I have new edlebroch headers with a straight pipe in place of my stock Catalytic Converter. going into random tech cat back exhaust. well its raspy after break in time of 1 year and its getting to me. i was told that if i put back a glass pack or cat it will solve the problem (in place of current straight pipe). so im asking you the readers, use a Glasspack or Catalytic Converter FTW. thank you in advance.

 

I have a Dynomax bullet muffler in place of my cat with Mac mids and Magnaflow catback. I think it sounds beautiful, I should say mean and powerful, with very little, if any, rasp. However I dont know how it compares to a cat since I havent run one with the header and catback setup.

 

Why not do the environment a favor and put a high flow CAT back in.
