I am seriously thinking about getting an ebay tbe this month but i dont have the money for a tune also.Would installing without the tune be bad considering it is my daily driver, and will it hurt my gas mileage.

 

an Exhaust without a Tune is alright ..

 

You will be fine.

 

do it...

 

I just put on a cat back over the weekend and it shifted me a little lean around 5000, but on a stock tune you are rich in that area anyway so you'll be fine.

 

you might actually get better gas miliage even without a tune. that stock exhaust is pretty bad. If your going catless make sure to get some O2 sims. Then when you get some more loot, tune it. If you don't have an intake yet that will increase your gas milage also.

 

Dont get simulators. Get the o2 foulers.. there like $5 total, just drill one out 1/2".

 

how do i do the fouler

PM me if you want to buy a defouler from me, I'll drill it out for you.

 

i ran my TBE without a tune for a while. was hesitant about tuning and voiding my warranty entirely, but now i am glad i did it.

the exhaust by itself was a nice, but subtle difference. faster spool, and a little more oomph for the butt dyno.

after i got it tuned though, holy hell! so if you're gonna get the exhaust without the tune, i say go for it. just get it tuned first chance you get, it makes a world of difference power wise.

 

evos are so ungodly rich from the factory you can put an exhaust on with no issues whatsoever........except noticing more black smoke at wot

 

Get the defoulers.They work great!

 

Where can you get them?
