I may buy a used 16 this time around...so I might be screwed with a big failure this time. I'm guessing any dealership would be less apt to cover things so willingly if you didn't buy the car from them.

As for the catless thing I guess it's just a non issue in these parts. Not really talked about.

If you can find one that hasnt been altered in some way by the previous owner (hard to find), youre normally golden on a private or dealer purchase.

Emissions laws change all the time from state to state, so no surprise cities as yours arent as strict.

Aside from sound, did you "feel" a difference in previous header swaps? I didnt gain much on my previous mustang, then again they were shortys.

Looks like new car owners are good for 6 years now here - been a while since I read through emissions documentation - talk about Zzzzzzz.

Just be glad you dont live by Cali rules!

I did CAI, UD crank pulley and full exhaust with tune all at the same time. The car made 435 rwhp with those mods. Didn't get a stock baseline but average was about 380 for ls3 m6. Yeah it was a pretty dramatic difference. As far as just headers they were worth about 30-35 alone on the ls3 especially if you got 2 inch primaries (proven same day Dyno comparison by Ted). They are worth only about 20 at most this time around from results I've seen from others. Stock tri y better than ls3 manifolds not as much to gain.

Good info. By Friday will have my magnuson installed with all stock parts...sans a Borla axle back setup. Going to give it a year, then probably start ripping out additional exhaust that still retrofits up with my existing Borlas and keeps stock cats. AZ emissions is always a threat to get more restrictive.

Very nice. Plan on any track runs?

I got a ridiculous deal on a 16 SS. Picking it up Friday
