Hey ya'll, Quick question about cats! First off, I got stock cats with dual flowmasters. Well, I need to change out my cats and was thinking about putting on some SLP high flow cats or the Pypes high flow cats from AM. I couldn't find any sound clips on youtube just for out just out of curiosity sake... will it sound any different if I do the switcharoo? If so, What brand out of the two are better? Thanks in advance!!
