Just getting my 69 on the road and I need a completely new muffler system. I am going to go with flowmasters but would like your opinion on which one to run. there is a 30 series and a 40 series that they recommend, dont know what either of these sounds like. Motor is 400 horse big solid cam. thanks Clay

Go to the website below...They have soundclips with different car/engine combos. I have the 50 series/Delta Flow on a small block with headers and 2 1/2" pipes.

I love my set-up. You will get varying opinions on this one though graemlins/thumbsup.gif

2 chamber deltas are just too damned quiet
2 chamber regular are too loud to me
try spintech

I've been using Flowmaster mufflers for 15 years on everything I've owned past and present.I cant say anything bad about those guys.....but after hearing a couple of cars with those Spintech mufflers makes me want to try a pair on the old Chevy.

I use the 70 series on my 69 Camaro.But those are some big mufflers up under there.

I have 40's on my stock setup, 396-325, and I love the sound, pure muscle! My friend has 40's on his 68 ss350 with headers and they sound great as well! The choice is your's but many people I know say 40's are the way to go! Good luck!

love mine...got them at racemuffler.com :cool:

I have the Series 30 two chamber and think they are great. Now, my car is not an everyday driver and if yours is going to be then you might want to go with a quieter muffler. Mine at idle are very nice but if you put some "shoe" into it you WILL hear it!!!!
:D

Thank you guys for the feed back. Thanks mike for the web site for flowmaster that was very cool to listen to the different mufflers, My 11 year old son got a kick out of it !! He is a future drag racer and muscle car owner in the making. I LOVE THIS WEB SITE !! Clay

You may be able to hear my car exhaust note at my web page. It has 40 series Flowmasters, 3" to 2-1/2" Dr. Gas "X" pipe and Flowmaster 2-1/2" tailpipes. Haven't installed a radio on the car, just so I can enjoy the exhaust sound, it's music to my ears. :D

I just installed the American Thunder system from Flowmaster and it sounds great. The installation was a piece of cake too. Actually, this is the first thing so far that installed right out of the box just as the directions said.

I wouldn't pick your mufflers based on the sound bites on the internet. They don't sound anything like the car will in real life. Also, the sound bites don't capture the trademark Flowmaster head-splitting resonance because the cars are accelerating. How about a sound bite from the interior of a car cruising at 2200 RPMs?

I'll put that in schedule, it's a great idea! That way others can hear the music.

stay away from the flowmasters. Im running the delta 40 series through 2 1/2" dual exhaust w/ stock manifolds and a stock 350, and though they sound nice when idleing or accelerating the resonance at about 3000 rpms (which is right where I cruise at on the highway) is absolutely deafening, its an instant migraine. If you plan to drive this car often, consider another brand, maybe borla or dynomax.
