that explains a pulling a bit but not smoking it. then again i've never raced an auto 5.0 so i don't know how fast they are.

 

i find this picture to be both offensive and hilarious

i think i may have my heart set on just the catted dp/exhaust combo from turbo XS and see how that runs without a tune. anyone had any problems running for a whle without a tune?

also, would it be better to tune it here in america or wait until i go to tuner capital of the universe JAPAN next april?

WHEAT BURNER! WTF

 

Merica'

Japan tuning Di cobalts... Idk about that

 

my Hahn never threw a code and sounded sick...just sayin

 

i ran the turbo xs GT exhaust and the catless DP for about 3 months before i got it tuned... car ran fine. no CELs...


and only the hahn and the turbo xs catless DPs do not throw a CEL, mine never did, and neither does hahn's

 

if you want a specific sound, check this thread out

Honestly, dude, save your money. Most people that spend a lot of money on these cars either break them and sell them, or get tired of pouring money into them..........and then sell them, for huge losses.

If you're happy with your current power, leave it alone and enjoy it for years. An exhaust is going to gain you absolutely NOTHING but a different sound. A downpipe will gain you something with a tune, but not with just he GMS1.
If you're not happy with your current power, you need to set a goal of what you want, power-wise, then make a plan and get there. If you start throwing away money on stuff that doesn't add power or reliability, you'll never reach your goal.

Keep in mind: this is just a Cobalt. Modify accordingly.

I have only bought a ZZP catted downpipe, a ZZP intercooler, and the HPT suite and have been satisfied for years, now. NO issues, other than rear brakes, either. Running with the big-boys seems like a waste of time with a car like this. Have fun with it, but know where to stop before the money pit gets too deep.

 

dude... come on... you have never tested those statements before. and have no sources that prove you are correct...

that is complete myth on this forum... a 3" cbe does increase flow and does increase hp (something vendors have proved to be true)... peak hp is something completley different than midrange power...

i have full bolt ons on my car.. i even have a ..... do i dare to say it..... YES I DO! I HAVE A FRIGGIN' BOV! are you going to say that all cobalts with a bov have problems too?? no man... cmon

 

My bad, I guess spending $400 on a catback is a great idea if you want to gain 5 hp.........on the top-end.

 

for you maybe... but you also get 12-15whp midrange... and that to me is worth it

 

Tell me what a ttr rfl loud exhaust has on a stock exhaust with a muffler delete? .5 inch bigger pipe? Exhaust are a big waste of money. I can have a 3 mandrel bent stainless exhaust custom made for my car for 200. Yeah go ahead and buy into all the bs about how great a 3 inch exhaust is with no muffler. Let me guess, they use a super special metal that increases hp in the mid range? Hahaha

 

dyno proof sir?

 

ttr never made an rfl exhaust... or any catback exhaust for that matter...

yeah, you can do that. go for it. grab an S pipe too tho. and make sure it is free flowing and not restrictive.. and you got yourself a good exhaust... you might not get it perfect the first time tho..


my friend did this... sounded amazing...but didn't like it after a while... now he has a Turbo XS RFL exhaust

 

thanks for the suggestions this has been most informative and amusing to me. im kinda leaning towards stocking up on parts now and just getting them all put on at once and tuned.

just a cobalt?? meh. i suppose so but a man could fall in love with a pinto wagon, couldnt he?

 

agree'd i love my car. and that is a good way to go

 

I'm with padlock. I'd love to see that before/after dyno sheet.

 

My bad. I ment ttr sells them.

And what are you talking about a free flowing exhaust? Tell me how it could not be when there is nothing in the way to restrict it. You know the stock muffler is a straight through flow design with baffle chambers on the sides. The stock muffler isn't really restrictive too.

 

In4dadyno.

 

and.................I wouldn't hold my breath for that.

 

one last question, how much cash monies would i have to spend to make a reliable 350 whp?

for it to be "reliable" am i digging into building up the tranny and engine? like new rods and pistons? or mayhaps the stock stuff can handle it?

 

zfr

 

Stock internals and trans can handle 350hp but your knocking on the devils door for something to go wrong. You could make that power on the stock turbo with an aggressive tune and e47. You'll need a clutch soon after.

 

what internals would i need to replace, and further, what EXACTLY entails in building up a transmission? mayhaps there is a suitable tranny that will swap right in?

edit, sorry for the noob questions i only know how things work, im pretty limited in my knowledge

 

The lsj trans is what most lnf guys do when they turbo swap because once you reach around the 400whp mark( not saying its a for sure thing your trans will blow), the trans is the first to go. Internals should be fine for awhile if you don't beat the junk out of it everysingle day.

 

Op says he has done his research and wants to know whats the best header for a cobalt ss turbo....... Im guessing u didnt do any research on the ss turbo.
