Holy crap it seriously feels like I lost a good 20 horses. Feels like the car can't pick up anymore.

Now I can hear my ztube/pop charger.. It sounds really nice and unique.

 

xo2 is a grunt of an exhaust all right. you might just need to give your car some time to get used to the stock exhaust again. i went...

stock
injen ses
injen ses & test pipes
stock & test pipes
xo2 & test pipes

as annoying as the xo2 is with the windows up, i love how mean it sounds at high rpms. oh and its loud as fck under bridges.

 

^ doubt its as loud as mine :-/

 

Yea I actually just realized something with exhausts for this car.

You may not feel gains at first when you add a mod w/out a tune.. but after a while w/ that mod your ECU gets used to it.. My ECU was used to test pipes and free flowing exhaust... and now its cramped up w/ stock... I'll give it a week before my power is back.

 

So why'd you switch back? Did I miss something? I did notice you like to try a bunch of different things though

 

Did you put the stock cat back on too?

 

no i still have test pipes.. stock exhaust note is now even quieter than stock itself.

 

I just like the stock sound... plus i had complaining neighbors with my exhaust.

I have my eye out for a fast intentions exhaust.

 

You should keep an eye out for the Motordyne exhaust as well.

 

^^^ yes is this any closer to a public release? Teaser pics maybe? I'll be saving for a new system this winter and right now its between F.I. and this one to be seen.

 

when i went back to stock i actually felt a big difference in the low end, but i suffered in the higher rpms. i like my car with the stock exhaust, the better low end response is great for the city. stillen sc helps a lot too!

 

Hello fellas,

Well, I'm wanting to chance my stock exhaust. yes I to want a fast intention exhaust. Any suggestion? should I leave my stock on or go with xo2 to any other dual cat? your thoughst will be greatly appreciated.

Remember I'm looking for more high and low end exhaust!!!! to compliment my AEM intake.

thanks

 

don't get x02.. get the FI unless you can't afford it.. you could get a used hks for a pretty good price
