2.5" makes more sense to me, I'm more for the low end for the power, unless I go to a bigger turbo, I don't need a 3". I still have CM springs, and haven't yet to put on. They are suppose to be the same spring rates as the stocks. Still need to figure out when I get those installed before AutoX on Feb 20.

 

thats expected on springs. i think even the pedders are a bit stiffer than stock, but not much. its only a problem on shitty roads tho.

also, wtf is up with the "silencer hose" thing. i should prolly ask ark but meh, im lazy.

 

incase the springs coil bind, you won't hear it. its the same thing with Teins.

Here is a link from Ark Performance. It explains a lot better about piping design. http://www.arkperformance.com/SearchResults.asp?Cat=13

 

Hmm... I was thinkin bout that 2, but I like the look of ArK Springs, An Pedders....well I jus didn't wanna pay for em after I ordered the Hahn Exhaust I'm thinking now that Ima jus wait a lil bit an jus stay stock height with em for a while

 

anybody try the treadstone exhaust?
