Hi all,
I few months ago I had a flowmaster 40 series delta flow installed on my truck by Muffler Man. Yesterday I pulled the bed off my truck and I see that the muffler was installed backwards. Could this be affecting the performance of my truck? Or maybe damaging the muffler or cat? I can't believe it. I paid the idiots $200 to just clamp a few pipes together and they but the damn thing on backwards. I think I'm gonna go in there tomorrow and demand that they put a whole new system on and then refund my $200.

 

do it!!!!!!!!!!! thats y i do all my own lil work likr oil changes and exhaust

 

Mostly a mufler is directional for the sound, the way they do the baffles etc.... But I would go back and have them do it right.

 

With the delta flow baffles it could POSSIBLY be affecting the performance a little. Since they are in a V shape, with the point pointing forward, if it's backward you would get a reduced exhaust flow.

 

I talked to a flowmaster tech on the phone and he said that it could cause backpressure issues and lead to overheating. Do you think the sound will change once it's flipped around?

 

the sound should deff, change when if is flipped around. i would be rather pissed if they did that to mine.
