Flowmaster Flowfx sound on 340

[A Body 440 WHY NOT]

I put the same flow FX 3” on my 440. they sound great on your car. Can’t wait to fire mine up and break in the cam. My set up is shu Tri Ys. 3” pipe to 3” FX’s and then dump. Should be FINE

Make sure to post it! Would love to hear it on a 440. Going to sound pretty beasty with the 3 inch probably. Especially with the Tri Ys.

Ryan, it is on the way still. However, USPS is still slow to catch up from the Holiday Rush.

Just decided to post the sound of these puppies idling. They have that typical straight through sound, with a sound level of 83db at idle, measured 25 inches away from the tailpipes ( recorded on google pixel 3 XL, sound meter app). They drone at cruise but not as bad as the 40s I had. Those were good times though. The car sounded pretty rowdy at 750rpm, but the T-slots were completely covered (also maxed out on secondary adjustment).

'69 340
-x-heads 2.02/1.6 valves
-Keith Black hyper pistons
-purple shaft 284/484
TTI headers + H-pipe + tailpipe (2.5in)
- Flowmaster Flowfx straight through muffler (2.5)
-LD340 manifold
-Holley Brawler 750DP (stock specs but 3.5pv)
-msd 6al
-msd e-curve distributor (14/34, all in 2500).
-autolite 65 (.044 gap)
-idle speed : 900rpm
-sound DB at idle, 25 inches away from
-tailpipe: 83db

Sounds good. Love the cam lope. Ive been a Flow Master fan forever, not in a daily driver though. My 68 Notch is for fun so, the louder the better!
