Is this muffler OK

Hi, I’m new here. I hope I can get some help from you guys. My car is a 91 integra LS-S. I have this Flowmaster muffler that came off a Mustang that belonged to my brother. He bought the mufflers and then decided to sell the car so he put the stock ones in. I have a DC ceramic coated 4-2-1 header and an iceman intake but stock exhaust. If i pu 2.5in piping along with the muffler, will I run into any problems? My concern is that the Flowmaster is smaller in volume than the stock muffler but has 2.5in outlets. Any info will help. Thanks

Most of the Flowmaster mufflers I have seen are not made for 4 cyl engines.

The ones I have heard on tegs sound like a pi$$ed off Bumble Bee.

Maybe someone who has installed one on their teg can give you a first hand report…

Thanx for the input. That is what I was afraid of; I was unclear about the noise they make. Lates.:confused:

dont do it!!! sounds baaaaaaaaaaad

The have a 60 series and the have a sound clip of on on an Acura Integra Type R.

i have a flowmaster knockoff , “raven” and it sounds real good not raspy just put a big resonator with it. check out one of my vids in the vid section you can hear it
