im thinking about cutting off my cat and running open dp...just a stock dp. should i do it? i want to get insane turbo noise....lol. im ready to put my ty away around next week or so. so im thinking about doing it. is it worth it?????

Guys on here say its night and day difference with how fast it spools running no cat. I would not do it unless I had enough supporting mods to run 17psi. Like 3 bar, walbro, and AFPR. If you have all that. Then its woth it. Some trucks get boost spikes more than others, I would just want to be prepared to handle a 2psi boost spike if I was not running a cat. You dont want KaBoom!

but doesnt cutting your cat out cause overboosting

yes it does on most of the trucks, but with a different chip, and a 3 bar map sensor, your ECM still has control after 15PSI over how much fuel it needs to give
