Equal-length header sounds

You installed simulators when you did your equal length headers?? I thought you had the RR-Tune which would negate the need for simulators

Unless your car is from out of the US, after market cats don't clean the exhaust enough to not trigger a cell. If you get after market headers, you'll need a simulator/conditioner or a tune. Even if you install after market cats.

IredSF, can you elaborate more on the setup? The QES drones loudly at low rpms. How did the sound inside the cabin change? Is it louder? Does it drone more or less? How does the exhaust note sound now? I heard a little rasp, it still sounds bad ***! And it looks like it pulls harder. Also, on the install! Did you have to modify anything to the exhaust? For it to bolt up. Thanks in advance!
short answer my initial impression was CORRECT, WAY LESS DRONE, way less VIBRATION, only pure EL Header and Qes exhaust sound!
im not kidding huge difference, worth it alone simply for removal of the drone/ resonance.
now that the car is all heathy again, it's easy to tell. It's unquestionably BETTER LIKE 90% eliminated.
ill get more sound clips up now that's she's healthy.
thanks to mike @FIGS and Simon @ rr for helping remote diagnose and resolve. Really appreciated it from both of you guys. (mike u nailed it, loose ground connection in wire bundle)
hope that helps folks figure out what's best for them
for me
same power gain
+
el sound
+
drone killer
win win win

my codes btw were unrelated to emissions control issues so it maybe that your right and unrelated. Had conditioners revmoved because
a. Unnecessary and potential for problems.
b. Rr tune suppresses cel codes for emissions issues anyway.
so just as a precaution based on advice and to avoid any potential issue just had them removed, unneeded at any rate POSSIBLY problematic.
btw for FYI dipstick solution (relocation ) was required on my el header install, for planning purposes for those thinking about going this route

Great to hear you got your issue resolved, IredSF.
Scheduled an appoinment for 9/13 to have my long tube el headers installed. Will be ditching the aftermarket cats at the same time, f the smell. Was going to install 'em myself next year, but after hearing how they sound I can't wait.
