From a person who had installed both the Borla 4 tip and the Corsa Touring; I stuck with the Corsa. Although the Borla sounded great at idle (like a big muscle car) and at WOT, the low resonance (the dreadful drone) was sooo annoying at normal cruising speed 
, I stopped driving my car 
. I even installed a heat shield & dynamat in the rear & cabin area, but couldn’t drown out the resonance 
.
I selected the Touring over the Pace system because I am planning to install headers and didn’t want go through another exhaust change if the Pace was too loud or drone. The Touring is quiet, probably one step louder than stock, except at WOT.... you then hear the roar. And another note: the best way to choose your exhaust is to personally hear it from both outside and INSIDE ... and at different speeds.
PS: The Corsa does sound like a motor boat at idle...

yep...personal preference
I'll say it again...this forum is great and I truly appreciate all the experience. Based on all that I have read, I simply need to make a choice of sound that will allow me to enjoy the ride even more! Thanks again forum.

If you have a great deep muscle car sound at Idle, then you will have resonance or drone at cruise... If you have a quieter idle, with pulses separated as far as possible, then you will have no resonance at cruise...
This is not guess work , its simple science.
Anyone with Borla's, will indeed have a great Idle, but at the cost of cruise..Anyone who claims different is just fooling themself. When you buy Corsa's you will get the GM logo on the box. That didn't happen by accident. They delivered exactly what we wanted...and we did not want any Drone at cruise. Like I said those who claim no drone with Borla, just want as many people to jump on the same ship that they chose... even if it is sinking.
BTW I am Not bad mouthing Borla, they sound great... but not at cruise. To prove my point , many people will justify buying Borla and even stretch the truth, one of my best friends had Borla, after a two hour trip to New York with him, I had a head ache for two days, I asked him if he thought that drone was good. His answer was" OH You Get use to that"... I refused to go in his car as did his wife.... he now has Corsa Indies, he is happy and so is his wife. The Ones who have had Borla and posted that they had terrible drone, and changed to something else, have no Axe to grind, just honest input.. those who have them and ignore the drone, are just justifying their choice.

I repeat, in my car with a Bassani X pipe, I HAVE ZERO DRONE from my Stinger. Sure you can hear it a little at cruise but that's the way a muscle car should sound.

Alright here is another options to confuse matters even more. I have LG headers with the X-Pipe that came with it, High Flow Cats and TI exhaust.
Anyone have any experience with the A & A Mod either the stock exhaust or the TI system.
Here is a link to the modification, there shouldn't be any drone with this setup. Exhaust Mod Installation

Very little if any, I would be surprised if you got more then 3 hp. Exhaust system from cats back are not meant for HP but for sound. Someone correct me if I wrong. But I've seen dyno with after market systems and stock and most of the times it's questionable. From pull to pull

GHL Bullet's w/ Quad 4" Tips, no LT's...yet; Resonance? around 1500 they get 'louder' when under light load; On freeway (2:73 A4) in cruise control at 75mph can't really hear the exhaust though. Have taken 10 hour trips in car and not bothersome at all.

How do the Pace Cars sound with headers as that is my next step? Drone at cruising is my biggest concern. As a GM guy what headers do you recommend that deliver quiet cruising but nice WOT?

I HAVE ZERO DRONE .. now Zero means none, your next statement was:
SURE YOU CAN HEAR IT ALITTLE....... so which one is it? Zero or alittle...
alittle means you have it.. just as I have said... and NO that is not the way muscle cars have to sound... Like I said , you are only fooling yourself, and you have, in open forum, proved my point about how Borla owners fool themself.

Headers change the pulse width, and I have no expert advice on the multiplication of pulse widths due to different types of headers headers... sorry!
headers and cams and increased idle due to manifold vacuum loss makes the car sound louder at idle...many people opt for touring, or stock Titainum, just to keep the noise level down in these applications...Having delt directly with Corsa Engineers I'm offering my insight to those with stock internals on LS1/6.

Maybe you should tell GM they should have chosen an exhaust that makes the vette sounds like it's got a pair for once..........a stock Mustang GT sounds meaner then a stock C5 or C6.

The half dozen people who pmed me to thank me because the one thing they do not want is drone at cruise... most mature people who bring their wife along do not want to subject her to the drone... and as you have said, Borla is a no brainer... they have drone... the original poster wanted opinions, thats what I gave , my 45 years of automotive technology the last fifteen with GM and the last seven devoloping the C5. Maybe you should have bought a Mustang.
