When my GT was making a poping sound it turned out being the rack and pinion needed to be replaced. The first part we looked at was the control arm ( the cheeper of the two parts).
I was told by my warranty company that if the mod caused the problem it would not be covered. You might want to contact the warranty company to see what their policy is.
I was going to buy the prochamber, but after I drove a stang with a Bassani X I was sold on the Bassani. Did you go to mustangexhaust.com to listen to the diffrent setups?
My GT has been lowered and I like the feel of it. But it all depends on what you’re looking to get out of the car. If you want more power do the cam if you want good look and better handling drop it.
When I called the warranty company they told me that if the mod was the cause of the problem it would not be covered. I had my car in the shop to replace my leaking intake and the warranty company covered it. Who knows all dealerships are diffrent.
