should this effect the tune on the car ?

 

If you're asking if you'd need a new tune, no, you wouldn't. Axle backs don't need any sort of retune.

 

HxCguitars is correct. ANY work beyond the rear O2 sensors does not require a tune. But I'd search the forum for info before doing a delete. I've heard the tone isn't always pleasing to people. And FYI, losing the mufflers will barely gain you any power. The stock exhaust flows exceptionally well.

 

i have muffler deletes along with bbk shorties. the sound has a nice growl...

 

I had magniflows on mine and replaced them with just resonating tips and I am very happy with it.
