ACM OEM Exhaust Mod

[MrStinky]

Had this mod and drone is severe like ever other race muffler

Does this mod cause any check engine lights? Does the reduced back pressure cause any significant power losses?

Thanks!

Nope and nope. All of compatible. Gives you sound and minimal to no performance gains.

Do you think the gintani race exhaust is louder than the ACM mod? If so, how much louder?

Does anyone notice that with the ACM mod, the car is less jumpy in torque within the gears? I know most people said they did not lose torque.. But I am wondering if it changed the characteristic of the car when revving to 8 grand and letting go on the throttle. Was the car more jumpy or was it less jumpy? On my previous NA car I felt like I loss low-end torque when I did a muffler bypass.

i got this done, at WOT theres no power difference. but DD driving i defiantly feel less torque off a dead stop.

How about when you are revving through a gear, like give gas and then let go. Is the throttle response less punchy compared to before?
