First let me say I am aware of the benefit of using a straight through muffler and have run Magnaflow, Corsa and Borla on previous vehicles. Those usually cost me between 1200-1500 for a catback and I don’t want to go that route this time. I just purchased a 2020 with the 3.5 and want to replace the muffler only and leave everything else stock. My issue is I really like the sound of the Flowmaster Super 44 and 10 and have heard each in person but I know a chambered exhaust can have a negative impact on performance. The question is how much and would I notice if I keep everything else stock. Could anybody who has replaced the muffler only give me your impressions on things like throttle feel and performance feel after the swap.

 

I replaced just the muffler on my truck with a borla S-type. I think its perfect to be honest.

 

Do you have a sound clip? Thats the route i was considering. Also, is there any in cab drone?

 

Honestly I have found sound clips to be kind of meh, especially using a cell phone, go pro, etc. I can say this, it sounds great at cold start and when you punch the gas, and there is almost no drone at cruising speed. It has a WAF (wife acceptance factor) of 10/10.

 

Understood. What model number did you go with? I want to make sure i get the correct offset and diameters if you dont mind.
