Reply to "Photo Blog: LS9 Engine Swap (6.2 liter OHV Chevy V8, supercharged, 638+ BHP)"

After almost four months straight working every weekend, we finally got a weekend off to work on our own car!

Since we installed the LS9, we have been using the exhaust system that we made when we installed the LS3, including the extremely restrictive LS3 exhaust manifolds.

We started the planning stages of our new exhaust system this past week and are finally getting started on building it.

The LS9 came with what is best described as a shorty header. It is constructed of stainless steel and it flows extremely well for a stock exhaust manifold. We thought about making custom headers but we decided we wanted to keep the engine as stock as possible.

In order to get our exhaust system perfect, we decided to buy some PVC pipe to mock up how we want it to flow. After we got the basic design, we started building it.

We're going to keep some of the details hidden until we get further along but here are some pics of our progress.













We will be bringing the exhaust up on both sides of the engine and out the back.

Not bad for a couple amateurs, right? Wink
