Hey guys, quick question. 2014 5.0L -----> If I install a set of GT500 muffs to a completely stock system, will I require a tune?
Gains without a tune?
I have a tuner for my 2013 3.7L but not yet for the coyote. Wish I could use the same tuner on both vehicles.

 

No tune is is ever needed for any exhaust changes after the cats.

 

This.

Side note, how's the new ghig going, sir? You ever miss your orange boss?

 

And there are no real power gains from a muffler change.

 

The tune will give you the most HP increase ... the exhaust system will provide minimal gains.

Let me know if you have any questions or if I can provide you with additional support?

You can reach me at tim@steeda.com.

Best Regards,

TJ

 

Hi, I'm really loving it, especially after all the mods to exhaust and suspension, thanks for asking. I'm ready now to make her faster, starting with a blower, or at least a high stall converter and 1-piece driveshaft. Here's a photo from yesterday's Steeda Stampede. Not missing the Boss at all.

 

Nice! Love those 302 chevron decals. Nice touch.

 

Thanks Patrick. I thought the satin black chevrons would compliment the GHIG.

OP, Sorry for hijacking your thread.

 

Hey!!!! That car next to you in that pic is a powdercoated blue Maggie blower like mine!!! Woooohoooo

 

He's hijacking the thread now. Jk!

 

Sorry. I got carried away. To contribute, no tune needed for cat back replacements.

 

No worries. Lol I was thinking about your car actually. I saw a shiny Z getting fitted with fancy tires yesterday. ...anyway... With the new SC, I bet you REALLY don't miss your old Z!
