Not to get off topic or anything but why do you guys all feel you need a 3" exhaust system. 2 1/2" is plenty.

 

On my custom 3" exhaust I used a magnaflow resonator and a magnaflow muffler. I like the sound of it, mine doesn't have a cat so its insanly loud. It sounds good and at first it doesn't have any rasp, but after the muffler and resonator break in it gets a little rasp when its cold, but once it warms up the rasp goes away.

 

cuz im shootin for well over 300. and i want a nice deep tone

 

You can get plenty of power with a 2.5" exhaust system. Understand that your form of forced induction isn't reliant on your exhaust system. All it will do is shift your powerband upwards, kind of like what it would do on an naturally aspirated vehicle but I'm sure you guys have a stronger velocity than a n/a engine.

As far as a deep tone, you can get it with whatever size exhaust system...the diameter of your exhaust system isn't the only factor as far as sound.

 

cti offers a full 3 inch exhaust system with a choice of a dynomax or magnaflow muffler.

 

Well concidering the guys with 2.5" and 2.6" pullies start to loose power at around 6500-6700 rpm a slight upward shift couldn't hurt. Also I have yet to hear a 2.5" exhaust (on a ss s/c) thats as deep as mine

 

Wow...my thread was ressurrected....yeah my 2.5 is deep but not as deep as my friends 3 inch vibrant. Omg the vibrant is so sweet! I actually have a video clip of it on youtube...i'll post it

 

i did no know that power fell off so early with the 2.5s

Sound is only according to how the person designs their exhaust.

 

Adam, why do you always have to play devils advocate? lol

 

LOL cause you guys love it

 

Well, I have plans for my cobalt as do alot of ppl. Im going the full turbo way, and having the 3"in on there now, and not having to upgrade it later on jsut helps me now. being i have a lil more power, all i have to do later is cut the weld, Change manifolds and doeverything else u would have to do to bolt up the turbo.

 

Oh, well, in that case, more power to you, 3" is the way to go!

Good luck.

 

Thx, may i ask why ur up so late, or so early??

 

I work nights. It's what I do best (well, 2nd best...ladies growl )

 

lol, Nice. Im a night person as well. Just not a workin one. YET!. lol. but im 17, and a drop out. so that sux. but a friends mom is gettin me a job at the bob evans up the rd. so im kinda happy about that. have some cash saved up for the balt in the spring. Then, all hell breaks loose down at the cruise. Kids with Lil honda's be like, DAMN, lol and the kid with the "pimped" cavi. well be like, hes jsut stock, jsut has an exhaust. lol. Cuz im not tellin no one about my modding im doing and im goin sleeper look. so all they hear is the S/c hopefully T/C if its out by then. and if it is BOV. lol. and my body will be stock besides tinted windows and Neons. Im not one for Leds. i dont like the look of them. u can kinda see each lil light glowing on the ground. well thats how it is with my friends trans Am. But im still deciding on rather or not to buy a resinator.

 

Interesting...

Resonator for the win though.
