Ok so if you are taking. About super turbos, I had them on an e body and maybe was what I had on the last 69 rr. They were what I’d call a generic street performance sound. With the heat riser blocked, they drone around 2500 rpm. You might want to run some sort of little resonator. I had an x pipe on the challenger, an h on the rr.

I’m thinking of getting repop hemi muffs from accurate and running factory style resonators to factory style tips on the GTX. I’m tired of the ca turn down bs.
