View Full Version : CAI installed, on to Exhuast. Advice on exhaust with NO drone in cabin!?!

06-27-13, 08:34 AM
Ok guys, I installed the Air raid last week in my garage on my 2013 cts-v sedan.

Now looking to install the exhaust.

What setup has least amount of drone in cabin, and sounds pretty mean on open throttle? I'm not looking to sound like dukes of hazard, afterall this is a caddy..hehe

Something throaty sounding.

I'm in Houston, Texas.

I was going to go that route (have airaid installed too) but seems like most exhausts you can only hear really from the outside. The noise deadending inside our cars is pretty substantial. Consensus is the corsa's sound quieter putting around and really wail on WOT.

I was going to get Corsa's but now I might just get cutouts. Still deciding.

I can tell you from experience on my last couple of LSx powered cars, Corsa cat-back is the only system I have had and ever hear others never mention issue of drone. Now you pay out the ass for it and it's really only going to give you better sound (not much in way of hp) but it is the perfect balance of factory sound at cruise and great sound when you stomp on it.

No drone with Corsas!

What about just gutting the second set of converters?

Second set of converters? What and where are the converters located? I meet with muffler shop at 10am tomorrow. He recommended we keep resonators and add magnaflow exhaust in place of factory (enormous) mufflers.

As for drone, if it is a well insulated car, then I'm not too worried about drone. My Vette had straight pipe from cats on back so anything quieter than that will suffice. I think.......


Essentially, what he will do is replace the stock muffler next to the tailpipe with a magna flow. Leaving the rest of the piping stock. Can someone point me to a clip or feedback what this sounds like?

I'm going Kooks headers and X pipe to factory exhaust. I'm told that is populor with a great sound and no drone cruising on the highway. And headers is where you a bit of power. Not much but some.

Get headers that don't drone, from what I have read the stock exhaust flows quite well. But I like the sound of headers!

Corsa Sports are probably the best overall, but they are a bit pricy for axle-back pipe and mufflers. I'd like to do headers too, but you need to tune the car and technically the warranty is bye-bye at that point which I'm not a fan of as the LSA isn't the cheapest engine to replace if something crazy happened.

Won't get any extra power without headers if you are just talking exhaust. Headers will give better flow. Thus better cooling.

Never heard of anyone modifying their exhaust to get better cooling...

Well if you have an overdrive pulley it creates more pressure which creates more heat. When you headers on it creates more flow keaping HP but reduceing pressure and heat do to the increase flow. Thus it alows better control over temps. Plus you won't melt the stock cats.


Overall... better cooling....

stick with stock mufflers and get a set of kooks headers, you will gain power & sound ;)

Mufflers no matter what brand gain nothing but a sound note.


Any headers will gain some power. Overall sound will come with it. Mufflers are mufflers. Dont waist your money... stock mufflers are no different than the ither brands. Its just a different sound note. Power comes from the headers.

Listen to videos of kooks or ARH headers with HP CATS and stock mufflers. The sound at idle is decent, apply the power and you will LOVE the sound. If you have ANY thoughts of headers in the future, wait and get them before you buy Corsa's or any other exhaust. The stock rears are good to 700 RWHP...

That's what I did. Kooks and X pipe to stock mufflers.


Would have done SW but they were two weeks plus back ordered.

This is great info! Love this forum. Convinced stock mufflers with kook headers is way to go. I'm going the hennessey way with v700 setup so iill ask them about headers install. Thanks for the info!
