I made the block off plates with around 8 dollars in aluminum. I'm sure an exhaust shop could cut an weld them for real cheap.

No problem, I know a guy with a c6 that made 430+ rwhp with just your headers and a tune.

If the XSpowers release date doesn't hold true, I will wait until next black friday to pick up the PFADTS for sure.

I wonder if most inspectors can tell the difference between these resonators and catalytic converters???

Does anyone want to chime in? thanks

absolutely, they look night and day different

side note : aftermarket cats do not live as long as OEM and do not do well with rich tunes. they melt from gas entering the exhaust. OE cats resist this much better

These resonators are shaped like the cats and in the same spot as well. Normally I would agree they look night and day different, but not in the case of these obx header systems.

Heck, they wont pass emissions anyway, so it doesnt matter for me. I just thought they might pass the visual inspection. thanks
