PPE or Stainless Works Downpipe

[G Kitsmiller]

Need advice from people that have made the high flow catalytic downpipe swap. Brand preference and why?

PPE makes great catted DPs, amazing build quality/fitment, and no CELs like some have complained about with Stainless Works.

I have had both and I recommend PPE. Fitment is better, actual cats work better, no CEL with PPE where SW did trip a code and still smelled. The PPE also totally takes rasp out of the exhaust if you decide to have a free flowing cat-back later.

I would also recommend you get the DPs Cerakoted from PPE as it makes a huge difference with heat and won’t bake your PTU, plus your ECTs will be happier. I ended up paying twice and sticking with PPE.

PPE, all day. For all the reasons above.

I have the SW and CEL are intermittent on my 2016. Biggest gripe is not being able to remote start when there’s a CEL. On mine, the o2 sensors are rotated, which is a pain in the butt to get them on and off and to secure the wiring away from the pipe.
