thanks for all the feedback guys. So it looks like my girl is willing to take over the payments on this next year and I'll be upgrading to a 335i or 535i. Not sure which yet. In the meantime I'll do the BPC tune, and what do you guys think of this intake?

If you're looking for higher performance without the need for additional tunes ... I'd go 335i over the 535i. Although the 535i has 300hp it's much heavier than the 328i. Frankly according to published figures ... a stock 328i is just as quick 0-60 as a 535i. |

My 128i with a N51 engine and an AA Header, AA Tune, aFe Intake, and custom 3" Single Exhaust netted me 241 WHP @ 217 Ft-Lbs.
So that'd be 283 hp @ 255 ft-lbs. However you wanna look at it. |

Bc i love performance but I also love obnoxiously loud exhaust haha Currently a 2.5 or 2.75 after the primary cats all the way to the tips, not sure what the stock size tubing is but I have that so wither 2.5 or 2.75 I really dont wanna any sort if mufflers, cats or resonators so i can be as loud as possible. Planning on gutting an extra pair of headers for a ful straight pipe, however not sure if I should bump it up to 3 inches or not? I’ve already lost enough backpressure plus probably more after that gutted header soon, so not sure if i shoulda stick with 2.75 or go up to 3 and maybe add an X pipe perhaps smaller diameter then bigger as it ends somewhere after where the 2nd cats should be |

^ damn that soudns really nice on my phone but audio is always different than in person
I was kinda thinking of running and X pipe ( for much needed back pressure) right after the primary cats then running dual pipes up until where the resonator would be maybe a little after and then go to the y pipe and then to the tips Just not sure what size tubing I should use I believ rn I’m 2.5 from the primaries back actually not 100% sure tho |
