I will be getting a 2.5" cat but which length should I get for my 4-2-1 headers 12", 14", 16", etc....

 

Any ideas

 

When I ordered mine..i just told them 2.5 in/out..and they sent me a universal Car Sound 2.5 in/out high flow CAt.

 

Or you can just reuse your stock CAT and save money (that's what I did). In reality, high flow CAT won't give your I4 engine car too much HP gain...
I'm gonna sell my Carsound CAT at Ebay wink.gif

 

Hey Silver_Tibby how much you want for the carsound cat! smile.gif

 

If I sell, I will sell it between 59 and 69. Then again, there are Carsound Cat in Ebay going around for 69. You might wanna bid on it.

 

I'll buy it from you, just let me know the price and shipping. My zip is 06106. I'd rather buy it from someone here on TSR or a buisness rather then on Ebay, I love Ebay but when it comes to car stuff I just don't trust those people too much.
