Hey all im looking for someone that make short mufflers? In all 12" or less with a 3" inlet and a 4" outlet. I have a blown small block in my little car and there is no room under it. I want to have them exit the rear of the front fenders like the promods..
You might try Porters. They are hand-made, and charge no more for custom sizes. Mine are 14". Maybe they can build what you need.
Google Speedway Motors and check out their Oval Track Catalog. Keyword: mufflers...and you will get pages of shorty mufflers built by Schoenfeld that are as short as 8".
Look at Supertraps "Shorty" 14" long. Saw them on a couple vintage Fords at Billetproof, Antioch, CA, couple weeks ago.
