Hey, I’m new to learning about cars and exhausts so sorry if I sound dumb for asking this question. Why do you record every week? Does it change within time?

[zztop]

I’ve ran magnaflows my whole life but always without resonator. Been thinking of putting a 14” on my 18 with resonator in tact.. not too loud inside cabin is it ? I’d like to be on highway not hearing it

[anthonyvega]

Did you only get a muffler or the whole pipes done

Are some of these weeks warm starts? It sounded extremely muffled on week 2 then back to loud week 3.

Do you have an instagram that I can contact you through? Have a couple questions. Thank you.

Week 2 and week 4 were not cold starts, where week 1 and 3 were

Another exhaust video with only a cold start. Better to give it some revs so we can hear the rpm exhaust notes...

Flowmasters sound so much better on Chevys
