Time to fit my beer bought 3" exhaust.
The car is up on stands, and as I'll be working underneath it.....
To get the old exhaust out is a fairly simple job.
Just drop one axle...
...and wiggle it out.
Here it is next to the new one
The old 2.5" pressbent has always produced good power.
I put it down to being fairly straight, with only mild bends
Whereas the 3" has 2 big 90 degree bends at the back, and the bends themselves on the way through, are more severe as it has to twist it's bulk more to clear stuff.
To get the new one in I had to remove some stuff.
And there is no way that this....
....will fit through here
...will have to come out also.
Which is a bit of a problem here..
Because that is where my Doctor said I have a hernia.
Probably got it from a heavy bout of laughter whilst removing an R200 diff.
Thank god for the humble jack.
Plenty of room now
To the other end.
Here is the dump.
The original -R engine came in a front cut.
And when they say cut, they mean everything, including the exhaust.
Here is where the engine fitter has adapted the 3" dump to the cars original exhaust
And here's where my new piece fits in. Just hack off the original 2.25" bit and on she goes.
The dump isn't much better but until something better comes along....
....we're stuck with it because of the rear housing of the turbo.
If you look at the bottom of this pic, you'll see the wastegate arm is built into the turbo outlet.
So until we get a large injection of funds, this is it.
Took me a while to finesse.....
....the exhaust on.
(The one on the left caused some blood and exclamations of "oh bother" and "oh dear, I appear to have struck my thumb")
My adaptor needed to have an S bend, so it didn't work quite as well as I hoped and now I have an exhaust leak.
I'll have to take it to a professional to get it fixed.
The new exhaust is both quieter and louder than the old one.
Quieter low down and louder up high, with a much more pronounced howl which is a trademark of these engines.The last time I was listening to the engine howl I ended up with a speeding ticket.
I was much more circumspect this time, besides, it's raining and the car just wheelspins when it hits boost in 1st, 2nd and 3rd.
The turbo is whistling more now, and the engine seems to be revving out better.
Feels more powerful from the pants dyno, but I'll wait for the real dyno to give a verdict.
