Make sure you listen to a car with this setup first before you do it to yours. Maybe in conjunction with a rear section mod it would sounds better.
I hope you're doing well! Thanks very much for the feedback - I appreciate it. I definitely won't do anything to the exhaust without listening to it first. I'm still leaning towards the OEM Exhaust Mod (non-perforated) based on my research. Thanks again.
