I was wondering if the cats will make my car alot louder? Anyone have them with headers? is it loud , and video or sound clips?

 

I have them without headers. They did make my exhaust note louder. Hard for me to say how much louder over a stock setup since I put them on after I already had a coupe middy and HKS rear section on.

I am very happy with them....sounds amazing at WOT.

 

did the hks muffler help you more over your cats???

 

If I am understanding you correctly, you are asking me if the HKS or the Crawfords gave me more gains?

Definately the Crawfords gave me a bigger performance gain over the HKS. Escpecially at the top end but an overall improvement was felt.

I've been itching to get my car to the track one day and see what it does in the 1/4 mile. One day.

 

Do the Cats smell in the morning ? is ur check engine light on?

 

No to both questions
I have never heard or "smelly cats" before.

 

O Dude You Have Front And Rear Rims

 

Is it worth buying used cats?
