Loud but not loud enough
Hey guys, I have a BMW Performance Exhaust (dualed-out) with a cat delete. You can see pictures in my garage.
It's very loud, louder than stock 335i and/or 335i with aftermarket exhaust IMO. At 3k-4k rpm, the sound becomes an unbelievable high-pitched roar resembling a screaming V8. I'm trying to find out a way I can have that same sound at 1k-2k rpm. What can I do? |

How does that help the exhaust note? While driving today I noticed the moment when the "heavenly" noise kicks in is at 3.2k rpm... I need that sound at 1-2k rpm !! |

Personally I have the OEM flat intake and after market cone intake, just the less restriction of air will make it deeper and I have straight pipes that are 3in from midpipe, y-pipe and eisenmann race muffler, makes my exhaust blow like from a straw (hollow), smaller pipes is like whistling from your lips (more high pitched).

@ OP
Video of your exhaust sound please! i'm still debating if I should go dual or just stay with an oem look (dual tip). @ Route 16 Your exhaust sounds awesome in person, when I heard it at Euro We Go it just made me want to put an exhaust on mines. |

At 1-2k rpm even my full eisenmann exhaust set up won't have that high pitch at low revs, it's only like what you experience 3k and above and WOT. IMO it might look weird at low revs, you want a race sound but aren't going fast.

For higher pitched sounds? Like full on race system? I say maybe muffler delete? But with that lovely sound, comes annoying rasp and rattle :/ the cone intake might just create that sound you want. Yes headers are expensive to fab but it might be more worth it since you like that sound. Try buying from supersprint or mmw. The reason I also recommend the headers because it might just add the sound you're searching for at such low rpms. Not to mention a few extra horses and a full free flowing exhaust

Which one do you recommend? How hard is the install? Labor cost? I'm looking to sell my car next year, installing headers will lower the value of my car IMO. Thanks for the advice! |

No problem, btw, do you have a resonator delete as well?

Oh I always though the PE was like the eisennmann exhaust with a resonator. But that is good set up, do you know what size the piping is ?

Intake won't really make the exhaust louder but you'll definitely hear some cabin noise from the intake. Headers will make it too loud and raspy. Not really much you can do at this point since you cut out the secondaries already.
