Ya that has to be what he is talking about. Well for the TII, I believe the RP is only 2.5" and RB has a 3.15" DP setup. For NAs I believe they are the same but the RB is SS.

Thanks. How about the length? Are they pretty much the same? Coz I wanted to know if the RP will bolt-up fine with my RB pre-silencer. BTW, I am asking about a turbo DP.

The Bonez product comes in 2.5", it is stock replacement. The RB product requires other RB parts and comes in both 2.5" and 3". I don't know what configuration you have since you have the RB silencer, but not the downpipe. The racingbeat is stainless while the bonez is mild steel. I think the racingbeat is better value if you go with the DP, silencer/midpipe than the bonez going with DP & MP. Normally if you just want a DP the RB is not an option.

I have the RB 3" DP!

You need the pre-silencer to bolt up to the cat, or i had a custom 3" midpipe made to run from the DP to the bactback.

I currently have an NA with RB headers but I will be converting it to turbo soon so I needed to get a downpipe in place of the headers. I just checked racing beat's website and they do have a 2.5" DP for $90. I didn't find a 3" though.

**** sorry, I was assuming you had a TII. I did that recently the other way around, were a guy stated that he had a TII and I posted thinking it was an n/a. Are we doing an n/a block or a turbo block? From what Aaron Cake has said, a TII downpipe won't nessisarly fit on the rest of the n/a exhaust, so you'll have to do your own research.

Thats ok Snrub. I am keeping the NA block but I'll be using most of the turbo parts including the intake manifold. I should be fine with the exhaust. The DP should bolt between the turbo and the pre-silencer.

dr0x, that's ok. I realized that I don't need 3" anyway. I currently have 2.5" piping so I'll just stick with it for now.
