If your goal is horsepower, then no cat-back is the best cat-back, or for those who need to be quiet sometimes(or your puss ears don't like loud), an exhaust cutout is best.

 

I know OP and he wants the best bang for the buck. Basically what he wants is dynos of stock vs catback and sound clips for the best one.

He'll never run a cutout or no exhaust

 

 

DD not racecar

 

1. Cheap
2. Performance oriented
3. Practical

You may pick two.

 

Well I know I already bought one I was just saying what OP wanted when starting this thread.

 

I havent read through all the posts, so if im hitting a dead horse on this.. sorry...

to me, it should always be about bang for the buck... andto me a CatBack isnt worth the money for the minimal gains. why pay 400+ for a measely 10HP ( if you actually get all of that or not ) when instead you do stuff like tune or Downpipe since that's where the bulk of the money spent will actually yield results.

not to mention alot of those fart cans just attract attention.. sometimes unwanted ( for me that's important)

I remember some one on here saying.. if you're not making more than 400rwp, then a CatBack isnt worth it anyway.

so if you want to look good.. spend the money.. but in terms of "need" ... its a wasted effort. -- tune and downpipe takes you a very long way -- cause a clutch will be in your future soon after...and then a bigger turbo..intercooler.. ( and being broke alot )

 

I agree OP has tune and dp but needs intake and intercooler

 

It wasn't the loudness that was bad just the rasp sound.

 

This is the jackpot right here!

Thanks!!


Yup, I daily aprox 70 miles round trip five days a week;
I will compromise all out power for driveability, and reliability any time.

this is a contortion of the original statement;

it should read more like this:
"cheap" is a matter of perspective, as is "fast" (or in your case 'performance oriented');
As I see it, the Cobalt (to me) started out a a compromise car;
It gets great mileage for daily driving, and is fun, and has passing power pretty much when ever I want it...

As I see it, with this car, I have all three - because, in many circles this is already a cheap car - and we all know that there are many faster cars out there ~ especially in stock, or near stock configuration.

 

i open down pipe DD 25 psi e47 i love the fumes in my car and whenever someone gets next to me i give them the stretch and a blown ear drum

 

Those who say a 3" catback isn't worth it must be the people who don't have one themselves. I have an MPx 3" with resonator and muffler and it's worth it EVEN IF IT'S JUST SOUND ALONE. The fact that it may boost power a little bit is just an extra bonus. Gives the car more character and presence even if you aren't just going for volume. Plus from an aesthetics standpoint it makes the car look better, the stock tip looks puny. I will admit though it does drone a little on the highway even though it has a muffler, so that's something to consider if that'd be a problem. That could be because it's catless though.

Just my .02.

 

Except a cutout isn't a compromise of driveability or reliability. You just don't want one because it's too loud for you.

Despite what Magnaflow might say, cat-backs don't offer significant gains on these cars. If they admit that, how could they sell 3" piping to people for $900? It's simply bad business. At least other companies, like ZZP, are honest about the modest gains and don't rape your wallet in the process.

 

I love my zzp catback but I also have the 200 cell catted dp.
