SW chip and smog check question
 

I have a SW chip for headers/sport muffler. Left it in for smog check with stock exhaust.

Passed the smog... but will there be problems leaving the chip in with a stock exhaust? I don't want to change back to the headers/sport muffler yet.

It seems to still have better throttle response when compared to the stock chip with stock exhaust.

Thanks.

Why not go right to the source? Steve would be happy to answer your questions.

I have his chip in my 89 911 Cab and it passed smog with no problem.
