Re: [Amc-list] 258 Exhaust/muffler sizes

[Frank Swygert <farna@xxxxxxx>]

I'm with Mark -- 2.25" single exhaust is fine! That's what I run on my 280" stroker (4.0L w/258 carnk/rods). I removed the Dynomax super turbo though, and replaced it with a generic 16" turbo muffler. About the same sound at idle, much quieter driving down the road! The chamber type turbo mufflers (similar to Flow Master) are just too loud at speed! The generics have just enough fiberglass packing around them to mellow them out. Now I can hold a conversation AND listen to the radio, before it was one or the other! 

I run a 2" exhaust on my Jeep J-10 w/258, 4.0L head and exhaust manifold, Clifford intake, and Holley 390 cfm carb. Also a generic turbo muffler. Sounds nice. The 2/25" pipe is louder on the Rambler, but part of that is the larger engine.

I can say if you go over 2 1/4 you may  want to get a fairly stockis muffler to keep the noise down!
I run 2 1/2 on mine and actually have a glass pack under the rear floor acting as a resonator before going over the rear axle to a Dynomax super turbo sitting in the stock rear position.
   Either muffler on it's own was too loud for me with the 2 1/2 pipes.
