2.5" minimum. Just to give you an idea. A customer of mine went from a 2.5" exhaust to a 3.0" exhaust. Below are the results. He's not going to have me retune it until he does the 3.0" downpipe, ramhorn exhaust manifold (currently has a log manifold) and ITR cams (currently has GSR cams)

Re: 2.38" vs 2.5" exhaust for turbo setup
right now i have kamikaze headers to be installed with a 2.5" collector.
im debating whether to put a kteller 2.5" exhaust piping with a DC sports 2.5" muffler or putting the full buddy club pro spec exhaust which is 2.38"
my future plans are turboing my d16 with a gt28r turbo. my goals are 300+hp
do you guys think it will be better to go with the 2.5" exhaust or 2.38"?? i also plan on using a test pipe and i dont believe they come in 60mm.
thanks guys

Re: 2.38" vs 2.5" exhaust for turbo setup
basically it boils down to a few things. the size isn't much in difference as someone mentioned, but these are measured in OD (outside diameter). So even the buddy club at 2.36 is OD, so your looking at closer to 2.25" ID. KTeller can offer a 2.5" OD to give you a slight edge and benefit and I would look at the bolt up kit, where its easier to install and just pop on and go.. email me and i can save you a good bit off our list price if your able to purchase mild steel. stainless wouldn't qualify for the discount.

I highly doubt you would see a difference on the dyno between 2.38" and 2.5". Not a lot of difference there. If your current setup is quite and you like it, I would keep it. You can always run a cutout for big power.
