Exhaust without drone
 

Has anyone with Long tubes found an NPP exhaust that doesnt drone at all? pretty much looking for a replacement for the stock muffler. i tried the SW axleback and it was just too much with ARH 2" uncatted LT's. THanks in advance!

(edit) i should clarify i am already assuming a certain level of drone with 2" long tubes and no cats. I am looking for something that is Bearable with the valves closed.

So you want a dual mode exhaust? There's only a few options out there, Borla claims their S-Type and ATAK systems do not drone but if their last generation of Camaro exhaust was anything to go off of, that's a lot marketing hype. Adding headers + no cats will challenge any exhaust to not drone and the ONLY brand I would trust would be Corsa. But they're not dual mode (Not that you really need it, your foot controls the noise with Corsa, keep it under 3000 and it's quiet, go WOT and it's loud).

Any muffler system, even the OEM one, will drone with headers with no cats.
Cats act like a resonator close to the exhaust ports.

Adds long tubes and deletes cats and complains about drone? What did you expect?

Let me clarify, you must think i'm some idiot. I meant an acceptable amount of drone. I had the SW axleback and with the valves open it literally made me Sick. I Am looking for an exhaust that has a reasonable level of drone. not no drone. Also my car is on 15 pounds of boost so the cats would've just blown out eventually.

this system looks alot better on the car than in the pics online. looks nice.

Corsa is definitely on my list. just seeing if anyone had good luck with another NPP system first. ive got corsa on my 18 denali now and then my last 4 c6z's, c5z, gen5 zl1 and even my E92 M3 lol i should have stock in corsa at this point.

The stock npp muffler has no drone in my experience

go talk to Howard at Redline motorsports in Pompano

My NPP does not drone, but if I wanted something a little louder and no drone it would be Corsa.

I am having some Kook's Long tubes installed this week (no cats), and keeping the stock mufflers. I'll let you know how it sounds on the highway. Should be done by Friday.

The owner of Speed Inc. has a ZL1 with Long Tubes and stock muffler and it sounds great (open) and reasonably quiet with the valves closed.

that's what I have now and I love it but the muffler has an internal rattle and my warranty long gone lol looking for something different but the Corsa is looking pretty good. I also came across the Meistershaft system which is a German brand that I had on my last M3 and it was incredible but they want 3k for the catback. that's tough to Swallow.

Link to the Meisterschaft please.
