2.5 or 2.25?!?!?

[uberSC2]

I am gonna be doing a custom exhaust and I was wondering which was the best for performance...i also have a cai and a 91/92 header on its way and I plan on turbo.....but i hear the information about backpressure not being an issue...so i dont kno whether to get 2.25 or 2.5 and which would be more efficient and better for setups and such

[d3ad1ysp0rk]

Whether or not you plan on going turbo, I'd get 2.5 if I was buying an exhaust. That is, unless you could get a 2.25" for a really good deal.

Just so you know, if you're going turbo, your header and CAI will be useless, so you're just wasting money.

Also, make sure you throw a nice long resonator into the mix so it doesn't sound like shit. [img]{SMILIES_PATH}/biggrin.gif[/img]

n/a 2 1/4, turbo 2 1/2, bigger turbo 3

if you plan on boost, dont mess with exhaust till the time comes.

yeah...well i am goin 2.5 straight from the cat to a series 40 magnaflow...so i dont think it will need anything to make it not sound like shit....i kno all the crud im droppin in is waste of money but it will net for a few horses and it will make me happy for the time being...yay for poor college student....the meat of the plans are years down the road....but i think the 2.5 will be the way to go....by the time i go turbo i will be dealing with family relations and the knowledge mechanically will much more intelect and i will be able to replace/modify parts cheaply without stress of a shop doing his job right

lol @ you thinking that's going to sound good.

to each his own....for i want a real deep non ricey sound

ugh.

you obviously have a lot of reading/experimenting to do.

Quotes 1 and 2 are contradictory.

[uberSC2]

4in deisel style.. if you;re gonn do it... do it big

that's going to sound like butt, put a spiral flow on there and if you must then the flowmaster. personally I've only heard 1 flowmaster that sounded good and it was on a boosted s-series. I'd suggest borla, magnaflow, spintech (loud and dirty ftw), or even some of the stainless ones you can find cheap over that.

with that combo, i think the car will sound like its letting out the biggest fart, then as rpms increase, get a rasp to it.
