Selling because I already have resonated fast intentions catback, want to go with a non-resonated hfc instead for more noise, Get it at a discounted price RIGHT NOW, don't have to wait 4-6 weeks from FI

Won't these throw off CEL lights? Do you have the O2 bungs or whatever its called?

Also, I have TopSpeed axleback with megan racing y-pipe. Will these still fit?

I had no CEL with my set. Also it will still fit

No check engine light, these are 300 cell so they wont throw a code up

Please close thread, I actually preferred these over z1 hfcs even tho theyre on the quiet side.

Im going to put them back on
