ok so i drive a 99 civic ex d16y8 turbochaged witht he greddy kit.
my plans are 8 psi daily
i want and exhaust system that is relitevely quieet and doesnt take over my music, but also sumthin thats louder then stock with a nice deep tone.
heres my list so far ic ant narrow it down at all, from wat ive heard 2.5" mandrel bent str8 through design is the best for mysetup.

greddy sp2
apexi WS
apexi n1
tanbe racing medallion
skunk 2
feel free to add anymore, and why u choose watever exhaust u pick.

also im doing the AFC hack i got the V-AFC and bigger pump and 450dsm inectors. my question is i know i need a resister box and clips, but were can i find the clips? and also one of the caps is broken so i need to find another of those.

last but not least my autometer A/F guage seems to only go from lean to stoich and back, it does not hit rich at all..im talking both under boost and normal driving. people tell me it should be going lean to stoich to rich under normal driving but its not, anyone know why this is..it used to, but since the AFC install and pump install it doesnt????

thank in advance

 

i would go with a 3" thermal exhuast. thats what i got, i love it. if i were you spend $80 on rc 440 cc dont need a resister box.

 

i was told 3" is 2 big for me that i should stick with 2.5"
and the rc injectors are like 80 US each...a set of them go for like 250+US..

 

buy whatever exhaust YOU like .. ditch the autometer a/f gauge - its worthless. i'd say stick with a 2.5" exhaust unless you plan on upgrading in the near future. and just keep an eye on the classifieds, people sell injector clips all the time.

 

anybody using the tanabe racing medallion exhaust? if so how do u like it

 

think turbo mag did a comparison of all the systems last year, like 50 exhausts, I think greddy usually came out quieter and made decent power. maybe someone will remember the article and scan it for you.
