Anyone in San Antonio, Texas???
 

I am debating an upgrade for my 2016 Corvette Stingray 1LT either:
American Racing Headers 17/8” w/ cats
think I’ll need a tune??? OR
Magnaflow Competition Series Exhaust??
Any thoughts?
Also anyone here know a good shop for the install whichever I choose?
Thanks in advance

BlackJack Speed shop on Huebner Rd. Ask for Glen.

San Antonio
 

Thanks

Anywhere else? Just to get variety...

Henderson Performance...www.hendersonperformance.com in New Braunfels, may or may not build/install an exhaust system....Can definitely perform a tune...Call them and ask.

Nelson Performance...www.nelsonperformance.com is another choice.

Thanks Wolfman

For clarification, the NPP exhaust has the shutters inside the pipes? So if there’s NOT any shutters it’s just regular exhaust??

Also, I just got a used 2016 Stingray 1LT A8T w/ about 21k miles on it & have noticed that when I’m on highway it stutters & hesitates on acceleration & or when I let off gas... any idea what on earth could cause this? No check engine light on or anything telling me something up....

There is a valve on the rear of the muffler at the exit pipe. Look at a picture on one of the for sale ads for NPP and you can easily see it.

There have been lots of problems with the A8 doing what you are describing. Look on the main forum and do a search. There is lots of info on it. Good luck.

If you are up for a small road trip, Aikman Performance in Cedar Park, TX (northwest of Austin) is highly recommended.
