Hey

I want to know if there is any Exhaust Manifolds from another Mazda vehicle that i can throw on my truck to replace my factory one? I basically want no Cat's, don't want a header. Looking to open the rest of my exhaust up at the same time, all the rest is 2.5" except the manifold n pipe coming off. thanks.

if u go through the trouble of changing it why not go header? emission laws?

Take the air tube off ur exhaust manifold,pinch the tubes from the cylinders off and weld shut,make a block off plate for the air tube going to the exhaust, take the #1 cat off but retain the heat shield to help engine warm up in winter.I dont believe anyother exhaust will fit other than the Pacesetter header.BJ

Use the manifold and down pipe off a mx-6.Cut maybe 3 or 4 inches down off the flang of the down pipe and have a custom exhaust done from that point

yea ive already got my exhaust capped with lugnuts, i have a weber carb. i think im just going to make a flange and run pipe off it..2.5"

i found out my secondary magnaflow was clogged because i was shooting flames out of it with the MSD soft touch rev limiter, so i know my primary must just be fuckkked

Looks like a kandy organic green over a coarse silver base to be... maybe even micro flake...
