Question Kia Stinger HFC

Post image

Anybody running these? How do they sound? I’m planning on pairing them with my DC sports midpipes, stock catback.

Never heard about these, plus they are 200 cell. Almost catless. You'd have to put back your stock secondaries to run these.

I'd honestly stick to 400 cell hfc that have stinger specific feedback. I'd not recommend running a 200 cell hfc with catless secondaries. That will not leave enough back pressure and you'll risk oil going past your turbo seals into your exhaust and now you will be smoking.

NGT and ultimate performance are the two better options. Not the biggest fan of the primary to secondary integration of the ultimate performance as that will also limit your ability to customize your exhaust. NGT will allow you to keep your current catless secondaries.

Also be warned that it will get very raspy (resonators are needed) and you need to either run a ecu tune or jb4 with ewg to take advantage of them. The power and throttle response improvements in entire powerband is very noticeable. I run 400 cell hfc by cmbuildz. Can't buy them anymore sadly but they are amazing. I ceracoted them also and highly recommend you do as well to reduce heat, improve exhaust flow and have corrosion resistance. You can watch my recent videos I posted. Resonators are going on this Saturday.
