Is there any manufactured FULL, from intercooler to throttle body, aftermarket replacements out there? Would a "better" flowing tube from intercooler to tb make a difference, or is that plastic tube ok to keep and just get rid of the intake tube and noise maker?
On that note, does the noise maker rob any power in the first place?

the stock rubber hoses always fit the best so no need to replace. But we offer just the pipes to replace the resonator on the hot side, and then the noise maker delete on the cold side. These are easier to install than the entire hose kits, and much more cost effective. We find replacing these two parts to mainly help with throttle response as the noise maker actually bleeds boost to activate it. Use the money you save for other mods.
