7gen i4 GReddy SP2 -- Heads Up - Page 2

so what makes the greddy or apexi better than just a regular fart cannon if theyre basically just straight through too?

Sound mostly i guess... it doesn't sound like a fart.

Also, the weld spots are done better, and look of a higher quality.
And GReddy/Apexi are respected brand names.

The mid-pipes are 60mm which is a good size for our engines.  The resonator and muffler are tuned to the engine.  As mentioned, the sound they put out is nice and throaty rather than weed-whacker-ish.  Please look at the videos that Spaz posted and compare those sounds to some of the cheep stuff that you hear on the street (usually on Civics and Corollas). 

hahaa.. yeah i saw this civic the other day with this really wet fart sounding exhaust.. looked like a torpedo..

i played like my car didn't have any get-up and let him pass me with his squat-mobile... when he got ahead by about 3 car lengths, i floored it past him..

he came up next to me at th enext light and asked what i did to make it sound so good, and i said "well, i have quality parts.. that makes a difference.. and i have an intake, which is probably what you actually heard".. and he goes.. "hmm... so that's what good shit sounds like huh?"

at which time the light turned green, and i left him sitting there.

haha sweet. id love to do that, i cant wait to rebuild my mtr and get a sp2.

quality parts, someone told me to just get a cheap bombz intake off ebay, thats not quality though. do u suggest that i get a better one like AEM?

Ah you're mixing the two...

GReddy/Apexi are the manufacturers of the SP2/WS2 cat-backs, respectively.

The intake can be the cheap bombz intake, coupled with a K&N or AEM filter.

Now I have an 03 (7th gen) so this isn't compatible for you (idt), but for comparisson, i got this one in red.

so the intake dosent matter so much its self but gotta have a quality filter. question on the exhaust what is the purpose of the resonator?

The resonator, along with the muffler and mid-pipe size, tune the resonant frequencies of the exhaust to the engine.  This helps to produce a pleasing sound rather than a cheap fart-can buzz or a the bubble heard on rev-down from a mellon-launcher.

In racing applications, the resonant frequency can help make a bit more power by creating pressure fluctuations that are time-matched with exhaust valve operation.
