Ok, so i exchanged my magnaflow cb for a 3 inch vibrant cat back from modern performance. The damn resonator in the magnaflow went bad for the third time and I decided to try something different. I didnt realize it was a 3 inch(stupid me) till it arrived today. As you can see, my mods dont exactly warrant a 3 inch exhaust. I want to know if a 3 inch will actually be detrimental to the car or does it really not matter? I do like the loud aggressive sound of the vibrant.

 

you will be fine. its not that big of a deal. if you like it then keep it. i love my full vibrant set up

 

Thanks I didnt think so but wanted to make sure

 

no prob

 

You'll just have to get the Vibrant header/dp now.

 

Thats def in the near future!

 

i love my full vibrant setup, but it is extremely loud even with a cat.
