Is that ABC bubble core dwv???? Good job on it, it looks good for your first pne, but try getting some pressure rated pipe. You probal could use but I think you should get SCH 40 pressure pipe. Good job

Pete Zaria pressure tested Cellular Core ABS to 100PSI and it held it in, combustions produce a maximum 50PSI. Your safe, if you want double check with Pete Zaria.

ABS is fine in combustions, its alot better than pvc too.
Its lightweight. doesn't need paint job, in my opinion its made with higher quality. And it doesn't shrapnel
