Exhaust

A few days ago i picked the car up from it's winter storage. It was a fun drive home
I started working on the exhaust as i think it was to quiet. I started with building a dummy for the cat. I replaced my 3,5" magnaflow cat with a cleaned out 3,5" cat. Directly on the test drive the car hit overboost at 2,4bar. I think the cat was holding the turbo back, maybe a lot of backpressure? Well i think that will be sorted out when remapping later after i have changed the head and cams.
Picture of my fake cat with v-band flanges for easy swapp:


Then it was time to make some changes to the sound. I decided to remove the last of the two silencers that are still mounted on the car. I welded on a v-band flange so that i can change between loud and less loud. I will make some brackets for the exhaust pipe and weld on a nice end pipe. The rear end will also be fixed in a couple of weeks..
Without silencer:

In a couples of weeks i will start to mount the new head on the car. This head is rated to rev up to 8300 rpm. Lets just see when it stops making power. Hopfully it will produce som extra power

Started to work on the rear end

So, this weekend i started to assemble the rear end. Started with the wheel hubs and put in new bearings



New bearing pressed in to place, then wheel hub.



Then i started to mount my polyurethane bushings



And at last, started to test mount some pieces. I need to buy some more pieces to the rear subframe before i can proceed with the work.
