The point was that the use of the OE style circlip connections on an IC itself, is of no restriction. Here is an adapter that shows as such.

Would it be possible to get the kit with some kind of adapter that would support the VRSF hot side and connect to the IC. I preferred to keep my HPF IC as this is quite effective even with the original couplers.
If the kit does not support the IC coupler, do you Rob have a coupler that would make it all work well? I think that my RB turbos would like the more free flowing hotside ;0)

You can use your OEM accordion adapter.

Okay and it would not be damaged in any way? I would still be able to go back to Original setup?

Can you please provide the link for ordering the high flow outlet?

Every upgraded outlet option available goes ranges from 1.75" to 2" at the turbo outlet and merges into a 2.5" collector at the intercooler. With the OEM connection, you'd then neck down to 2".

That's a bottle neck. Word it however you'd like but it's a restriction in the intake tract.

Your aluminum outlet here is a 2.5" OD (Outer Diameter) pipe with about a 0.060" wall thickness, no? So when you consider both walls (on the diameter) your part has an ID (Inner Diameter) of about 2.38", which is right inline with the adapter shown in the attached picture.

This is unlike the silicone options (vs. aluminum options) as they are measured in ID. So a 2.5" silicone size is TRULY a 2.5" ID, whereas a 2.5" aluminum size is TRULY a 2.38" ID. Unless you've sourced some special 2.5" ID aluminum tubing, then my apologies as this would not be the norm and probably is really in a Metric standard (if the case).

So as for the guys running these aluminum high flow outlets looking for max flow with IC's with OE connections, they are still good to go with an adapter as I've pictured. All they need is a 2.5" straight silicone coupler, and voila beautiful solution without having to condemn the otherwise high quality IC.

Thanks,
Rob

Thanks Rob
Can you advice where the 2,5" straight silicone coupler can be bought? And will it work/ fit the N54?

A 2.5" silicone coupler will not work without the adapter Rob mentioned. You'd have to buy that adapter along with the coupler.

Yes but where can I find the parts needed?

Reviving an old thread.

I'm getting some stage 2 turbos like pure soon with inlets. I don't plan on running more than 500-550hp. I'm torn on buying outlets. What you guys think? Is it really worth it? Very limited space to install and more heat too. I've done plenty of reading and see different opinions.

For the guys with a similar setup, what did you get out of having the outlets? Hp and tq all rpms or certain places?

[hidavi]

I had a bunch of other work to do down there anyway, so I took advantage that my subframe was down to do this install. Its mostly easy with the subframe already down, but I had a hard time securing the v-band clamp by myself for the front turbo. It would have been easier if I had someone to hold the front outlet y-pipe at at the right angle to so that I could work on securing the clamp. I got it using one hand to angle the y-pipe and a quick single-hand zip-tie action to get the v-band closed enough to actually put the screw through it. It took a lot of tries though by myself...
