I'm trying to find out what would be the best for each piece to put on the 2.4 (pretty much all stock). Plz post what is the best and why if you would.

 

zzp combo

 

sorry but there is no clear cut "best". Some pieces work better with different set-ups. Do a little research you'll actually learn something.

 

What's the benefit of a catless dp vs one with a cat?

 

it will make maybe a 1hp difference without the cat. nothing that you would notice though. get a cat so it doesnt sound ricey and annoying(unless that is what you are going for). oh and if you have emmissions keep the cat so u pass.

 

Now my friend was telling me about high flows cats, what's the difference between that and regular cats?

 

The high flow cat.......flows more. Just like the name says. (basically it's less restrictive than the stock cat)

 

on a 2.4... i wouldnt go long tube headers, its a waste unless your going turbo. dont go zzp midlength or vibrant etc. i know the zzp has nice pair of stainless shorties that i would get

 

whats wrong with vibrant?

 

see sticky

 

nothing is wrong with them didnt you see what i wrote??? i said long tubes and midlegths. im pretty sure vibrant makes a midlength...

 

No way he should make another thread

 

is long tube really overkill for 2.4? i thought it still helps out throughout the power band more than midlength and shorty

 

Doesn't a turbo manifold replace the headers?

 

yes it does

 

yes, yes it does.

 

 

midlength is geared toward mid range and top end power.. frankly i think it's perfect for a 2.4 .. i love my zzp setup on my 2.4.. shorties provide low to mid power and full long tubes ( like the weapon r) supposedly give the best full powerband gains

idk .. i guess we'll only know when i get tuned and dyno'd or something.. it's really hard to make a test unless illmatics and i dyno on the same day since we'll be tuned by the same person .. and he has a short header and i have the midlength it'd be as close as you can get i think

 

BTW catless is illegal in some states

 

Wait, cause you said long tubes are useless unless it's turboed.

And with the long tube headers on the mod list there's only 2 different kinds- Weapon R Race Headers and JBP Vortex Headers- are either of these good and are there any others?

 

hey man if you want to see how my setup is at the meet i can take you for a pull or 2 (you're coming to the meet right)

 

isnt the ca v1 a shorty? or mid length?

i would do the ca v1 with the xtc downpipe and instead of going ***** out on a 400+ dollar cat back just get a high flow resonator and muffler and have a muffler shop switch the 2.25 second of ur exhaust to 2.5. will cost u around 200 bucks and get equal if not better gains.

 

meant to say super. my bust

 

cti sells an axle back weld in setup

 

so far i have the down pipe with high flow cat from Cobalt-addiction, and the GM Performance Cat-Back for my exhaust and i have a header coming in which i beleive is a CA V1 header from cobalt addiction. Even without the header right now it sounds nice. Its like a low purr when idling and then when you take off to race someone it sounds mean. Totaly nice if you want your car to be a sleeper on not make lots of noise.
