Deleting cats and subs questions
 

Got two questions on deleting my cats and my new subs, well first off I'm planning on getting my cats deleted tomorrow and would like to know what to except with sound and performance( I have a greedy se and a injen short ram) with the subs I have two twelve cvr kickers with an adiopipe 1500 watt amp and would like to know any tips on getting a better sounds and getting rid of rattling around my trunk. Anything will help, thanks :)

Well all my cars are catless it will sound better for sure power gains im not really sure about. Expect a cell light for the #2 O2 sensor. I have a spacer in mine, you can also do an electric fix if you do a search you should find it.

dynamat it {thumbup}, wont eliminate rattling though

make sure you use some non foulers or like item to space out the sensor so you dont get cel.

How do you pass emission with no cats ?? You won't get any power gains from deleting your cat or gutting it its' been dyno proven on a lot of cars the only way you would get power from it if it was clogged to begin with.
