I'm going to install Stillen X(H) pipe, and I also had to check on
my half shaft bolts. I have Borla cat replacement pipes. Now
I'm wondering if I need to wait on the Borla pipes until I check on
the loudness of the X pipes. I know a lot has been posted on X pipes
and loudness - I just thought someone might have knowlege on these 2
brands together - or a thought on the sound insulation of the Borla cat replacement
compared to the stock cats.
