I just bought a stock exhaust manifold that i can use to port since mine is messed up anyways.

I think i need to use carbide dremel bits to port it but im not sure.

anyone got any advice?

im not looking for real power or sound gains, i just figure while its off i may as well try opening it up a bit. since the one on my car has a broken dp stud.

anthonyS88

how about you buy 6 studs and 6 bolts from ced and give me 3 studs and 3 bolts and you can have the manifold

Read title wrong... my bad.


Word of advice... carbide bits get clogged very quickly...
Use a drum sander and lots of 80 grit drums to finish it off.

i have a lot of the drum sanding drums, maybe i'll do that

carbide tips are what work best for taking off material. I never liked how well the stones worked, but you supposed to use them next, but i just mainly go from carbide down to heavy grit drums and rolls depending on 1/8" or 1/4" bits. Then to lower grit sanding wheels and then flapwheel (i usually stop there) and if you're really bored you can get some super fine polishing wheels and ****.

A professional rotary tool is recommended, i finally destroyed my second dremel cause they just don't have the power to grind for long periods of time. Plus 1/8" carbide bits take forever to take off material. I now have a bosch die grinder with both 1/8" and 1/4" collets, but still find myself in need of a snake extension that worked well with the dremels.

i got an el cheapo black and decker one, if i burn it up, i'll go buy another one. it cost only like 20 bucks.

dremel's suck you need an air drill to do it quickly.
