Emissions compliance question

[VSTNG]

During the process of discussing going true dual exhaust on my '07 V6, the person at the performance shop I was speaking with asked if I wanted to keep the catalytic converters in the final configuration. I was surprised by the question. I didn't know it could even be considered. He said they do not look. He said, if the emissions levels pass, then they pass. Should I be worried about "tampering" consequences? I live in Maricopa county, and drive this car every day. I don't have an option regarding annual emissions testing.

It is a Federal Offense to remove Catalytic Converters from a Vehicle that came from the Manufacture with them, there are ways around this though.

You could say you Car is "for offroad use only", remove the license plate, and send it to the shop on a flatbed truck. The shop owner then would not be legally liable for removing the Cats. Your Cats could have been "accidentally damaged on a traffic bump", in which case you are legally allowed to replace them with highflow aftermarket Cats.

The Shop owner is a business man who wants to operate within the laws (ie, no fines or jail), and still keep his customer happy.

IMO go with highflo Cats. they don't add that much backpressure, which BTW, aids lowend torque/bottomend performace, and you are legal. We all have to breath the same air too, and it is bad enough around here during the winter. Just use care around traffic bumps after you install them, woundn't want to have to replace those Cats again!

Well I would check and see what exactly happens to the system before you do that. The news cars all they do for emissions is plug the car in and checks the system, if by taking the cats off this trgggers a check engine light it will fail automatically. The they start checking all over your car!!!!

Thank you for that advice. Now I need opinions on the quoted price. From the cats back, replace everything (single manufacturer's '07 V6 exhaust) with the following: dual Magnaflow mufflers, dual resonators, 2 chrome tips. All joints welded. All labor and parts $650 at a Tempe performance shop. Seem right?

Sounds Resonable.

You may not want all the joints welded, it could cause problems in the future if you need to remove the tranny. Just a thought take it for what its worth.
