X-Pipe and High Flow Cat Installation Costs? Tune needed?

[BlkCamaroVert]

I want to get high flow cats and x-pipes installed in my 2011 SS. How much should the installation cost be if I supply the parts? It's stock except for Flowmaster mufflers and K&N CAI. Also, would it cause enough changes that I would need a tune or new O2 sensor?

Might as well do the headers too and then tune it.

no tune...for me around 850 for both installed.

That was just for labor? Did you need a new O2 sensor?

Take the 850 get headers and a tunner for a bit more and do it yourself. A couple hours of your time and you will have more horse power and better sound

OP-you have a convertible. Are you aware that changing the mid-pipe will probably foul the vert's chassis bracing? When I was researching headers for my vert,I ended up leaving the OE H pipe in place so that i did t have to buy an aftermarket brace. IIRC, ARH's brace was $475+labor.

I got a very nice result with ARH headers w/HF cats into the OE mid-pipe and NPP. Plenty of power. Sounds just right (you know it's modded but not obnoxiously loud).

And you will want a tune just to make sure your air/fuel mixture is spot on. Do a ported throttle body while you're at it.

700 hundred for the cats including install. Sorry that should be $950. The x pipe was 250 installed. No sensors needed. Op the solo hi flow cats will give you better sound then headers. But long tubes with a tune is a good choice also.
