OK so i have a 94 4runner SR5 4x4 3.0 A/T.
Im thinking about putting all new piping (mines all rusted) removing the Cat. (i live in SC and theres no emissions reg's) and putting on Flowmaster Super 40...
Yay or nay?
any suggestions that i might have missed?
thanks...

i woudint remove that cat unless your replacing it with a hi flow one dont go to big on the pipe 2.25'' is fine as for the muffler should sound good and be plenty loud

Yea go with a high flow cat if replacing everything, its going to be super loud if u go with the flowmaster 40. It all depends on personal preference if you want it loud or not. I put a magnaflow on my 22re and its got a deep sound, nothing loud at all you cant even hear it hardly in the cab...I like it. But if you do decide to take the cat off...just straight pipe it...lol I had a friend straight pipe his 22re,...and it sounded like a tractor....talking louuuuuud!

Keep some kind of cat. I'm pretty sure the air in S.C. moves around freely like all the other air in the world.

firstcar4runner

the air moves just fine. lol
but we have no M.E.E. (mandantory emissions evaluations)
or vehicle inspection permits..

the highflow cats cut back on that rasp sound u here on the rice burner cars in town.a high flow cat and a 40 series is whats on mine and i really like it way more than when i was straight pipe and when i went just 40.my buddy owns fortuna muffler so we use my trucks for test.one thing straight pipe all the way back sounds good on is my 89 f350 with a 4600.sound like a pissed off bear.

sloppy85toy

oopps 460 not 4600 my bad.

I just hollowed out my cat. Now it's just a straight pipe. Illeagal but more torque and gas milage.

This is exactly what I have on my 84 22r. My exhaust pipe is 2.5-inch, I think. Maybe a little loud, but not obnoxious, with my high flow head and 261 cam from engnbldr, almost sounds like a V8.
