I looking at two different options for the full exhaust I'm going to get. I'm also not particularly concerned about the price, I'll pay for either, I just want to get what's best.

Option 1) Vibrant 4-2-1 Header with Downpipe and High Flow Cat with the 3 inch Vibrant Catback

Option 2) SLP Long Tube Header Downpipe Combo with High Flow Cat, and 2.5 inch SLP Loudmouth 2 Dual Outlet Exhaust

My goal is to break 300 whp...so I'm figuring the 3inch is the way to go...I just love SLP's products because I used a bunch of stuff from them on my old v6 camaro

Lemme know what you guys think

 

V6 camaro > I4

slp sounds very very different on a v6 then a I4....

also what about the zzp combo

or the JBP header and random tech downpipe?

 

So why do you need a 3 inch exhaust to break 300whp?

You don't all 3 inches is really good for is noise or turbo cars

 

i would say slp based on the options, i have never seen a bad product from them.

I will be going with the clear image header, i think that because it is a 4-2-1 header, it gives you more useable power (not just top end), but like i said, you want peak horsepower, go with the slp.

On the other hand, the vibrant is a nice piece to...

Vibrant 4-2-1 Header with Downpipe and High Flow Cat
Corsa sport

Total with Shipping:$1,349.96USD


This is what i might be ordering as so as get some input from ppl on the Vibrant header / downpipe ....

 

I would go this option, but with the Corsa Touring.

 

When we are alredy on the topic all ppl with Vibrant 4-2-1 Header with Downpipe and High Flow Cat


Under the acceleration dose the cat make any noise
whistling noise or somthing like that

BTW i thing cobalt addiction has the best price on the

Vibrant 4-2-1 Header with Downpipe and High Flow Cat
Corsa sport


?

 

there is a thrid option you chould just get the header and dowpipe and have a exhaust make you a 3 inch exhaust from the downpipe back.

 

slp sounds like CRAP on the cobalt. worse than a honda with the 3 dollar ebay muffler.

 

lol, Ouch... BURN!!! but i kinda agree. I wasn't a fan of the SLP on the cobalt. Dosn't sound right

I have the Vibrant 4-2-1 w/ high flow ***** and Corsa Sport. I like the power... I do wish it was not as louad tho. I miss hearing my S/C scream

 

Do you have a VID?

PLZ


Thanks

 

IMHO the SLP catback sounds like someone cut off their muffler and let it go at that . I really liked my SLP loudmouth on my Z28 , but their SS/SC CB sounds like a straight pipe .

 

I had a three inch, I replaced it because the sound got to be too much, the drone is terrible.

 

Well the noise isnt a problem for me at all...especially because the camaro was ridiculous

but is the 3inch really to much...because i keep reading that basically after liek 260-270 wheel the 2.5 is too restrictive

 

dude just get the zzzp.... its soo nice!!!!!

 

there's a saturn motorsport's header DP with highflow cat combo for under 900..
and it work's on ANY LSJ...
http://www.saturnmotorsports.com/cat...roducts_id=756

 

why would i pay 900 for saturn motorsports when i can find vibrants for under 700?

I've been listening to a couple more clips...and im narrowing it down to the Vibrant, Megan, and Ark...any opinions on these (for the catback that is...since im buying that first)

 

That is a SWEET looking piece

 

well a becuase its equal length. and i mean look at it it's a ******* RACE header they sell at a dealer..
b becuase you can buy it from ANY saturn dealer which kinda makes it a GM part. which mean's THEY CANT give you **** for aftermarket header/highflow cat AND a cat back. i dunno if you care about warrenty but if they sell it at a dealer they cant call it aftermarket.
and also guess what? since it's an exhaust part you can put it on your self. and one more thing if you think you need 3 inch piping to get 300 WHP on an LSJ your wrong. you need a turbo. or jus about the cost of going turbo in supporting mod's to make the SC dailydriver friendly. jus my .2cent's and opinion. and iw as also letting you know that there are other option's out there.

2nd one sounds good at idle, till it revs high, and listen to the take off. talk about bees in a can

 

man i wasnt attacking you...sorry it came off that way...i was just asking why...so thanks for the realy great sounding suggestion

ok and so 2.5 is ok which is good too...gives me some more options

 

zzp gives you the most options.. any options you can think of really

 

yea i saw ZZPs also

I've been doing a lot of research thought and i think I'm going to go for the Megan Catback if i can find it...since thats the first step...header will probably be the vibrant

 

It's not so much the noise as the insane, resonance and drone that a 3 inch exhaust has.

Also you can get to 300whp without a turbo, it's call nitrous.

 

true but once you have the nos you need to have a way to monitor what's going on. so that's more supporting mod's.. and to the thread starter i know you werent attacking me. i was simply providing another exhaust option. may not have come across that way. i apologize.
