of harsh. Especially because I can't blast my music, plus I feel bad for them because the exhaust is so loud.

Has anyone with an ATLP non-resonated exhaust system installed a resonator afterwards? If so... What was the difference in drone/overall volume? I spoke to a local exhaust installation shop and they said it'll cut down the drone by about 25%. True/false? Any particular brands I should aim for?

I love the sound of the exhaust and I'm hoping the resonator won't interfere with it. I just want the cabin drone to be addressed.

Thanks!

Any luck? I am looking into an ATLP exhaust for my 3G TL, does any one have a video clip of an atop installed on a TL with a resonator?

vibrant, that's what i'm using
it got way too loud after i installed the supercharger

i just ordered the magnaflow 10436 resonator to add on to my ATLP V2 quads. i should be getting it in this week and i am going to have it welded on ASAP. il post back with my results.

I've got a decent video of mine..I will try to upload it this weekend. It wouldn't let me upload it from my phone

By the way my res v2 quads has no drone but I assume my res lowers the volume on the beautiful sound. Mine is a magnaflow.from heeltoe

I got the Magnaflow 10436 welded on last week. I got it TIG welded by a local guy I know, he did a great job.

I have been driving around for the last 4 days and definitely notice a difference. All the drone under 2.5k RPM is gone. Highway drone is gone. The outside noise is unchanged. The only drone that comes in is a very mild drone from 2.5 - 3k RPM, but in comparison to before, its very bearable so all in all, im satisfied.

thanks for all the feedback, guys! now all i have to do is decided whether or not to get this done. what if i regret it later on?? like... "damn! now it's TOO quiet... i should've left it the way it was."

another concern i have is about ground clearance. something scrapes on the taller speed bumps... i'm guessing it could be the heat shield around the hi-flow cat? will the resonator give me less clearance than the heat shield? if that's the case then it would pose a problem lol... i'd be scraping on all speed bumps lol.

I had the same problem, but now that I'm driving more people around in my car, I realized that using the music to drown out the drone wasn't going to work anymore. I installed the vibrant resonator thinking "this is is, its going to kill the beautiful sound". I was wrong, the vibrant resonator not only killed the drone inside my car, it kept the beautiful tone outside. I find myself driving with the windows down when I want to hear my exhaust and windows up when I want silence. This is definitely the best resonator to go with if you want to reduce drone and keep the sound.
