Help me choose which BEGi DP
Help me choose which BEGi DP
Nissan T25
Enthuza 2.5 exhaust
Goal: ~200 whp
I bought the BEGi-S downpipe when the prices were going to increase (much to my dismay, they are on sale now for cheaper than before
), however yesterday I bought a BEGi SS divorced downpipe as well. Now I have 2 DPs.
Can the T25 w/ BEGi-S DP handle 200whp or is the DP just too poor of a design? Or should I go w/ the divorced DP? Will it really make that much of a difference? I've never seen dyno runs that compare non-divorced to divorced DPs.
Or should I just get a welder to modify the BEGi-S to a bellmouth?
I didn't realize this at the time of purchase, but the upper part of the "S" DP is only 2 1/8"! I was told by BEGi that it was 2.5" DP when I bought it. I assumed that was the entire DP piping size. It only swages to 2.5" at the outlet. Is this how all BEGi DPs are (super small DP inlets)?

If you are hurting for money and want to sell one or the other, you'll obviously get more $ for the nicer divorced gas one and the BEGI-S DP will probably do all right for you.
That said, if I had both sitting in front of me, I would absolutely choose to use the nicer divorced gas one. The design in many ways (not just that the wastegate is divorced) is better. Sell the S DP to someone piecing together a budget kit.

I think the S pipe is such a horrible design (reminds me of the original greddy) that you would be wise to go with the divorced pipe. No matter what your power goals are, spool is still important.
Honestly if it were me I'd sell both BEGI parts and get FM's DP. I think it is a better design in a lot of ways. If I could do over I would have gone FM on my DP.

The BEGi-S downpipe is capable of handling up to 220 whp (that we have actually dyno'd). I would not worry about it. You will probably get more money for the SG DP than the BEGI-S one as we have changed the design.

lol Feel the love in here.
Like almost every other owner here that has felt boost in their car, you're going to eventually want more, so then you're going to want the better DP. The SG DP is a pain in the **** to install, but it's worth it, so I'd say do it once and be done with it.
So I 2nd the suggestion of selling the S to someone building a budget build. I just so happen to have a friend looking for one if you decide to go that route.

Do not ever type to my bitch like that again. If you have a problem with him, it goes through me, and I'm fairly certain that unless you want my little faggy dog to make a collar out of your spleen, then you can stfu and never bring your horse-**** disrespect and ------ry to this forum again.

Cast upper section, mandrel bent lower halves. Zero welds to fail. O2 sensor bung in a useable place? Fits properly? So where exactly does the design fall short?
We know that there is at least one ~400whp-ish stroker running about using that DP, so it can make big numbers. The dyno charts showed pretty decent spool.
Better on paper doesn't mean better in reality. If BEGI is going to claim what they have is superior, prove it. Otherwise it is just marketing BS.
I still stand behind my idea to sell both BEGI pieces and purchase the FM DP. The user is looking for modest numbers, so any edge BEGI has (imagined or otherwise) is moot. So what's left? Fit. Ease of install. Durability.
