Gen3 VQ35DE FBO with Holley EFI, equipped with stock cams. For those interested, it was dyno-tested on a Dynapack. I learned this the hard way, but at least I’m set up for cams when I’m ready. I’ll probably gut a manifold and retune later on.
303 WHP and 238 TQ on a 3rd gen revving to 7500 RPM with stock internals. The Holley robbed some power, but that’s fine. I’ll be working on gutting an OEM manifold this year and re-tuning. I spent good money on an equal length y-pipe, but it still sounds unequal length.

It’s not making 300 until over 7000 RPM, and the rest is significantly underpowered. You’ll achieve the same top end with more mid-range using the stock manifold. These Hiram setups need upgraded cams to really shine. I made 360 HP and 307 lb-ft with full bolt-ons, cams, E85, and the Hiram manifold.

I had a new y-pipe custom-made to be equal length. Unfortunately, it cost $1700 CAD to get it done. Exhaust work is not cheap nowadays.
