My new lowes sells 6" pipe, but i noticed it had a VERY low pressure rating, about 90 PSI. i was wondering how people make air chambers with this stuff wiout blowing up. i order to have a high pressure rating, i have to use shedule 80, which is, VERY expensive.

90psi is fine for a combustion

If you're wanting to have a big hybrid or high pressure pneumatic chamber then you're going to have to splash out for a higher rated pipe.

No sch40 then?

Hmmm... the stick of 6" I've got is rated to 180 PSI. Is your's SCH-40 or a thinner-walled variant like SDR-21/26/etc.?
