I have same setup and never experienced what you described. I'd go back to whoever installed it and let them check it, something might be loose, not sure.
I have a 2025 Mustang GT base model, I’m trying to install a tow hook, but the location I’m pointing at in the photo (the plastic cover piece) is not coming off, i tried pressing it but nothing. Anyone knows if I can install it on the base model or not? If yes, how to remove this plastic piece?
Like:
Borla S-Type Catback + Borla H-Pipe
Stainless Works Long Tube Headers
High Flow Air Filters
Dislike: Carbon Fiber steering wheel with LED lights (I wish I got it without the LEDs, no one knows how to connect it in the S650s)
It does sound good and I get a lot of compliments, there is still some raspiness at high rpms which is fine but I lean towards the deep throaty sound lol
Yes, I've seen Steeda doing a dyno comparison and it's insignificant change in hp. I'll probably go with H-pipe.
Throwing a Whipple and a tune on your DH will make it a beast! go for it.
