RB Exhaust Question - Turbo Downpipe to N/A Presilencer

[My5ABaby]

I have the full RB n/a exhaust (header --> 2.5" presilencer) and I'm turboing my car. Will the 3" turbo downpipe bolt to the 2.5" presilencer?

I'm guessing no. For the T2's at least, RB makes two types of DP & presilencer designs. One type is the 3" DP & presilencer combo which is only compatible with the full RB exhaust system (turbo to tailpipes) - can't bolt this one up to a stock or stock replacement catback system. The other type is a 2-1/2" DP & presilencer combo, which is designed to replace everything from the turbo out to the stock main cat, and can be used with any stock replacement catback system.

You should email racing beat and find out if it will work with there 3in or 2.5in downpipe. I am trying to sell my 2.5in down pipe pretty bad. $50 o.b.o plus shipping brand new it is 135.00.

Yes Robert, it will.

That is the set up I was running on my FC.

I should have clarified perhaps. I have the full RB N/A exhaust, I just put the header --> presilencer in case it made a difference from the N/A downpipe --> presilencer.

So as a recap, the 2.5 to 2.5 will work.

Yes Robert, it will.

So as a second recap, the 3 to 2.5 will also work.

There. I recap'd it for you.

[My5ABaby]

Score. I presume the 2.5 to 2.5 will flow better since I would think the lip of going from 3 to 2.5 would be a restriction.

[FerociousP]

Just get a 2.5" and be done with it.

What Paul said.

I plan on getting a 2.5, but if I find a 3 at the right price it's nice to know I can pick it up.
