Well car is a 99 m6 camaro stoke bottom stoke heads ms4 cam planing on shooting 200 shot of nitrous I am currently having LT 1 3/4 hooker headers . Do I realy need to upgread the headers to a 1 7/8 for this big shot to reduce back pressure to tge engine . Or has any one tried shooting this much
with such a 1 3/4 . Car also has a matching y pipe and a borla cat back . I am runing the car N/a and car pulls crazy 400 whp with flame from the exhaust on 5th gear

 

You don't "need" to go bigger, but sure it will help some

 

Save ur money not worth it. If you had big cubes and was running a bigger shot ya. If you want more air do true duals w bullets. Im but it will be loud so if its a street car leave it. I would invest in weight reduction or heads.
