hey guys

finallllyy have time to install the quad exhaust

ive seen various set ups on the forums


but has anybody used a dual in dual out muffler?

I want to do what 2MCHCARs set up is like....with a muffler in the middle of the car....but i want the 2nd cats to connect directly to the muffler instead of it connecting to a 3" Y pipe

I am also wondering what the diameter on the secondary cats are...so I can order the correct inlet for the dual muffler

Thanks

Kevwood

I believe the OEM diameter is 2.25", why do you want to keep the secondary cats?

Not 100% sure, but I thought the secondary cats diameter was 2.5''

sleepyheadzzz

i thought 2.5" also on the 550....not sureeee.....i wanna keep second cat because i don't want it too loud...my resonator is already removed too....

i am ending up having to pay big bux for the amg tips from parts.com

but magnaflow is having a fatty sale on amazon...the muffler is 100 bux lol...i just need to know the measurements!!!

I asked Wes a while back, its 2.5".

I just removed my resonator a few weeks ago, and I can confirm the diameter of stock piping is 2.5".

I think the car sounds better with no secondary cats

sleepyheadzzz

THANKS you guys rock!!!...i'm debating between the 11" versus the 14" long oval muffler....do you guys think 3" will make a difference?
I am mounting it where the resonator used to be

I sound like an Extenze commercial ...i know lol

From what I hear, the shorter the muffler the louder it will be...

Kevwood

Correct. The longer the muffler the more surface area the exhaust gasses have to pass over the perforated surface and have sound absorbed. If you don't want to add a lot of volume but rather a nice deep tone, use the longest muffler you can kit under there. I think the one I have in place of the resonator is 18".

sleepyheadzzz

18 inches?????


i'm impressed lol jk jk...

Kevwood

That's why I get play

sleepyheadzzz

hey kevwood...was 18" the whole length or the body length...

would you mind sharing the part number?? i wanna go as long as possible...don't want it too loud...can't stand drone

Kevwood

Mine is a dual in single out so it won't help you as you want the dual/dual. My first setup was so loud and had such a horrific drone that I added another muffler in the back.

I have an exhaust thread up, AMS/Magnaflow review thread or something it's called... Have a look and read, it might give you some ideas or at least answer a few questions.

togaclk55

How can you tell if you have drone? All I hear is the roar of the V8

sleepyheadzzz

i know u do...i read that thing front to back like 5 times LOL LOL

togaclk55

So I'm not the only one...

Kevwood

Good reading for when you have insomnia, it'll put you out cold!

Kevwood

Everything inside the cabin resonates and your ears try to commit suicide... Drone is worse than a wife nagging on you, at least you can put yourself in a happy place when she goes at it.

togaclk55

Pretty sure I don't have drone then
