You would be much happier buying an Rtek7 2.1 and a Racing beat downpipe, then weld the fitting in about a foot down from the stock O2 sensor in the same orientation as the stock one, as in have it sticking down into the exhaust from the top so that water can't collect on the sensor. I welded mine in a bit closer but ended up moving it downstream a bit to prolong the life of the sensor. Any muffler shop will weld in the fitting for a few bucks, just have to drill the hole and weld in it there.

 

Awesome, that sounds great!

Also, you said get the RB down pipe. If I get the downpipe, can I k eep my current exhaust and that will 'restrict' me enough so my turbo stops freaking out so much?

I'm a big exhaust nub...and...everything else nub. I'm learning at least, eh?
