340 duster exhaust

[MyPlumCrazy]

Looking to change my exhaust on my 71 340 duster.
Currently have hooker headers and cherry bomb turbos 2.5 inch.
Think there is a leak .. what is a good header gasket.
Also looking for a little deeper sound. Flowmaster?
Is 2.5 inch enough or should I do 3 inch.

2.5" is plenty big, I love my Flowmasters and yes, they have a nice deep muscle sound....I have always had good luck with Mr. gasket header gaskets on my 340's :glasses7:

Just saw new product ad for Mr Gasket "Aluminum layered exhaust gasket" Leak proof. Seals warped or damaged flanges. Don't know anything about it, but looks new.

Remflex gaskets is what I used when I used.

I normally use Mr. Gaskets "Ultra Seals" but I didn't know they had that other one. Nice!

Deep throaty tone muffler? That would come from a chambered muffler.
Hooker Aero Chamber
Dyno Max turbo/Super Turbo
Summit turbo

Flow Masters do not flow as well.

Exhaust tune sizing should meet HP requirements of the engine and the cars performance needs. At 2-1/2 inch dual exhaust on the street (and sometimes strip) that would be very suitable to use.
