on all the downpipes i see i only see the lower O2 sensor

do they have the upper O2 sensor also?

 

its right next to turbocharger

 

aftermarket downpipes?

exhaust depot. for example.

 

The ALTA DP has 2 directly in the DP itself. They also included a Bung for a 3rd on the midsection pipe. In general, the 3rd is not used, we use the provided plug.

Here is a pic of my system, I was half way done with the polishing. One O2 sensor at top of DP, one at bottom. Dont buy any DP if it doesnt have 2

 

anyone have the exhaust depot down pipe? thats the one im interested in

my 3 inch cat back stops at where the 2nd cat use to be leaving the stock flex pipe,and exhaust depots include the 3 inch flex pipe which i need

 

I have all of Exhaust Depots line. Downpipe with resonator and O2 sensor. If you want a second (for tuning) just say so and he will put one in for you. 2.5" all the way back with dual 4" tips. You will have to verify with Hector that it will work with an aftermarket catback system.

As well I have his hard intercooler pipes with BOV. A quality product easy fitment and 1500 miles (so far) and not one cel.

 

1 before cat. & 1 aft. cat.
