so, i bought my 04 coupe 2 months ago, did some searching, ended up with MD 5/16th spacer, JWT pop charger, z tube, HKS true dual, and just did the ART pipes. they are brand new v2.2 .... other than having to trim a heat shild stud on drivers side a tiny bit, they fit perfect. i dyno'd before and after the pipes, on a dynojet 248c , it did 248.61hp/241.37tq before the ART's and 263.63hp/249.14tq after the pipes. i have yet to hear any rasp, and the thing purr's at mid rpm. needless to say i am very happy with this mod!

 

Good numbers

 

Good to hear and nice performance gains!

 

thanks guys. other than that, it seems the pop charger z-tube mod was the best feeling mod. i didnt notice much if anything from spacer and exhaust.

 

Id like to do the same mods but a different exhaust.. good numbers!!

 

yes i agree. i sold my pop charger but i want a new one now. you can really feel it kick in at around 4k. and it just sounds mean.

 

lol I misread the title of the thread at first and came in here to put you on blast for saying the ART pipes were "rice". Glad I didn't have to and congrats on your mods, nice numbers as said previously.

 

Haha I have a big horse power diesel. I will call a ricer as I see it. Hahahahaha

 

i will say to anyone looking at these pipes, they do sit a tad bit lower than the cats, so beware.

 

Are they noticeably louder?

 

full throttle, hell yes

 

ummmmmm, yes.

 

I want the art pipes so bad!

 

look what santa brought me today!!!

too bad its winter or else these would be on in a heartbeat

 

Damn!! Santa was good to u!!
