Help me choose a muffler for my 4cyl vehicle

Turbo cars are generally quieter than s/c and n/a setups. I don’t doubt that it’s quiet and civilized on your car, but on the Cobalt it sounds like shit and is LOUD.

do a dynomax or vibrant … good to go

I’ll try Dynomax if adding the missing sound deadening doesn’t help fix the cause to my liking.

Entire exhaust made of resonators… do it.

buschur bullet

if exhaust is too loud then you are too old and its time to trade in your car for a prius and call it a day lol

just kidding but seriously the cobalts come with stainless factory exhausts if memory serves not sure how that is crapping out on you so fast if that is the case. the black stuff you described early is just carbon and moisture in the exhaust and shouldnt really do any damage at all besides looking ugly as long as your car is not pooping fluids which I doubt it is due to its young age.

What is on yours?

Want to drive my hatch? Just a few miles, you will agree, too loud. lol

The muffler is aluminized steel.

agreed

I actually build these types of systems on the side. Sales are slow so I have plenty in stock: LMK

I lol’d.

ha^ha this threads too long id say just wear ear plugs while you drive

Apexi WS2’s are almost too quiet. One of those could work well with a glasspack on the midpipe. A bit pricey though.

Or get a dynomax.

I’ll be sticking with the factory unit, thanks.

buying another factory unit?

I should. It’s definitely gotten louder over the past week.

It’s not really loud, but the drone on the highway sucks. I was thinking about adding a side branch resonator but I really, really don’t have the time or patience to screw with this car’s exhaust any longer.

That’s because you have a 4.05 final drive and lack a 6th gear.
