Ill be getting a boost controller pretty soon then I ll be saving for a tbe and a pro tune. If I go ahead and buy a downpipe would it be ok to run open downpipe or midpipe (everything up to the rear o2 sensor) and go ahead and get tuned? Would it hurt anything tune wise to run it this way until I get a catback or would I have to retune for the cat back?

 

I would wait till you have all the bolt on's you plan on installing then get the tune.

 

dang!! ok thanks

 

agreed!

 

I agree with the others.

Wait until you get your parts installed then get a tune.

That will save you money in the long run.

 

check out invidia cat back. inexpensive and good quality.
