Dynomax exhaust?

[GunnerJ]

There is a guy with a brand new in box 4 inch exhaust setup that I might be trading for($200) trade value. How are those systems? Will it give new a noticeable increase in power? I'm currently running a completely stock setup. How much louder? Will I need to adjust the ip slightly to account for the added air flow? All help appreciated

which muffler exactly? What type is it?
While I have a diamond eye, it is a 4" louvered core (coveres open towards the rear/backwards), and man it sounds great.
Took away all the rasp my 4" straigth had (i am turboed), it has a very nice bark starting at 2200+ rpm. Sounds similar to a 6.0 exhaust note getting on it.

Doesn't matter either way, the day of the trade the guy texted me saying he sold it [emoji35]
