Hi im kinda new to exhaust systems. So I bought a BORLA PRO XS 2.5" daul in daul out. Lookin into the muffler I see that in the middle the ports/muffler connect like a XPIPE. I have a brand new XPIPE to install with my new Borla muffler. To get to the piont lol, I was wondering if it was piontless to put the xpipe in if the muffler works kinda like a XPIPE? Thanks yall
