Trev FF yea, the stock zx3 header detunes it soo much. the svt header is where its at. from 99 whp stock to 130 whp thats pritty good.

ZXthrizzle05 with the same mods when I was NA I made roughly 131whp on my zx3

It is 2.25" exhaust all the way to the end right?

Trev FF i bought a svt header, cat, an high flow flex. $90. doin the egr mod to it. i have an AEM short ram intake. i did a resonator and muffler delete an put a fireball muffler on it. so when im done, ill have svt header, cat, flex, straight pipe to muffler. and an AEM short intake. how much HP does this add?

razorrik actually the throttle body doesnt give you any performance gains,just better throttle responce,but if your gonna go nos,sc or turboed it will help.other then that you wont gain enough to even show on a dyno.and most kits like powerworks comes with a upgrade throttle body anyways.and you will gain something on a full exhaust(header back) but a cat alone wont produce much.youll get more out of a good tune and a cai,,but start somewhere and follow thru,,full exhaust or full intake,,dont just add a part to this and add a part to that,, sit down look at what direction your really going for.street performance,track,daily spirited,drag. research then buy.ive seen a lot of guys just start buying and had bought a lot of stuff they didnt need or couldnt use in the direction they were going.and theres a lot of guys on here can take you in the direction you want with a lot of great info from na to fi .

trevor well if i did the factory intake (SVT) box then the cat back should be good rite? whould it be best just to add a cat back to the stock zx3 header and cat and flex?

Food for thought?

What if you factor in adding a full factory SVT intake/airbox?
01-02-2008 08:53 PM
dirtbrown id say just get an intake and throttle body....and thats gonna be about the same cost

id say with a stock intake....the exhaust will only give u 5whp max...thats alot of money for nothin....maybe a tune and intake?
01-02-2008 08:50 PM
trevor i have not put an intake in yet, though i did make a sort of ram air type of thing that feeds air from the grill directally into the snorkle. i think i will just put a svt snorcal on it. is it really a waszte of money????
