Ok, I trust all of your opinions, so i'm coming to you for help. I am currently trying to build an all motor/100shot of nitrous on my Teg LS. The question i have for you guys, is what size piping to run. Currently, I'm running the LS AEM CAI, and a 5 zigen catback exhaust. I was wondering if i should get just the reg. LS DC sports 4-1 exhaust, or step it up to the JDM 4-1 w/ the 2.5" collector. This would mean I would have to get a 2.5" inch exhaust, which would be more money. Also, I was wondering if i should enlarge my intake piping as well. Or for money issues, just get hte regular LS 4-1 header. So, i guess my basic question is, will the upgrade from 2.25" inch to 2.5" all the way back be such a big difference that i should suck it up, and pay the damn money. Because keep in mind, i will be spraying a 100shot. Also, i will be running a race port and polished head.
Thnx alot guys!
