I was looking at PaceSetter’s MID-Tube ceramic coated shorty & mid headers..

I currently have an SLP Lound Mouf on my 1994 Z28 would I need a Y pipe or anything to install the headers and I've heard sotries of the exhaust sounding like crap when you add headers to them.. is this true?

 

I've heard form a lot of people that the Loudmouth sounds like *** with longtubes, but never heard anything about mids....
