Does it smell? |
The smell varies. Sometimes at the red light if there is no wind blowing or there is wind blowing in the other direction. |

Sec 2 delete.
How is the smell if any with your set up Biginboca?

The smell is strong when you smell it, but you will smell it pretty much only in 2 circumstances.
Coming to a red light with your window a down. (After you have stopped for a few seconds the exhaust wave catches up to the car and you smell it inside the car for about 10 seconds before it seems to mostly dissipate.)
If you have the car running and go to put something in the trunk. |
how do you guys pass inspection with the headers for no cats at all? I'm just worried about that. If that's the case I might need to keep stock ones to swap out when inspection comes. I was also looking at the Supersprint HFCs but that might have to wait till I do my suspension work first and I haven't had much luck finding anyone's experience with those
would a muffler shop be able to fabricate high flow cats so I can have the best of both worlds? I'm also afraid my car will be overly loud with my current set up
