anyone have the stillen exhaust setup?? HOw it sounds etc.. Thanks

 

How do any of You guys Pass emissions Tests with either HFCs or Test Pipes?? Im still stuck between two also.

 

High-flow catalytic converters should not be a problem:
1. Plug into OBDII and get a read out. The technician will look for SES codes. No codes - no problem.
2. Sniffer test: many high-flow catalytic converters have passed California sniffer test, some of the most stringent tolerances in the U.S.
3. Visual inspection: some high-flow cats look similar to the OEM catalytic converters. The technician won’t know the difference.

 

We don't test here in Beaumont [yet] ,and if they do visuals I'd stay away from cats. like random technology, stick with OEM looking cats.

 

In OR it's every two years you have to test, and it's a pretty easy swap to put the cats back on for the test. Don't know that the test pipes would pass, but wouldn't even bother finding out.

 

exhaust question...will changing the y pipe and or down pipes make the rest of the stock exhaust sound louder??? Lookin for more sound with some power!
