Wanted to buy some catless downpipes for my 135i

I have ar catted ones but I would like to get catless ones for some testing to see if they make such a big difference in power.

Doesn't really matter what brand as long as it fits RHD cars.

Let me know if you have something.

IMO brand is not that important for DPs and the power increase is not staggering, biggest increase is in noise. New VRSF DPs are pretty cheap. Regardless of new or used I would get them fitted professionally as it is a PITA to fit and can lead to a string of problems if fitted incorrectly... VRSF supplied and fitted = circa $1200

Sweet... post results please

[martymil]

I will be making a thread about the ar catted vs catless with real world gains, pro's and cons with a full write up

As far as I know nothing like this has been done on the forums and these questions keep getting asked over and over without a definite answer without proof backing it up only hearsay.

So look out for it and I'll post a link later

The write up will have to wait got a hpfp problem, should be sorted out some time this week

Hey mate, where did you get your catless DPs from? Been searching for some for a while now

[martymil]

Someone pm me and they where local and needed money fast, pure luck.

Damn man, that's lucky
