no aftermarket exhaust is going to be as quiet as the stock NPP. i have 1 7/8" headers with hi flow cats to flowmaster American thunder npp mufflers. it was slightly louder then i liked so i had some https://www.summitracing.com/parts/xfo-ct04-14s put on. i think that worked. I havent driven the car sense I had it done as it has rained every day i have had off in more than a month. videos dont do it justice. it quieted it down to were the voice commands could understand me
