my buddy had a shop install an exhaust system on his truck a few months ago. well we hadn't been under it in a while. we were just under it the other day and noticed they were on backwards. what is this doing to his power gas mileage etc....?

 

What kind of muffler?

 

thrush something another same as the flowmaster 44 or 50 series

 

Are y'all 100% sure it's on backwards?

I'd think you'd be able to tell pretty quick if the baffles were backwards. Maybe not.

 

the outlet is on the engine side and the inlet is on the tailpipe side. seems to me like thats backwards

 

pics?

 

yes if its chambered muffler it will decrease exhaust flow.

no if its flow through design, performance wise shouldnt matter, but might sound funny


take it back to them and make them fix it for free

 

i might be able to he is out of state rite now though. im sure these things are on backwards

 

My cherry bomb glasspack is reversable, it doesnt matter which way you mount it.

thrush i think makes some like that.

 

as Patman03SprCrw said it is chambered. it looks just like my flow master i forget which one i have though

 

the yes you need to fix it.

theres an inlet and outlet for a reason. take it back to them, but be sure its backwards r you will look like a complete idiot. But i trust you know what you are looking at

 

there was a thread about this a couple weeks ago. so it is possible.

 

I had a friend who welded his super 44 backwards on his Lightning. When he turned it on it sounded a little funny, not as loud as he hoped. When he hit the throttle, it just shut down at 2000rpms, he figured it shut down due to the restriction because it's a chambered muffler.
