Question About the Borla Exhaust

[reflexx]

since borla only has the axle back exhaust.. how would i get it to become full cat back? like do i have to get a custom pipe to fit it?? and anyone know how much that would cost?

much appreciated

You have to check your local muffler shops for price. It's pretty much a straight pipe from the cat to the rear axle. On the 2.5 it will also be a resonator delete too...I see your a 3.5 so you don't have one.

I have plans on getting a borla axle back and have a custom exhaust shop make it into a cat back. But I also want to put on a high flow cat, do you think it will mess up the O2 sensor any?

I don't think there is any wiring going to that cat on this car. If there is, I wouldn't swap it out for the minimal gains it would produce. If there Is no wiring to it, then you can swap them all day
