I just got home from snowboarding and on the way home i saw this completly blacked out SRT4 on the highway. This thing looked pretty sick. Eyelids on the front and on the tailight. New Inter cooler so im assuming possible turbo upgrade. Gauges Galore and a really nice sounding exhaust.

Ive always wondered what the hell makes SRT4s little 4cylinder engines sound soo good with those exhausts. I personally love them. Sound way more like a v8 then anything. Can someone please tell what it is that makes them sound so good and backfire and ****?

I also wanted to know about dual for the cobalt...I seriously would probably neer get it but just curious. Do they make true dual exhaust for the cobalt? No just and exhaust that splits at the end to make it look dual. Theres a couple cobalts with dual andi think as long as you get the right bumper, its looks pretty nice. Kinda ricer but who knows. Anyone answer any of my questions that be nice. I love to have a cobalt that sounds as nice an SRT but also wouldnt do it just for that reason. If i really wanted one i would have bought one

 

im wondering the same but if u do put a cat-back on a cobalt it spits too, not backfires lol but yeah i was wondering this too

 

i believe they have no mufflers and jsut use resonators and it sounds like the from teh trubo? i dunno :P im a n00b

 

oo ur right they dont have mufflers

 

they sound like that becuse they are turbo'd, any cars exhaust sound changes with the addition of a turbo

 

Sorry, dual exhaust on a 4cyl = gay!

Get a turbo and an open, muflerless exhaust like the srt-4 has if you want a similar sound.

 

I like the symetrical look of dual exhaust but its not needed and it will just add weight

 

Yea i agree the whole concept is gay but it still looks good. But then again i think it looks good on all cars.

 

they dont have cats that why they sound so good Sti sound better then srt4

 

In pretty sure thats illegal in most states so i really doubt that

 

so what there basily like straight pipes sort of even tho they are curved. Lol Flowmasters?

 

yeah in most states my manager runs his Sti and his Evo MR with out them and man they sound mean. Never been pulled over or anything.

 

pretty sure they have cats stock. The STI sounds that way because of the Boxer engine. Srt4's dont have mufflers + turbo gives them their sound.

 

yea but you also cant just be driving down the street and notice someone is missing there cats. The reason is because you wont pass inspection.

 

the sound is from the turbo being in the exhaust loop....... to get this sound with a SC or NAget a wide resonator, i could help u guys out, dual outlets on an exhaust will help alittle too.... not alot but alittle because u will have 2 outlets makign 1 lower toned sound than 1 higher pitched..... the airflow will have a choice of where to go equalizing pressure alittle..... let me demonsstrate....

my low ass idle

short rev then rev to around 3k

the rev sounds like i revved it up to about 300 rpm rather than 3000 rpm but trust me its just that low of a tone, and the tone is only lower when under a load

 

yeah most cops dont care but he does get a lot of looks from them... when it comes to inspection time he just replace the down pipe with on that has a cat. He has more money then god so its not a big deal to him.

 

sti also has uneven headers except the newer ones.... notice the diff betweenan older sti with a new like 07 wth equal length headers, looses that choppy deep sound

 

why apoligize for your comment...cause its a crappy one? HTF can it be "gay"

 

yeah sti header on the older ones are crazy looking and a B***h to change

 

i think duals make any car look 100X better. I really dont know why it just does.

 

little confusing reading some of these posts. it almost sounded like cadet was implying that STi's dont have cats stock. they have to have cats to be sold legally here in the U.S. also flowmasters are not straight through

 

no they have them stock what im saying is when you remove them the sound is even better sounding

 

well of course, all you are doing is opening up the flow

 

i know a lot of guys with srt4 and sti and other turbo cars pull off thier cats thats why i posted that in the being bc i bet the one that 06cobaltss saw was catless that why it had that sound he was taking about. thats all im saying

 

yeah turbo guys loveeeeeeeee that extra flow, anything to improve lag time!
