3" Exhaust - Dump Pipe and Cat only

[apalsson]

OK, we are back on the prowl and feeling like a million bucks!
Looks like the ticker is in a fine form and I have been allowed to drive again!!

I got my mechanic to fit all the gizmos (3" Redback dump pipe with Hi-Flow Cat plus the gauges)
A neat and clean job at a reasonable price.

Anyhow, the outcome is the car feels a lot "lighter" to drive. More responsive generally feels better. This is strictly anecdotal at this stage because I haven't done any checks on torque yet.
EGT sits on 250 - 300 around town
Is that comparable with what you guys are experiencing?

EGTs are very much the norm , see how it goes .
Good news about the ticker too , stop perving on young chicks eh

Yeah mate, only perving on old bags from now on

[threedogs]

after you do a few Ks lets us know what your comms are boost EGTs etc

Geeze mate I missed that post about the ticker.
Bloody lucky to say the least.
But also great to see the mods done. There is only one person which needs to be happy. That's you hey.

So yea sounds like a good outcome, and the rest of it is literally a few bolts so I think you could save costs and diy.

Thanks mate, yeah I was lucky! Supposedly, no damage and I'm feeling great!
Plan now is to drive the car this way for a few weeks and see exactly what we have. Then next step is the rest of the tailpipe and hopefully (once I have finished paying bloomin' hospital bills) a decent chip
Still tossing up between DP, Steinbauer and Unichip
Seems to be a lot of salesmanship and snake oil advertising in the chip game

Absolutely. And many people are ditching the chip idea and running your dawns needle valves instead.
I guess you choose the setup then and not
Replying on a bit of copper and plastic to do it for you.

Having the Dawes and Needle valve doesn't replace a chip Kallen. They do two different things. Well three....

As for the OP. When your funds are right for the rest of the pipe, don't bother with a muffler. I have a 3inch Redback zorst, it had the rear muffler. Removing this gave me the most responsiveness out of any mod I have done to my car. Complete pipe, chip, intercooler, high flow maf housing and anything else I have missed. It gave me more mid range power. If your looking for a chip, don't waste your coin on a new one. I will warn you now, you will be sadly disappointed in the amount they cost to the performance you gain. Just browse around on bumtree and evil bay and wait until a second handy pops up. I scored my DP for $500 a while back. And I have seen them go for less too.

Thanks guys,

I have been having a bit of a drive since I got the new 3" dump pipe and the car is definitely more responsive. I'm pretty sure the turbo spools up quicker than before.
EGTs are high - maybe these are normal figures on a CRD but when I'm cruising at 100Km/hr on a level ground, I see 350C or so but even at a slight incline (with cruise control on), the temperature quickly rises to 450C or even slightly more
At the same point, boost sits at 10Psi and climbs to 14-16 during those inclines
If you take off and accelerate hard, you see sharp boost spokes up to around 20Psi but these are instantly knocked down to the average boost for that speed/load combo. Must be the ECU doing its job

Mudski, thanks for the comments re the pipe. Won't I fall foul of the inspectors if I don't show a muffler in the pipe at all?

Try and find 2trollfam's thread on her ECU re map, expensive compared to a chip, but big performance gains
from what Shaz wrote,

Have you blocked the EGR that will take all thinking away from the ECU?
