I currently have Hahn 3" catback but want something louder but at the same time to still have that intoxicating sound. So I'm thinking about going straight pipe but not sure which system I should get. I listened to a few on YouTube and found one that I like, there were quite a few that didn't sound that great.. Just sounded like a Honda civic with coffee cans on them. Here's a link of what I would like it to sound like.
Cobalt SS turbocharged exhaust (straight pipe) - YouTube

 

that's just a catless downpipe with the stock muffler cut off nothing special

Cobalt SS Turbo MPx Exhaust w muffler delete/no cat - YouTube

this is a clip of the mpx straight pipe (which i'm selling :-) the sound quality isn't that great on this clip but i just grabbed the first one it has a similar sound

 

I'm running a Straight pipe, just go to a local shop have them chop off your hahn muffler and weld a 3" pipe in place with a nice tip and you'll save yourself some $$

 

thats what i was gonna do with the mpx piece that i got off a friend
like i said not to ***** you thread but i'm selling it and suggested people do the same thing

 

Straight pipe sounds like **** IMO. Loud yes, intoxicating... no.

 

^^ I actually agree and I have it i'm looking at a Magnaflow race muffler to put on mine to mellow it out a bit
