Stockers I see. Were you getting smoke at startup?

Ah yes, sorry. I was, as well as major oil consumption. Plugs and wires were trashed when we pulled them (had been a couple years since I changed them), so I'm hopeful that the tuneup plus valve seal change will eliminate the excessive consumption. I also purchased an ebay catch can, but haven't installed it yet.

Had the helmholtz resonator built / installed yesterday. It works awesome! No drone at 2k at all. Slightly less sound than I wanted below 2k, but I think the trade off is worth it.

I feel like it needs another hanger. Heimholtz resonators work thats why oems use em. I didnt see previous posts as to why or how it was designed on your truck whats the deets? Looks good. Stoked it eliminated your drone.
