So basically I got Dann to build me a Turbo back 3 Inch stainless exhaust only with Varex muffler and nothing in between. Dann got the Varex through his supplier and it was included in the price for the whole system.
Dann, heaps of thanks mate.
You put in long hours into this system and in the end it is a high quality hand built system and I am very happy with the finish product. Really this is a full custom work and I know other performance shops will easily charge double the price based on time spent fabricating it. I always wanted 3 inch and could not accept the 2.5 inch systems that are available off –the-shelve.
I’m also glad you like the ‘SE’..

haha It is not in standard form but they do have potential if done right.
Turbo Spool: Hitting full boost is more punchy like Dann would put it. I can feel the shove now when going WOT compared to before I could hear turbo spinning/spooling but the push is not as noticeable. From what I notice driving around the back streets to work this morning, the turbo is spooling earlier thanks to the 3 inch downpipe, it is a big difference and very noticeable even at low speed.
For performance I think any SE owner should look at aftermarket ECU before anything else because it really transforms the car. The first mod I did was the Adaptronic ECU + injectors and I had comments from another SE owner when he test drove my car on the track saying ‘this must be aftermarket turbo’ but I am on the OEM turbo… with Adaptronic the full boost comes in so much earlier compared to the OEM ECU. Don’t really have to be Adaptronic, can choose many other brands that are available on the market.
Varex: I played around a bit more with the Varex on my drive home. I tested with both open and shut positions and there was no drowning at all. When Varex was open I could hear the exhaust burbling behind you but not intrusive at all and I can hear everything in my car because my car has no sound deadening or carpet. Really more annoying noise is from the bad road surface on some part of the highway. Once I hit the smooth bitumen the open Varex is sweet, even at a constant speed, I had music turned off totally just listening to it. When driving with the Varex shut on the highway I have to say it is the same as factory.
Basically I now have most of the add-on mods except the Intercooler which is on the way. I have ordered an 'Ebay' cooler to cope with Summer heat coming very soon. I hope to install it and take it to Dyno to get it tuned for new exhaust and intercooler. Will post the results from before and after the installation of exhaust.
Some photos of the work.. Use the link to see more photos. Dann finished very late so I have not taken an installed pic in day time yet.
