My banks elbow and pipes work great. Due to debate on here about the bigger pipes I recorded parameters on test runs before and after. There was no change in boost or spool, I even seem to feel the spool was slightly faster but not measurable. No way spending more money to replace banks elbow and pipes is worth the dough. Take your wife to a weekend getaway instead, much bigger dividends
I'm also a facts based guy, so if you truely break it down to physics, the larger volume will be slower to compress but will be cooler air - so just about a wash in power I'm guessing. I argue the stock turbo has no issue building pressure in the larger banks IC and pipes, so I enjoy the advantage of cooler air. My banks IC kit did drop the EGTs 50-100 across the board.
