check my sig for my mods, right now I have dynomax 1 5/8" shortie headers and 2.5" single pipe into a 3chamber
which was all put in back when I had a 305.
is it still sufficient for my new 350?
I need to get my exhaust fixed as part of the pipe is caved in when I put in the new engine and tranny. should I get 3" single and larger headers? long tube headers maybe?
or simply get the pipe fixed and call it good..

Does Dynomax make 1 5/8" primaries on their shorties? The last I knew they were 1 1/2".

well thats what I was told when I bought them from the parts man...
I'll go get my caliper

 

DynoMax uses 1-5/8" primaries, you're probably thinking PaceSetter. PaceSetter uses 1-1/2" primaries.

For the engine in your sig, your setup is fine. But I'd still get those dings worked out and if you want step up to a mandrel bent off the shelf 3" cat-back.

lost my calipers, so im not exactly sure what size they are..
I was told 1 5/8" but it doesnt say anything on the box it came with.

I was thinking of buying a premade system that I could hang myself actually, but i'm not sure how well those things fit.

 

I would go with 3" if I were you. It will flow a lot better. Just my opinion though.
