I kept my cats for smog purposes but it turns out they provide just enough restriction to prevent that popping. I have 0 poppin unless I'm sitting at idle just revving the hell out of it. Small amount of drone but I've always been a fan. I'll post a fly-by soon my other vids at idle do no justiceLots of popping. Sounds good til bout 3-3500rpms. Then its just noise. Mines been like that for a yearand next week ill be adding dynomax welded or thrush welded.
OP have u deleted any of your 20 cats? Lol,6.
