The ZZP midlength combo or a badmab header and the 2.5" ZZP downpipe are both solid setups.

KN is a good CAI and it sounds good. Thats why I said try porting the LE5 TB, but still the exhaust side is where the restrictions are. And a legitimate tune from someone will get you some good gains with your bolt ons as well...not jet chips.

 

True ALL of that!

Porting makes the whole larger in diameter correct? what would that run me on a guess.. and mhmm ok just which is better and with no raspy loud terribleness.. haha

 

Yeah...NM on the tb port if your not doing it yourself...stick with your bolt ons and a tune and you'll be very satisfied.

The exhuast will not be raspy unless you get a catless downpipe. With a 2.5" catted downpipe it will sound very good.

 

One of these days ill post a video of my exhaust.... I love it.... damn near as quiet as stock... but much higher flowing.... It was quite loud before my trifecta tune... not sure what the tune did to quiet it down... but its almost too quiet for how I think the car should sound with the added hp lol.... and its my understanding that a good hp tuner can net you more hp.... but for reliability, I understand trifecta to be the better option as mine is my only car and a daily driver I put a lot of miles on

 

Not to be a dick but this is pretty speculative. The reliability of a tune does not depend on the software tuning it, but depends on the tuner and how aggressive/precise the tune is. For example I believe HP Tuners would be the better tuning software for our cars because a wideband can send information to the program, while Trifecta does not have this capability with our car. Therefore the HP tune could be more powerful but also more accurate/ reliable than a comparable Trifecta tune.

 

Get the Injen CAI. It can be switched to a SRI if you ever want to, since you are in Florida that could be a possiblility with all the rain you ger. Get the hydro shield too. Definetly get someone to tune you with an hptuner. Don't waste money on that POS jet chip. Since you are staying NA get a mid length header and downpipe, stay with 2.5 inch. Magnaflow is one of the louder mufflers, so I would get something else if you want a full exhaust, or stay stock on that portion, or switch to the ss/sc/tc axle back. Get a TWM short shifter if you dont have one yef, they are awesome! unless you are auto, cant remember if you said.

 

yeah I wouldnt trust myself doing it.. ha I KNOW i would mess something up and yeah I would be catted.

DO IT!!

I checked with Ingen and and there's fit 2.2's would that work on my 2.4? and where would I get a hydro shield? is the SS/TC axle back larger at all?? I'm auto haha

 

Yes the one i have was meant for the 2.2 works just fine injen that is.... google shopping for hydroshield

 

Best combo:

Any Intake (even ZZPs intake tube is good)

LSJ TB with adapter

ZZP or badmab header with ZZP 2.5" DP (this doesnt increase sound that much - idk where youre getting that from)

Stock catback

 

haha ok

ok gotcha

 

Bump.. check this out.. He has a 2.4L with magnaflow 2.5 inch axel back, ZZP 3 inch catted downpipe, and a BAD-MAB shorty Header with a 3 Ince Collector (what is this??), no intake. and it sounds like this...

Starts at :14sec
revs at 1:22

Does it sound like that cause of the magnaflow or the headers/ 3"DP??

 

riced out lololololol

 

haha yeah I dont like this all that much...

 

yeah 3" dp is too big for an le5 motor and the magnaflow is just loud and ricey sounding

 

i feel bad when i hear a cobalt exhaust sounding like that ;( my friends ss sounds like that but i think he doesnt know....

 

LMAO


and...
I think I like the idea of a badmab header(looks good) forsure but the ZZP catted DP is a magnaflow highflow... so idk and keep my stock exhaust. Anyone have a 2.5 and want to share some sound info =) thanks

 

ha and uhhh...

its hard to make a four banger sound good at high RPM.. if not impossible..

 

dont listen to these guys... I put one of those electric superchargers off ebay on my friends 2.4SS and it picked up a TON!

 

an electric SC??

 

Here is mine and its a auto. Injen, bad-mab, zzp 2.5 catted, custom Magnaflow exhaust

I like!!! watcha mean by custom magnaflow?? and whats your results?

 

Axle back. Got it done at the exhaust shop that my buddy goes for everything. Cost me like 200. The dyno was bad. They couldn't figure out so much ****. They had a cobalt fully bolted on a 2.7 pully only put down 260. And another with just a intake put down 238. I got 134whp 129wtq. Without a tune.

 

Nice and yeah something was definitely wrong with the dyno for that low

 

260 whp with a 2.7 on gas sounds about right, and mid 130s for an auto sounds about right also. Why do you think there would be something wrong?
