i think i'd call FlowMaster and see if it makes a difference. if it does... i'd have to take it back if it doesn't... well i'd be Okey-Dokey then

 

1000% Agree!!!

 

Based on the images I have seen of Flowmaster internals, it would seem that you'd be introducing a significant flow restriction into the system by installing them backwards. Pressure waves are going to get kicked back upstream if the pic below is correct.

Here's a pic from their website:

 

Hmmmm the thrust welded looks different than that. Actually looks more open and less restrictive to me?

 

i'd

have him put a flange in the system so you can quickly uncap it ,, so when you really want all it has , its there ,,


the flows have an inlet and outlet for a reason

ya spend that kind of money ,, u wanna feel good about what you've spent ,

does it give u that sick feeling knowing its not exactly how u wanted it ?

 

I agree. If it was a straight through perforated core muffler like the DynoMax Welded series, Magnaflow, etc....it wouldn't matter.:no:
Chambered mufflers matter.:yes:

 

Just got off the phone with Thrush and he said "Nope cant do that only one you can do that with is the turbo muffler"

 

Got the mufflers with the correct flow direction and took them and the car over. He got defensive and said "3 inch exhaust will support up to 1000hp so a slight restriction should make no difference plus you guys got the wrong mufflers" I said "You had my cell phone number you should have called me before you put them on backwards" then the subject changed to a chevelle he had there and it smoothed over. I walked in the shop with him to give him my number again and the guy that works for him was talking to my dad and said "He gets offended and offensive about his work very easily plus I told him when he was doing it that they shouldnt flow backwards and he said it would be fine so I ended the conversation there so I wouldnt get in a fight with him".

Anyway he is putting the new ones on the right way today. Should sound better. The backwards 40 series was pretty quiet and we all know 40 series are not quiet mufflers! :no:

 

Just got it back. I knew X pipes quiet exhaust down some but I never knew that much! The new mufflers installed correctly sound a little louder and a hair deeper but over all not much difference in sound. I had 3" 40 series on my camaro with an H pipe and it was WAY louder. So the X pipe quiets it down quite a bit! At least I know the restriction is what it should be with the mufflers installed correctly. :yes:


Piss poor quality video and sound but here it is cruising home.

i have Super 44's on my '64 with an X (2-1/2" system). i have nothing to compare it too so i don't know if i'm loud or not with/without the X.

i love the sound when it's revved up and backed off :yes: :yes: :yes:

 

Mounting them backwards is only for SEDAN owners:devil::yes:

 

:yes: Because we all know sedan owners are backwards!
