searched, and couldnt find anything. i know its out there, but i dont think i used the right combo of words. but anyways, is a 60 mm piping diameter with straight through muffler too restrictive for 6-8 psi on a d16y8? i plan on buying the greddy 18g turbo kit. link me if you have the correct places, or post your thoughts please

It wouldnt be my first choice depending on your priorities. If you dont mind a large exhaust and you wont run into any spiking issues you definitely should upgrade.

I love my Apex'i RS, 60mm with chambered muffler, and didnt bother to switch it out. Running 2.5"dp to 2.5"TP to the RS, and I made 248/174 @ 7PSI. Probably could have made more with a different exhaust setup, but judging by those #'s I'm not too far off of similar setups with larger exhausts. Except for those freak motors making 270+ @7PSI!

well i really want the rsr exmag right now, but im just wondering if itll be enough of a bottleneck when i put on the turbo to matter.

Will it make a difference? Yes.

Will it be a huge bottleneck and not allow you to make decent power? Nope.

I made 323 whp at 10 psi going through 2.25" exhaust with no cat and 3" dp. B series LSvtec though.

I think it will be fine, just not optimal.
