Would Changing An Exhaust Mess Up A Tune?

[DonP 0]

I had my car dyno tuned.

Would replacing the stock cat back exhaust for Zoomers / Solo / or Magnaflow Competition throw the tune out and require a re-tuning?

I'm wondering if these aftermarket replacements flow that much better than the stock exhaust.

Thanks.

Save your money, cut out the bottle mufflers between the cats and resonators and replace with straight pipe. Any muffler shop can do for like $100 to 150. Sound is awesome and no drone.

Zoomers, ftmfw!!!! And yes it if you've done cam, heads and intake stuff. But stock, no.

Within the first two weeks of getting the mag I did rims, tires, tint, jet chip and zoomers. Then after I did the 6.1 conversion worked with frank to bring their 3" system to market. That original prototype still lives to this day on diboblo's charger and still looks great.

Yes, I know. But may car deserves a SS exhaust !

I've had the stock exhaust since new (2011), and I'm in no hurry to waste my money. I'm waiting for a good deal to show up if I do go for it.

But back to the original subject, can changing the cat back exhaust cause a big enough change in flow to require re-tuning?

I'm currently at 441 /446 at the wheels. Only mods are a CAI, ported TB, and 180 stat. And the dyno tune.

I did 12.373 at CF7 with stock Goodyears (255 40 20 rears). That was my first time competing.

Thanks.

Any after market cat-back, all you are going to do is change the sound, no HP gains and will not affect the tune.

Great deal, jump on it. I have the Corsa Sport on my Challenger, it screams like a banshee.

Thanks, but I think I'll try the muffler bypass first and see how that sounds.
