lol go listen to my exhaust video clip... thats what it sounds like if you replace the resonators on the midpipe with a straight pipe... :-P

 

Yes, a bit... but keep in mind, if you go with two 2.25" pipes from the cat all the way back in your car, you won't gain any performance... you may just actually lose some too. There is such a thing as "too big" when it comes to exhaust as well... this is something that Izero was trying to hit on earlier.

 

If you do a Y pipe after the cat and straight pipe it to the back N3ON then go to autobone or something of the same and get two 3.5" truck angle cut tips. I have one on my neon single exhaust with no muffler and the tip makes it deeper sound not ricey.

You can check out my exhaust if you want.

I am just doing a rough estimate but if you do a dual 2.5" from a Y-pipe right after the cat, it will essentially be like having a 5"-6" single exhaust... just an fyi... that is VERY BAD for our cars... you will lose your low end completely and you will gain power in the rough 8,000 rpm range... a point that our lil 2.0's can't even get to.... so if you want to go with a dual pipe setup like that you are gonna have to go for dual 1.75" pipes and that will still be pushin' it.... but it will sure as hell sound cool :-D.... what I've actually always wanted to do is make a different type of header that actually separates the two outer cylinders from the two center, so that they are two different headers, and put a turbo on each one... lets just say it would look freakin' awesome... reason I say separate the two outer cylinders from the to centers is b/c then you would have equal exhaust output, theoretically reducing turbo lag in a twin turbo setup... also decreasing back pressure b/c there wouldn't be a vacuum in the merge collector from the two cylinders that aren't putting exhaust out... I have a few plans drawn out but nothing 100% concrete yet... we'll see how it all pans out though... sorry for the thread-jack btw....

 

Nah, good info there. I didn't feel like typing that much earlier since you were already going there with the oh-my-god-thats-too-big pipe sizing for the exhaust.

 

izero would a 3 inch pipe be too big? But you cant really go to big with a rear section right?

3" rear should be okay... from the axle-back lets say. Just dont follow it all the way up to the cat... that would not be good, and you would probably lose a bit of performance if anything (larger area for gas to fill, gases move slower and cool down faster, become more dense before they exit the pipe, therefore creates more backpressure)

 

ok just wondering cause im gonna do a custom exhaust by the end of the year. So I'll keep the srt mid and lose the srt axle back.

 

Hmm, yeah that would work. I believe the SRT mid has a resonator in it, so it may quiet down your car slightly, but I don't think it will be detrimental to performance...
