Really? That's it?

So I recently upgraded from the v6 to the 2010 ss. Love the power increase and having a manual. (also need to update the site info). Here it is


The vehicle also came with a aftermarket exhaust. And don't get me wrong it sounds awesome. But it doesn't seem loud enough. At idle and low rpms it seems to roar. But at WOT it seems to lose that "uumph". My v6 with MRT v1 was louder it seems. So I figured I would dump the exhaust and go with a muffler delete. So I take a look at the exhaust and I take a look under the car to see the exact exhaust I was dealing with and boom I see this!



That looks like straight pipe to me! Man here I thought straight pipe would be incredibly loud as hell. Drone through the roof. But IMO it sounded rather tame. I shoulda realized It was straight piped with all the decel pop I was hearing. So my question is what small changes I can do to make it louder? I know LTs would help but that is out of the price range right now but definitely planned down the road!

High flow cats maybe? Or get rid of them?

straight pipes on these cars don't really do too too much. I removed the resonators and it was still quiet. The car remains quiet because there a 2 cats per bank.

LT's or a removal of the rear cats are the way to get more volume.

Don't know much about straight pipes but maybe a aftermarket exhaust is in your future

this is true.

i had a pypes pype-bomb system before all the changes

i cut off the exhaust and started it just to see how loud it was..it was quiet.

installed the pypes and it got louder. So i'm assuming the mufflers made most of the volume.

I had the joy of driving behind a club member this weekend with straight pipes (no cats) and headers. It is by no means quiet. Had to turn my radio up pretty high.

So how much of an increase of volume if I have the cats removed?

My v6 on a scale of 1-10 on volume was like a 8 on wot. This is a 6 it seems. But louder then the 6 at idle and about the same at low rpms

Is anything done to the exhaust from the axle forward?

Throwing in some headers with high-flow cats and getting rid of the resonators will definately "open up" the sound a lot.

It's up to you, though, to decide if you want to deal with the Check Engine Light (CEL) that comes with doing long-tube headers or you can go with shorty headers.

There's lots of options

Forget straight pipes or muffler deletes... HF cats, headers, and a cam if you want what an SS should sound like. Be prepared to dump upward of 4-5 thousand.

Fact of the matter is 90% of mainstream consumers..yes.. even people who buy the SS. Don't want the in-cabin sound associated with a louder SS that will undoubtedly accompany with the purchase of headers or cam unless you want to spend the time and money to work past the issue such as J pipes or dynomat... even that won't 100% solve the problem.

Then the flip side of owners are people who think there car isn't loud at all and do everything they can to make it louder to the point they completely disregard tone.

You need to find a happy medium with this car and as I said, that usually comes from long tubes and a reputable company's catback exhaust.... one day working towards a cam. Don't be the guy who disregards tone. These cars with headers are MUCH louder outside to other people than it appears in cabin. I was the same way until I had my wife drive by me and I had the "Oh chit" face.

I agree with getting the long tube headers (ARH here), with a GOOD tuner, because you will have to get it tuned, you should not have any CEL's poping up. You'll get louder and add some hp. The key thing is find a tuner that knows what they are doing.

I have high flows and a solo catback. The hi flow cats really make the car sound louder and meaner, but only when I get on the throttle. At idle (once it's warmed up) it's still relatively quiet. The cabin really deadens a lot of the sound though. I wish I could hear my car from behind while someone else is driving it. Although, that would mean I'd have to let someone else drive it

very well said. i know what you mean about keeping a good tone. thats what to me is very frustrating. my exhaust is still not where i want to 100%. i want a loud, but toned sound. and it seems the louder you get the less toned it gets.

Yea, and truthfully after the cam I wonder if any catback really matters from one or the other. Cat back and header pairing seems critical.. but at that point of a cam you are just blowin violent lope out lol

I love the sound of my cam because of the lope and uniqueness compared to other vehicles on the road...but the borla tone I loved is drowned out by in cabin volume now.
