I just dropped off the MU (3.1) at the exhaust place up the road.
He's charging me $450aus for 2.5" mandrel bent from the turbo and running along drivers side, instead of crossing to passenger side.
Free flow muffler and hotdog near the end are included.
Is $450 a reasonable price?
cheers

Pretty good Rodger, I paid $720 for a 3 inch.
Cheers Bruce.

I got the car back and it gets full boost earlier and more easily revs quickly to redline.
Now for my gripes...
No flex was put in. How important is it and how many of you have had trouble without one? He wants $100 for it.
No heat shields anywhere and the pipe runs close to gearbox, torsion bar and rear shocker. Should I at least put one in near torsion bar?
cheers.

dont think any of these will be an issue but check them after a good run just for piece of mind. I would be more worryed about fuel and brake lines getting hot.
Flexi pipes are expensive There job is to allow the pipe to expand when hot. Old cars never had them and never cracked pipes so maybe they are a con I dont know for sure.

One of the bolts rattled loose cos didn't have locknut and was making a racket. Also noticed no hotdog, sounds good anyway.
The bloke wasn't happy with the amount of vibration at the tailpipe so installed a flexi for $100 and it made a difference.
Also, got him to redirect the end tip downwards so my bumper doesn't go black.
Can fitting a flexi and the tip mod cause a loss of boost? I'm a half pound lower now at 11psi after I picked it up, whereas this morning was 11.5psi. The temp did climb to 32 degrees in the arvo, would that contribute to less boost?
cheers.

I wouldnt worry about half a pound. Air temp and oil temp can have that much difference.
Only things that could of affected the boost on the exhaust would be a shocking weld at the flex pipe or very tight bend at the end.
Its more likly you didnt test it the same way

Any chance you can put up some photos of how he fitted the exhaust to the back of the turbo? I here it is a tight fit. I guess a body lift would give you a bit more room when making one?

Looks like a tight fit. I was looking at fitting a 2.5" dump pipe then join into 3" after the fire wall. Will be doing a body lift first before the exhaust.

He didn't bolt it to the turbo. The new exhaust starts from about 1 foot from the turbo.
The new flexi is about 1-2 cm from torsion bar, can the heat affect the bar in some way?
Geeves, it was tested the same day. In Melbourne, you can get 15 degrees in the morning and 35 degrees in the afternoon, which is practically what happened on that day. The next morning was normal boost so I think the high temp/low air density in the arvo had a part to play.
