80 series vs other flowmasters
i have an 80 series flowmaster muffler. it sounds pretty good. i was wondering how it is compared to the 40 series. my 80 series with no cat and large 4"X about 20" tips is as loud as a 97 lt1 with a 40 series, dual cats, and no lage tips. my 80 series may be a bit louder.

i believe the charts reflect tone, and not sound level. i frequently hear people complaining about the 80 series being too quiet....so i wouldnt think it would be the loudest one they make.

One of my buddies had a 40 series Flowmaster on his 1992 Z28 5.7 L98.....I swear..it wasn't just a little louder then and 80 series..I'd say more like 3 times louder. It sounded freakin awesome though....loud through every gear.....it would drown out the stereo system in it. I've been thinkin about getting rid of my 80 series so I could get a 40 series....

The 40's sound way different.....like 3 times louder....now on idle.....the 80 series sounds louder.....but when you get going down the street....you better watch out.....cause it's loud. I'll see if I can talk to the guys at the muffler shop to see how they made 2 tailpipes functional on the 40 series....it was like a dream come true....having 2 tailpipes that were both functional on a 40 series flowmaster....

Id love to see some pics of that hope you can get the guy to tell you how he did it...
Im thinking about doing that to my 98Z28 using my stock pips and just welding in a 40 series i wouldnt mind having one fake pipe cous the sound will more than make up for it .

i think you can get 40 series with dual outlets. its the delta flow 40 and i'm not sure how it is setup but i know you can get them in 3"in 2.5 outs and 2.5in and 2"out. i think they might be in on one side and 2 outlets on the other side. what about big block mufflers? do they make them with the dual outlets like the 80 and how do they sound?

I like my buddy's 40 series flowmasters than my 80 cause the 40 has a deeper sound while the 80 sounds like someone driving around with rags in the pipes.

my exhaust guy told me that the 80 series had alot of turbulence in it and alot of backpressure resulted from it. He recommended 40 series just cuz of the flow characteristics

I'm running a delta flow 40 series, mounted sideways with a turndown, 3" in, 3" out, with not cat and headers... it's got a beautiful rumble at idle, and when you open it up, it screams, no, I should rephrase that, it bellows! I love it! So far, (just got it all together)everyone that has heard it has fallen in love with it. I've only ever heard one 80 series on a third gen and it was on a nearly stock 305, so they're not really comparable, but sound levels aside, I like the tone of mine much better.
