Exhaust dp question


Recommended Posts

Some people say catless smells, some people need the cat to pass whatever inspection their state has, some people just prefer the way the exhaust sounds with it.

couple reasons to why people get catted

 

1) pass emissions. you will not pass emissions with a catless downpipe unless they are blind and cant smell

 

2) smell. catless smells bad and is bad for you. the extra gasses a cat normally removes or changes are now flowing freely and you can smell it

 

3) sound. catted will be a smoother sound and also wont 'pop' and 'crackle' as much

All of the above, plus there is tuning reasons to have SOME backpressure after the turbo, and the cat provides that, mostly in a free-er flowing exhaust as it seems you desire.

 

Also, it's better for the environment. Think about your kids, or future kids. :)

Regardless of if you have inspections or not, cat less is illegal.

 

It will be easier to sell your car with a catted DP. The future buyer may need to get it inspected.

 

Instates wher they just do a OBD2 scan to see if you monitors are ready, it wont matter, you will pass inspection.

 

And its easier to sell the car by going back to stock, and selling the DP separately.
