well the subject is exhaust cut outs. one this type of car would they actually work. i tried on my truck and it was loud but awesome. the main question this type of engine does it need alot of back pressure or would you gain some extra hidden ponnies, because it would be sweet to all of a sudden sound super mean when next to some one.

 

I have never heard and open exhaust on a Cobalt so I can't answer for sure, but I am yet to hear a 4 cyl engine with open exhaust that doesn't sound like garbage. So I assume the Cobalt will be no different. I'm sure it will be loud as hell but will it sound good?

 

I have a cutout for my SRT4 and it rocks and sounds insane in person!

 

SRT4 cutouts sound so nice is person... you can hear the turbo spool its wicked.

 

I dont think the purpose of a cutout is for it to sound good, so who cares what it sounds like. If you take it to the track and open it up and it lowers your times, thats all I need to see.

 

Well maybe the purpose isn't to sound good but I hate annoying sounding exhausts. Now cutouts on an LS1, that sounds good.

Orlandoech: I have to admit your car in that video sounds very nice. I think turbo charged cars have a slight advantage when it comes to exhaust sound because the turbo quiets the high end of the exhaust a little so you don't get the buzzing bee sound as much.

 

Thanks! yea I have heard a lot of cutouts and some sound horrid... makes me wanna shoot myself when I have to hear them.

 

they make some killer electric ones now too. not sure about gains, but it would be cool.

What stops the exhaust from just following the stock piping too.

Wouldn't you want something that blocked the other way while opening the cutout for best gains

 

I have an electronic swtich in my car... I can open and close it whenever i want

 

most cutouts leak a bit. i wanted to ad cutouts to my 65 but my uncle said he tried them before and it kept leaking so he got rid of them

 

lol.... ITS A HUGE EXHAUST LEAK... LITERALLY!

 

no such thing as needing backpressure:P
