Exhausts loudest to quietest

**Mike0202** · 10-30-2010, 02:28 PM

I see alot of people on here who want/need a quiet setup for where they live, and alot who want a loud set up, or something in the middle. So I thought I would try and put together a list to try and help. Lets assume a bolt on car (stock internals). If my list sucks let me know and ill fix it. I know I am forgetting alot of setups. I would like to get around 20 different types.

Assume FULL bolt on car. Full exhaust, ls6 intake, ect.

1. Cut out (Open headers)
2. True duals dumped
3. Loudmouth1/Bullet mufflers/4 inch Mufflex
4. Texas Speed Rumbler/Loudmouth 2/ FM 10 series
5. Gmmg Catback/Borla (Open Plate)
6. Flowmaster 80/40 Series
7. Borla XR-1 (Borla Mouth)/Corsa Catback
8. Bassani Street/Flowmaster 80 Series Catback
9. Hooker aerochamber/Edelbrock RPM
10. SLP Powerflow/Flowtech Warlock
11. Magnaflow Catback
12. SLP dual/dual
13. Stock

There is no way that the Flowmaster is louder than GMMG, not even close. I have had both.

Also, headers and ORY would change the order of this list for sure.

fixed

Did you have the 80's series catback? Those tend to be quiet.

Lets assume the car has long tubes, since most do.

has any1 ever heard of spin tech on here!?!?! they sound really good IMO

**Firebirdjones** · 10-31-2010, 04:54 PM

Those listed are either 2 1/2 inch duals or 3 inch catbacks.

We should throw the 4 inch Mufflex system on the list too

It sounds pretty aggressive

Subscribed.... selling the stock exhaust for scrap in the spring...

**xmarkx** · 10-31-2010, 08:52 PM

stock cats and Y with muffler delete should be added some where on there. bad quality but LOUD!

I'd have to say it probably ranks up there with a true dual dumped with very loud bullet mufflers. So probably top 2 or 3 or so.
I can tell you when it fires up at a cruise among 100 other cars, people turn around to see what it is

The sewer size pipe gives it a very deep aggressive sound.

**02sunsetorangeZ** · 11-01-2010, 04:32 PM

another thing, i have LT's and true duals and x pipe, over the axle, magnaflow bullets over axle. its really not that loud at all. Especially in the car its pretty quiet, i will try and post a video for more info

**BashamWS6** · 11-01-2010, 07:21 PM

Nice muffler...I was going to put those on my car but went with the bullets instead. IMO Spin tech sound great at low idle but at WOT very loud and raspy.

**Mike0202** · 11-01-2010, 10:19 PM

I have a 40 series welded into the stock ws6 catback (3in I believe), with long tubes and a catted 3" Y pipe and I cant believe how loud it gets wot. A little too loud for me lol Glad I didnt get the loudmouth.

**blackbird0230** · 11-01-2010, 10:45 PM

Open headers for the number one spot. Woot

Got it on the list already.

**RyanJM** · 11-02-2010, 11:40 PM

Slp also makes the powerflo which I have close to a magnaflow.as far as loud since it has 3 mufflers. Deep at idle and cruising and wakes up at wot especially from 4 to 6k, can wait to hear it with the ms3 cam when I get it back.
