Gonna be doing some friendly runs with this guy I met on tiktok, he has a 6.1 Chrysler 300, he’s basically just a intake and catback. I have a 2000 ws6 it’s a4. Has a slp lid, magnaflow catback and cat delete. I’m adding Some long tubes next week with a tune will that be enough?? Or should I save some Dough for a ls6 intake and slp pulley first to add with the headers
