Axle Back Tune Required?

[texag70]

Does an axle back exhaust such as Magnaflow, Borla, or FRPP require the car be retuned? I'm thinking since the original cats are still used this wouldn't be necessary.

No need for a tune.

Will Borla have an axle back for the 15 GT soon? Will you have it if they do?

 

[jayman33]

We will have it if they make them, I'm sure they'll offer one but they wont be ready (if they're available) at least for another 4-8 weeks.

I have a feeling, due to the fact you have to cut the system, that axle backs aren't going to be as popular.

If this is in another thread, sorry. Is a tune required for catback?

Your rear O2's will adapt over time but you'll kick a CEL due to O2 sensor placement more than likely.

Honestly, I would get a tune. Your car will run better and more efficiently. A lot of vendors in here offer tuning, I'd personally go talk to Lund for your tuning needs on the 15.

You need a tune for headers. There are needed vct changes that affect scavenging.
