i have a 80 series on my bird how will a cherry bomb sound in the I pipe with the 80 flowmasters still there? bad good louder or just like plan old crap. im looking for louder. i tried getting my cat taken out but i dun want to set any codes off and i ordered a cutout thinking i could use it before the cat but no room anywhere to many bends so this is my last thing im going to try lol thanks.

 

Are you planning on replacing the cat with a glass pack or are you just putting the glasspack thier as a resonator, if its the latter it will get quieter, just like a regular resonator would. Sounds like something i would not do< but thats just me.
