De-cat pipe needed?
Hi all, I'm a new member and just bought a 2010 Stationwagon which I'm stoked about. I'm looking at all the threads here about De-cat pipes and removing the centre muffler etc, which I'm keen to do. Out here in New Zealand it's a bit harder to get these de-cat pipes and the freight is worth more than the parts as I'd have to get it shipped from UK at about one hundred quid for freight alone. I'm wondering, can I just take of the catted pipe from the turbo, punch out the cat material (thinking long concrete cutting drill-bit, chisels ? ) and fit it back on? Will this do the same thing? Cheers... Hamish

glad you're enjoying .. oh and so envious of your location albeit shipping might be expensive.


I'm no good on doing searches but if you have a go I'm sure you'll come across other threads where exactly what you've described has been done. and to the best of my knowledge has worked fine.

good luck.

Thumbs Up

Hamish, you can remove the cat, drill out the contents and re-fit. Save the bucks for more beer Thumbs Up --

Does the noise increase at the back? i want to hear some turbo Twisted Evil

And i presume mpg will increase and it will rev slightly easier? William

I can't say that I can hear the turbo more, but then it's been bucketing so hard here it's hard to hear anything else. Confused

I also cannot correlate increase in mileage/drivability since I also did the BAS v2 remap at the same time. --

Thanks for the feedback guys. Zedefender - those are great pictures from the 2012 thread... but I'm a bit confused as you've said you haven't done yours yet... - have you drilled it out but not fitted it yet?

Oh another question. When I remove and refit my prop shaft, should I be using a torque wrench to tighten back up? If so, does anyone know how tight? I'm a bit of a novice when it comes to these things - but looking forward to getting messy with my defender... cheers, Hamish

Ok so I drilled out the cat material - lots of mess and dust. Quite an easy job and results are great. I also got the mid-box silencer removed and a new piece of pipe welded in. Second day driving it and has a real noticeable difference. More pull, turbo appears to spool up quicker - as everyone else commented it would. Strange thing is it doesn't sound any different - I would have thought that removal of the mid silencer would have made more of a throaty but it hasn't... wondering if the decat downpipe would make a difference here vs me just punhcing out the material of the existing pipe (with the bulge in it). Someone suggested I take off the battery leads for 24 hours to let the ECU 'reset' to a new exhaust system... ? Anyway, sound aside I'm pleaased with it. Remap next!
