After buying the D3 headers & cats last spring, I finally got them installed... Initially I thought I'd take them to a shop to get installed, but I decided to tackle them myself.

It was a huge pain! :)

I got one side in over a weekend, and it took a couple of trips to the store to get the right tools. But the other side went on in about 3 hours without a problem.

I ended up doing it on a set of four jackstands and without having to lower the engine cradle. (the service manual states you can only do this by lowering the entire engine - which is why I thought I wanted to take it in to get done)

The exhaust note has changed a bit, but not a huge amount... I have a rough tune that was done for my by Wait4me but it'll be going in to Hennessey for dyno-tune when I get a chance in the next few weeks. I'll post the final dyno numbers with all my mods then.

Well let me be the first to commend oyu on your bravery!!! I haven't worked n a car under just jack stands since I was too young to consider the consequences if the call fell off..

Also, I would strongly suggest that you keep that stock exhaust since it may not be available in a couple of years.

I hope you obtain the performance improvements you are looking for.

Please let us know how it comes out.
