I'm wondering how much drone the Tsudo catback type S with quad tips would have cruising on the highway, road noise seems dominant on a stock TL at highway speed.
This would be with a ATLP j-pipe as well.
Anyone have the Tsudo cat back care to share?

 

Anyone know which catback exhaust that are currently being sold with quad tips (Tsudo, OBX, ATLP ?) has the lowest rasp or least drone?

 

I have this catback without the j-pipe and there’s a noticeable drone from the oem exhaust. But it’s not overbearing. I’ve had it for about 5 years now and I love it. I wanted something noticeably deep at idle but not annoying to keep it classy. Can’t speak for the j-pipe though…

 

from my research. The tsudo is raspy and the other 2 arent. Depends on the j pipe as well. Rv6 v3 and tsudo are both going to make your exhaust raspier (because of the longer pipes). And if you’re worried about drone, add a vibrant ultra quiet resonator.

my setup is: pcd, endless v2 j pipe (shorter pipes) w/ test pipe, resonated atlp v2 + vibrant ultra quiet resonator. So, catless with 2 resonators and 2 mufflers. It’s only loud when i get on it. There’s no rasp and minimal drone on the highway
