Hmm, ill give Phillip a call then. How much of a difference we talking? A lot or just noticeable? And yea, the china turbo sounds good but i would rather not replace the turbo every time i change oil. :rofl:
Do you have trents 4" intake to or...
You will notice a HUGE difference in whistle going from the stock airbox/tube to a open air metal intake.
Yes 5"is overkill anyway my 4"intake sounds sweet
