Quoting Steve001:
when I went down to the muffler shop the guy kept talking about glass packs. Was throwing me off..
He was most likely talking about using glasspacks inline as resonators. I've done that on an H2B civic I had with a full 3" exhaust, and on an NA car the noise is REDICULOUS (as Im sure you know).
I had the Kiddracing tri-y header with 2.75" collector, catless, into a 3" after that. I had 18" and 24" glasspacks in the Bpipe and a 3" vibrant stealth single tip muffler. It was fantastically quiet, I loved it. From inside the car all i could hear was intake noises with a hint of exhaust note, from the outside is was basically the same, but slightly louder exhaust wise. I went from being able to be heard going to a friends house from a couple blocks away to being able to pull up in front of his house without him knowing I was there, FWIW. Best part is, it was CHEAP. The 24" glasspack only cost me $24, the 18" was $20. Hard to argue with that, eh?
G/L Steve, hop that helps!
