We can't help you until you provide that information. Get under the car & look for stamped logos on any of your exhaust components. Muffler & tips should be a good indicator of the cat-back system that's on it. The Y-Pipe or X-pipe will be harder to tell, but you will see if it is stock or aftermarket, and if it has catalytic converters on it. Lastly, if there are stock exhaust manifolds or aftermarket headers coming off the engine.

If you don't know what you're looking at, take some *vivid* pictures and post them here.


We can go from there.

BBK makes a muffler? News to me. I'm fairly certain the Magnaflow is the most quiet bolt-on axle-back exhaust available to the 4th Gen F-Bodies.

Just to be certain, take a look under your rear bumper to see what it says on the muffler. This is a good deal on a Magnaflow system for sale here by a club member: http://www.njfboa.org/forums/showthread.php?t=55511
The swap could be done yourself for free, or for under $100 at most any shop.

Does BBK even make cat backs for F-body's?

Judging by your exhaust dumping behind the rear tires, bubba did some exhaust work on your car. Best bet is just to get a magnaflow catback . Quiet but still sounds good under wot...

ok crawled under : the muffler says flow masters omg cheep junk , but the way its set up under there is strange i think somebody did some custom @#%$ work

Flow Master is the ricer exhaust choice of the trailer park V8 owner. Get that off and swap on that Magnaflow. Not hard.


Good luck.

you have a built motor with LTs and no cats.... did u expect it to be quiet?

I had a similar exhaust setup with a magnaflow and it was insanely loud. due to pipe size and no cats, thats what you're gonna get.

If you want quietER, get 2 universal cats and have them welded into the pipes right after the header flanges. then to cut additional sound go for a muffler like dynomax ultraflow or a spintech. If its still too loud after that, i'll sell you a complete stock manifold-back setup which will make it quiet.

insane is an understatement :bertstare: haha

I think your best bet would be to use a dynomax super turbo muffler. They flow well, are pretty quiet but sound good and they are pretty inexpensive.

Anything that's for the v8. The price difference from the kits is because they have different tips.

This is cheaper than the ones on the magna flow site and what most Camaro owners get http://www.speedinc.com/cont.cfm?cid=C0000039 use there is a coupon code for this weekend for 5% off jus go to the main page.

i have magnaflow on my 00 ss, its only got edelbrock shorty headers, a cold air kit and the cat back, and while its not really loud under normal driving, its pretty loud when you get on it. and loudmouths with longtubes are obnoxiously loud.

ok guys i still looking at the magnaflow i like the price range and unless you guys can think of something better i guess thats it

02-19-2012, 08:57 AM
with your set-up anything you put on the car is going to be loud, its an ls6 with long-tubes and no cats. why don't you install cats, it will quiet it down a little.

im just saying that if he's complaining that his car is too loud now. a magnaflow on an off road y pipe with lt headers, wont make it any better.

but hey its his car...

I've had enough catbacks and the magnaflow is one of the tamer ones(sans SLP D/D and 2OTL) with a cammed car.

Don't get me wrong, your car will still be noticeably louder than the legal limit, but it will not be AS loud as it is currently (Flowmaster are generally on the louder side of the muffler spectrum).
The Magnaflow will quiet it down *some,* but don't forget that you're running a cam, long tube headers, and no cats, through a V8.

Below, I've broken down why your exhaust is as loud as it is, in order of significance from greatest to least:

Camshaft: the main culprit in your struggle with volume. However, changing this would require at least 6-7 hours of time (yours or a shops) and would decrease your performance by a noticeable amount. Your car would significantly quiet down, though, by switching it back to a stock, or less noticeable cam.

Headers: The second biggest player in this issue. Doing headers is usually a 3-4 hour job and, as again, you're going to be losing something like 15rwhp (which, isn't as much as you would lose by changing back to a stock cam, but still a significant loss).

Muffler: This is the third largest thing to come into play. You're currently running a Flowmaster, which isn't the greatest, but is loud. It's sole purpose is to be loud. There's no performance to be gained. Swapping to a more quiet muffler, like the ones suggested in this thread, will quiet down your exhaust some. Due to the engineering (or lack there of) that goes into Flowmaster R&D, you'll actually pick up some power by switching mufflers. Win-win.

Cats: You're not running any catalytic converters, right now (Hence the "off road" title, as Cats are a federal regulation). In all honesty, they won't quiet you down much at all. They will remove some rasp, but don't expect your exhaust volume to suddenly change all that dramatically. If you don't race this car often, then I'd suggest looking into some high-flow cats at some point in the future. I have the Thunderbolt Spun Metallic cats, and at $55 a piece, they've been great for both passing inspection and eliminating a little bit of rasp compared to my previous ORY set-up.



In your case, don't touch the motor or the headers. It's not only a shame to get rid of them, but it will cost you a lot in labor as well as require a re-tune. Just pick up a nice muffler (I think the used one I linked you to was only $100 or something, versus the $350-500 that the new ones go for) and work your way towards the front if it's still unbearable after the swap.


If your problem is interior volume, there's always sound-deadening option, by the way. But, that doesn't help if your main concern is with the police in your area.

thanks mike im going to put in some cats for sure and go with the magnaflow , and no im not messing with the motor or the cam that would be way to much money and time ... same with the cam , that was most of the problem when i got the car last year ...

so i will look into cats and the magnaflow thanks again :nod:

When you say too loud, do you mean too loud in normal driving in traffic and under 2500 rpm's or too loud at WOT? Cats will help take of the edge but depending on the muffler design it still might be crazy loud at WOT if the muffler is a straight through design.
