Hi,
I have a 4.9L engine in my 1992 STS. I want a nice deap throaty muscle car sound that is loud when accel. I was thinking of getting just the plain series 40 but I think those will be way to loud inside the car so I think that the Delta Flow ones are better for me. Does anyone else have these mufflers? What do you think about them! Thanks!

i had a flow on my 4.5, but i think its a 50, its pretty quite but has a nice sound.

40 series the classic flowmaster ? think ill run 2 of them like the northstar deliives , now i need to find the oem style n* tips

then all i need is a set of concourse rear skirts to modify

Hey I have these mufflers on my 94' eldorado...4.6...dual...40 series delta, with 2.5" all the way back. The thing is very nice, well worth it. Im gonna warn you though, it will set off alarms and keep everyones attention :)
