so i have a 93 ex and i bought a greddy kit for it. the thing is my exhaust was just a shitty straight pipe welded to my header.(came w/ the car) so i bought a 2.5" dp and high flow cat and 3" exhaust from kteller. but i've heard that the blue box will create detonation over 5.5 psi? is that true?of not what psi?.soo if i throw this exhaust on, will it it bring up the psi too high? or will i be safe? and if it will make it to high can i just make a mbc and bring it down?
