Currently I have z1 test pipes, z-tube, and a pop charger. Which would add the most power, x02 exhaust, Kinetix Racing V+ Plenum, or a motordyne 5/16" spacer??? Thanks

 

i say the spacer with a tune

 

best bang for your buck hands down 5/16 MD spacer. Do you have a revup? If so, you gotta add the mrev2. the spacer will add a legit 10whp for $200. cant really beat that.

 

I have an 04 5at so its not a rev-up. And how hard is the install? Does anyone know of any shops around KC??

 

And where would I take my car to get a tune?

 

basically i googled and found this

i'm not sure if it helps you but its basically a car forum for KC.

 

and is this the xo2 exhaust?? http://cgi.ebay.com/ebaymotors/02-03...item255772a753

 

It comes with detailed instructions that makes the install pretty easy.

im wondering the same

 

basically its a knock off of the XO2 which really doesn't put much faith in the quality. I was thinking about this myself but its not really worth it. There were issues like the fitment was off so it'll touch your bumper and melt it. They claim T304 stainless steel but it isnt. The quality is much worse and will rust. The tips are terrible. This is just based on owner accounts I read. On the other hand some people say its fine. Its really up to you. I would pass though. Search XO2 exhaust and see for yourself.

 

So it isnt the x02? where could I find one or another exhaust in that price range? and would headers do anything for me?

 

headers for our cars are a pain in the *** to install. gotta lift the engine out to get enough room. not worth the trouble.

If you really want it....this is the XO2.

I would save up though....

 

I just want more power and a different sound. would a spacer make a different sound along with a plenum? Im just sayin cuz my friends say my car runs like a gerbil and sounds like a hampster.

 

also, what would a y-pipe do? Sorry, I just havent gotten around to modding much and am trying to learn all of this stuff because in spring KCSR is starting up again and I wanna come out with some new stuff.

 

wow you should really search..you cant use a plenum with a spacer...the spacer will make a different engine tone..much deeper..especially if added with a intake
