Rasp and pinging ARH LT Headers with Borla ATAK?

mikedeezxxx · August 22, 2019

Yeah I never said anything about expecting to achieving a quiet exhaust. I bought the ATAK for it's sound and aggressiveness. I knew and expected it to be loud but I am also trying to have it sound clean through all gears since it's a daily driver. Sounds good wot but man passing 1/3 throttle sounds poppy and raspy. Kinda like a raspy import but with 8 cylinders. There are ways to achieve a clean sound. I had borla, kooks with off road pipe on my 2000 camaro and it sounded good. That was a 5.7 ls1 and I am new to 6.2's . Whole reason I chimed in on forums for peoples experiences and methods of how they controlled the rasp. Not trying to have my 50k + daily driver sound crappy until I WOT.

There’s just something about the sound of a (REAL) LS motor with headers and exhaust. I have a 2008 Trailblazer SS with 6.0 LS2, long tubes and Borla dual exhaust, that sounds incredible. No comparison to my Silverado sound at all with same components.

I have Kooks Long Tubes with Green Cats with a Borla catback exhaust. It is not that loud. It sounds great when full throttle and quiet rumble inside the cab when normal driving.

Which borla cat back exhaust you have? Touring, S type?

Thanks for the reply. I will definitely look into Jones XL if I don't like the way the resonator sounds.

They're a little over $70 on ebay right now with free shipping. Search for Jones Performance Turbine Muffler JT3535XL

I added a 3.5" vibrant resonator right between the y-pipe and mid pipe today. It really made a difference! This is what I was looking for, close to the Borla ATAK before headers and it is still aggressive and loud when you lay into it. I placed the resonator as far up close to motor as I could to stop the sound early and it definitely make the cab really quiet when cruising and passing half throttle it has a nice rumble and slightly aggressive. When you floor it, it wakes the beast and surprises vehicles around you. Definitely recommend this route for people wanting LT header w/ high flow cats for hp gains while keeping rasp down to a minimum.

Is that the 18" resonator?

Sure is. 18" Vibrant bottle resonator for a 3.5" mid pipe.

I might give that a try. I have ARH with a catted Y pipe and a Jones 3535XL muffler dumped right after the axle. It drones a little bit from 1500 to 2000 RPM. I'm hoping this up close to the Y pipe will help with that without quieting it down too much.
