My phone is not calculating properly. I dug through some boxes and found my old TI-84 which does work properly. I finally got something with similar numbers to yours. It's really frustrating my numbers were so off. You definitely got the right answer.This is my Unbuild Journal and why we need an oil thread

Chiming in on this as I'm looking to get into the SS GB for the 63.5mm system--great thread. From what I read it seems that the 63.5mm section 2 is only really necessary if you are running high HP and other mods like cams, CSL intake, etc.?
My car is totally stock and I'm not chasing high HP, I just need to replace my stock manifolds (bad cats) and pass emissions. For an otherwise stock setup, if I run the 63.5mm manifolds (044001) and 63.5mm catted section 1 (044002), and stock section 2 and rear muffler, is that going to work just fine? Of course, I'd like the full system but cost is a factor. Seems the cats will bolt right up to the Sec2.
Any thoughts are welcome!Comment

The stock sect 2 is a great piece, and it will never be a problem running one, even on a FBO car. Remember, the SS 2.5" is exactly the same as the stock piece, just 3.5mm or 1/8" large diameter.DD: /// 2011.5 Jerez/bamboo E90 M3 · DCT · Slicktop · Instagram

Thanks for the feedback--but if I did run the 63.5mm sec2, would I lose power?Originally posted by Tbonem3 View PostComment

No. I have most bolt on mods, no cams, and I felt a little more grunt. I think Hassan demonstrated an 8whp delta but that was with 280 cams iirc.
The aftermarket sect 2s that lose midrange power are the Y pipe aka "Xpipe" style with no crossover.DD: /// 2011.5 Jerez/bamboo E90 M3 · DCT · Slicktop · Instagram

I have euro headers, euro cats (sec 1), and a scza. I didn’t like the rasp from that setup so I went with the dual resonated SS section 2. It quieted the car a not but I literally have zero rasp! The butt dyno is also very impressed.Originally posted by PSUEng View PostComment
