i have a high flow cat on bushcur exhaust and am thinking of going catless. Can i do this without getting a tune again? also i dont want a check engine light. I heard of o2 fixes but what do you guys recommend. Getting rid of a cat adds about 10whp proven on a lot of forums. Looking for a louder deeper exhaust note. WHat do u guys think

 

Sounds like a good idea You would probably see more gains if you got a tune again, but you should be fine without one. You can get a CEL fix off ebay for cheap and they DO work. I have one and have never had a problem.

 

how does it sound? is it loud ?

 

You will definitely notice a diffence. It made my Greddy exaust a lot louder, but I like it, because it was pretty quite before.

 

i am looking for a little louder. I heard you can def feel a differnce.

 

it will be louder
you don't need a tune but you won't see any significant gains
you'll need an o2 fix to get rid of a potential cel
