F-1 Exhaust
Just thought i would ask... What size diameter pipes should be used with a stock 8BA? I'm using 1 3/4 and seems to me kinda small. I'm running a Smithy type muffler that exits just before rear end and it seems real quiet. Im not looking for the sound of a 500 Horse Big block ,just a little more roar!

Re: F-1 Exhaust
Dual 1 3/4 is good enough to let the motor breathe.
Soundwise bigger pipes and some mufflers will get you that low note sound. Its basicly about how many times the sound hits a wall and reflects so bigger space gives less hits on the way out. Then add a bit of damping to get the high frequency kept in a reasonable level. |

Re: F-1 Exhaust
1 3/4" are plenty big enough.
FYI, 1 3/4 straight pipes on my F1....... A little to loud so I'm adding 18" Brockman mufflers. If you are doing he work yourself try w/o mufflers before you weld it up if you want a little more rumble. https://youtu.be/mJIFf35IATk

Re: F-1 Exhaust
I have 1 3/4" headers on my F1 that empty into 2" straight pipes. I like the sound or maybe I've just gotten used to the rumble.
I have had two sets of modern Smithy's fall apart (daily driver driven hard) so I'm going without. |
