91smokedgt

Im not sure if this is normal. I have a 99gt 5 sp with LT o/r x and 2 chamber flows. it sound great. my buddy had a 01 gt auto with stock manifolds and o/r x with 2 chambers flows not sure if they were 40's or 44's. His seemed a lot louder than mine. why is this??? is it the trans being different?

He could have a different type of x pipe. Some are designed a little differently.
