I was looking at the mufflers that came with the exhaust and am just curious if these are what everybodys elses look like. Some pics that I have seen the mufflers have the "pypes m80" written on the mufflers with groves on the end and some pics say nothing with no groves like mine. I'm thinking they might have changed the writing on the mufflers since the pics... Here are a pics of mine. Are these right?

 

I know thats the same muffler casing as mine, but I can't remember if I have the writing or not.

 

i just got mine last week and mine do say M80 on them.....

otherwise they look exactly the same.. mine had grooved ends too...

 

is the inside straight through? the M80's I got are.....

as long as they are the same i guess it doesnt really matter

 

See because i'm looking at this pic and I don't see any grooved ends or writing on the mufflers?? Any tips for the insall tommorow...

 

Didnt you end up ordering from RPM Outlet or whatever that company is that most people have terrible experiences with? You Might wanna call Pypes and make sure if you can because I believe most of the MM systems do have writing on the mufflers... I may be wrong though... Most all the pictures I have seen have writing on them...

 

Also if you look on the Pypes page for the MM system you will notice there are 2 different mufflers offered... Well not exactly different mufflers just one made with 304 polished SS and one made with 409 SS...

I really do not know if that makes a difference or not maybe someone else can explain?

 

The ones from RPM outlet are 304 SS and the ones from Brenspeed are the 409 SS....

304 is better and will last longer.

 

So I got the better ones for cheaper

 

Nice find! I did not notice that...

 

just keep in mind that the aft most hanger rod on the passenger side is gonna be about 1/2" or more too long.... so if you can shorten it i would, i just bent the shiite out of mine to get it to line up

youll see what i mean

 

if you read all the details... youll see that they are the same system...

part of it is 304 and part is 409

 

One difference I did see is that on the grooved mufflers the pipes go on the outside but on mine the pipes go inside of the muffler like the ones in the pic I posed above... Are there two designs or did they change the design... I'm gonna give them a call Monday and see whats up...

 

For what its worth my mufflers did say M80 on them.


PS- PM returned

 

i had the grooved mufflers and they slid over the pipes....

 

I looked into the mufflers and dam they are pretty straight through. Its gonna be like the slp lm's with resonatorsCan't wait to hear it!!!

 

sounds like the same setup then....

i wouldnt worry about any differences in the systems... they should be close enough.

i dont know if there would be any gain to either one any way the way they are built and put together

 

Ya I honestly do not think it would make much of a difference... I was just pointing out what I was reading from the site and RPM Outlet and Brenspeed... I figured the difference was one muffler is made from one type of SS and one muffler was made with a different type of SS... But I defiantly could have been wrong there... Hope the install goes well! I will be ordering mine soon!

 

Mine have the writing on the mufflers.... be prepared to modify the passenger hangers.
