Cat-back and resonators

[Jay Dee]

Hello all. Does a catback exhaust remove any factory resonators in a 2011 mustang gt automatic? I had a 2015 mustang gt auto and removed the resonators with straight piping and just put axle backs on. Not sure about the 2011 setup?

07 Roush,

Nope. The resonators are in the tail pipes (from the mid-pipe to the axleback joint). If the previous owner installed over-the-axle (OTA) pipes then the resonators are gone.

HTH,

On a 2011-14 catback setups will remove the stock resonators because they usually come with their own over-axle pipes.

Thanks, Wolf302, for correcting my bad info (blush, blush).

Jay Dee: Sorry, I misread your post and was responding about axlebacks, not a catback. No resonators on the OTA pipes in an aftermarket catback.

Gotta go to remedial reading class now...

Here is a photo of my turbo car that retains the stock mid pipe section (with the resonators) after the stock "X" merge. A catback would eliminate this as stated because it would bolt after the cats and go all the way to the back of the car.

Thanks all. As stated above I'd plan on putting on a cat-back. Now, let me ask this. I don't want to put on headers, but I'd like to find a midpipe that has high flow cats to update the factory cats. Everything I've found requires the addition of long tubes with a high flow cat setup. I did find one that was magnaflow high cats with tru x setup but it was like $1500. Is there anything else out there?

Jay Dee,

You've probably looked at header kits.

An option is to keep the stock manifolds. In that case, we MRT. They make catted H-pipes for the factory exhaust manifolds.

If you're set on headers then JBA and Kooks offer high flow catted mid-pipes but, as you noted, they are pricey.

Probably not news to you.

Like a lot of things the prices of headers and mid-pipes are much higher than they were 3 or 4 years ago. Aye carumba, as Bart used to say.

HTH,

Chris
