Up for sale are my low mileage (~3,000) AP headers with catless mids, which were installed on a leased car. For those concerned, it's a completely "bolt-on" setup with no cutting or welding required (they mate to the stock resonator unions). Although a tune is advisable to optimize the additional flow, it's not required, i.e. they're engineered so that no codes will be triggered, and our ECU's are intelligent enough so that a lean condition is precluded (according to AP/Vivid and other vendors).

While cold starts and WOT runs are loud, they can be driven very civilly (without additional noticeable sound), under 2k-2.5k rpms). Above that, they sound is euphoric. The vides available on youtube rarely do them justice. Those who have fun catless headers can attest to that!

Price is $1875 shipped (within the contiguous 48 states), and they're boxed and ready to go. I'm about 90 miles north of LA so a local pickup could be arranged for a price reduction as well. Excited to pass these along so someone else can enjoy!

And as my first post, thank you to everyone for the knowledge. I've honestly learned so much, and all my questions have been answered just by reading and using the search function. Thanks for doing all the legwork for me haha.

Hey Jayson,
Congrats on the new car. I'm only selling the headers and midpipes, which delete both the primary and secondary cats. Regarding the ECU, while a tune is recommended to fully utilize the flow improvement, there will still be noticeable gains with the stock tune, and no DTCs will be prompted, in addition to sounding incredible. In fact, I ran the headers/mids as a standalone upgrade for approximately 600 miles before purchasing a tune (Weistec Stage 1, which is I'd highly recommend if you're in the market, especially being so geographically close). PM will be sent shortly for additional info.

what are the gains with this?

what kind of mufflers did you have?

MVG

I didn't dyno the car with this setup but, qualitatively, there was a tremendous seat of the pants difference, especially at higher engine speeds. Also, you feel way more in tune with your engine given the auditory feedback. Perhaps someone else can chime in with some numbers.

I retained the stock resonator and mufflers, basically everything downstream of where the secondary cats used to be.

are they Long tube headers?

These are the units (not the exact ones I'm selling, obviously). Hopefully it's permissible to reference a supporting sponsor's website.

How can I dance around that can of worms? Short answer, yes, but but by the strictest definition, they're considered a midlength, as the final bend takes place upstream of the collector.

Bump! Boxed up and ready to ship out. Someone take advantage of this!

Just a refresher.
