SPELAB 3'' Downpipe Exhaust For 2004.5-2010 LLY LBZ LMM 6.6L Duramax Diesel

Looks nice
Sounds nice
Pipie quality looks nice
Welds could have been better but should be fine
Tighten the hose clamps on the heat wrap before you install it they were loose on mine.

I went with the 3" down pipe as well as the lb7 style up pipe for my 06 lbz.
highly recommend the up pipe, much better than the block off plate.
paired with the 3" down pipe is a must, I can tell my truck is building boost quicker and getting the exhaust out faster.

Finished installing the downpipe last night. Fit Great, can't wait to get on the road and hear how it sounds.

Leaks/doesn’t fit on the turbo. Total junk had to buy a brand name. PPE and MBRP fit fine don’t buy this crap

So far happy with product quality

Down pipe would not clear the up pipe from manifold to turbo,had to use factory down pipe
