H pipe w/ 2.25" piping and it sounds real nice in my opinion. I'm very pleased with them.. they sound loud... not too loud thoough.. deep.. nice idle.. good at high rpms.. he told me they would last and sound good until they rust out. i underestimated glasspacks.. no wonder why they've been around for so long.

I just had a couple of questions about glasspacks because i was thinking of buying some. How long have you had them because i want to know if they stay loud and deep for a while and dont lose their sound? and, would you recommend them?
