I have an 07 3.6L, are there any under the hood/intakes or muffler/exhaust upgrades I can purchase that'll give the car more vroom?

1. Get engine up to normal operating temp.
2. Pour about a gallon of ice water on exhaust manifold.
3. You will hear your car about a mile away.
4. Slight problem: r/r exhaust manifold is not cheap.

K&N/volant intakes. Corsa or no exhaust. Tons of stuff here...run a few searches. This forum is nuts...people switch out LED colors for fun!

How different would the car sound if I just install an intake vs. if I just install a new muffler? And can I just install Corsa mufflers and keep the catback and all the other stock pipes?

Man. I put the K&N cold air on my 06' 3.6. It sounds really awesome. The intake is pretty loud at all ranges but there's a deffinate growl under the hood around 2,500-4,000RPM at all throttle positions (you can hear the air getting sucked in...ROOOOOMMMM). And then it will die down a little. At full throttle to red-line...it's just crazy noizy. I'll get the wife to stand out side shooting a vidoe while i fly be her if you'd like.

For the most loudness go for new mufflers or straight pipes.
The intake just adds sound to the engine bay.

The mufflers will add more a rumble to the rear.
And you can just replace the mufflers and the leave the cats in place.

CAI or muffler mod was one of the first things i considered for the CTS, but i reeeeeeally didn't want my elegant Cadillac to come out sounding ricey in any way. i suppose it's harder to f up with a V6, i'm just so used to people modding up their inlines and making them sound like wind-up toys.

If I had the choice, I'd most likely change the muffler instead of adding an CAI since adding CAI will void pretty much all parts of the warranty I have.

Is it possible to buy just the Corsa dual exhaust/dual tip mufflers or do I have to get the whole exhaust system?

I hear ya, I'm trying to stay away from that Civic/Impreza squeak toy sound. I want an American muscle sound.

Actually, it's pretty tricky to get the muscle-car sound out of a six; they can sound just as ricey as any 4-banger. Sound-wise, our engines are closer to a 350Z's than they are to a Mustang or Corvette's.

Remove the stock briefcase mufflers and go with straight pipes. it's cheap and sounds great. drones a little up hills but worth it if you have a lead foot.

straight pipes might be a little raspy but yes they will make the car louder.

the corsa exhaust is in my humble opinion way over priced for what it gives you. (by the way, the corsa comes as a full bolt on from behind the cars all the way out, no way to just get the mufflers and tips)
It would be cheaper to go to a local shop and have a custom exhaust done.

You may want to look at dynomax mufflers, either the ultraflo or super turbo.
I had stainless super turbo's on my 97 grand prix gtp (supercharged v-6) they gave it a nice deep rumble, no drone at highway speeds (something you want to avoid) and really had a voice when you stomped the gas.

check youtube for sound clips.
when listening, listen "past" the sound. its hard to explain, but try to take into account that the microphone on most cameras really can not capture the low end rumble of a good exhaust.

here is the dynomax ultra flows on a v-6 mustang.

I remember reading on this forum that you can't put Borla with 3.6L V6?
