I've been driving around with this for the past couple weeks, testing it out. I can say nothing but good things about this! The engine just feel like there is more grunt and it comes on faster from a dead stop. I'm really starting to notice some wheel slippage now!

Do not buy this if you want good gas mileage, I lost about 3-4 L/100km (around 5 MPG I think). It's pretty much impossible do better than 14 L/100km (almost 17 MPG) driving around the city.

 

nice, all you need now is to complete your setup. lol

i too am shooting for a complete TBE from CPE.

 

I was looking into picking some CP-e stuff, they are located about 40 mins from my place ..so I can drive on up there and check out their shop

are you sure the gas milage change isn't just from you Stomping on it more now

 

Exactly, you sure you are not driving the car harder now?

 

Is there a noticeable difference in turbo spool time? I am really thinking of getting a test pipe of some sort. How do you find the exhaust sound in comparison?

 

I got an MXP testpipe - resonated on my Ralliart and if there is a difference its very minor. Just slightly deeper (on stock exhaust). My sister says its quieter.

 

Did you notice a change in gas milage?

I know my scuby friends are getting good HP #s with similar parts but no ill effect on gas.

 

I gotta work out the CEL before I determine fuel efficiency. I heard with a CEL the car runs richer as a precaution

 

UPDATE

Well my gas mileage is getting better now. My check engine light came on for 1 day, and then turned off on its own. So far, still lovin' it!
