Okay....as I always say, HP mods before good looks/sounds. Well I am friggin sick of the "tin can muffler" sound I got by removing the cats. Any reccommendations on how to quiet her down? It really agitates me around 2500-3000 rpm's ... please help!

 

Glad to hear I'm not the only one that thinks removing the cats sounds like S**T. To me it sounds like a old Ford with glasspacks. Even worse when your standing outside listening to it pass by.

 

Hmmmm......I hate to sound stupid but would putting cats back on help?

 

well I suppose that it would, but I dont like the feeling of regression. I know that u don't gain a whole lot by removing the cats, but every little bit helps, right? Is there a quiet muffler made for our car out there?

 

yea i agree, when cats are removed it gets kinda anoying a bit...but hey, I still love making everyone turn their heads within a mile radius. When you get on it yea it sounds kinda crappy...but i dont know, theres just something about THE LOUDNESS

Oh btw...drive underneath a 6 lane highway overpass, and floor it with the ttops offf and windows down. Its something you will never forget...I did that yesterday with a red c5 trying to keep up with me.

 

You should get a high flow cat.

 

how about putting an extra dynomax ultraflow between the i-pipe and y-pipe in place of the cat?

I have an offroad y-pipe going to a flowbastard muffler, and it doesn't get that tin-can ratty sound, luckily. i'm switching over to hooker aero's soon though, so hopefull that ratty sound won't come back.

 

A High flow cat would work, but could I do it with just 1 cat with me having a 96? I have o2 sims, so it shouldn't be a problem right?

 

Try Headers, no cats with the cutout open

That's the way I've been running for a few weeks now(had it capped for the longest time)

Now that's L O U D!

I like the Dynomax Ultraflow. Combines high flow with great noise reduction. Click on the 1st video on my webpage to hear how it sounds at WOT. Some people have but a Dynomax Bullet muffler in place of the cat, and that seems to help also.

 

I personally LOVED the sound of no cat. I like it way better then my cut-out. But yea my car is sooo loud its annoying..

 

I have Macs, Mac y-pipe, B&B tri flo with a cutout.

My high flow cat was gutted (bought it used that way), and it sounded like crap.

Get an offroad pipe instead of the cat. The resonating sound disappears, and the sound is much cleaner.

 

i think a lot of people go with a bullet muffler in place of the cat. Suppose to be almost as loud but less raspy.

 

Zman,

Just run a different exhaust tip at the rear. I took my cat of too and got frustrated with the sound after a while. I put some tips that go past the rear bumber about 1-1.5" and that definitely helped tone down the inner cab sound. You can probably get some cheap ones locally or add an extension to the pizza box originals---if thats what you have---they have that at local parts stores around.----Just a thought----You figure it out.

 

yes, but does it sound *good*? Loud doesn't always mean good... although some people on this board seem to think otherwise. I'm actually trying to quiet my car down a bit right now..

i've heard a friend's LT1 car with mac headers, ypipe, offroad pipe, and a full open borla...... on a stock cam.

it didn't sound too good But yeah, it was super loud...
