Hey Guys, Up for Smog like many of the people I noticed on the board.

Silly Question, but I am Stage 2 Pro Tuned by GST..But can I slap on my Downpipe and pass? OR do I need to Reflash back to stock, then stock downpipe, and stock up-pipe?

I also have a UEL Header installed also..back to stock?

Thanks

 

visual is what will get you depending on how "cool" the shop is. The downpipe will get you through the sniffer portion. Shouldn't need to reflash, just drive conservative over there to stay out of boost. Just make sure to get the pre test. The header is an easy swap and can be done in a few minutes. Good luck!

 

Yup I had to go through this recently. All I did was swap my downpipe to stock, and passed the sniffer no problem. Like derek says just find a shop that will overlook the visuals. They didn't say sh** about my cai, headers, uppipe, etc. Good luck!

 

if u have a stock tmic you should pass fine

 

Stock down pipe and maybe install the stock intercooler for visual and you will be fine even with the tune.
