Nice note!!
|
Nice mod. Sounds full race!
|
Perfect exhaust note.
What's up with that popping sound when you rev the engine? Does it go away after the engine is warmed up? |
Very Nice!
Can you tell me what size X-Pipe you purchased to accomodate the 4.4i? |
ya that popping/"rattling noise" when u reved it high, is how my 4.8 sounded when i pushed the gas almost everytime when i had straight pipes.
But after installing the x-pipe that sound went away and i all i got is a nice "brrrrrr" throughout the rpm range, and maybe the only time i get that popping rattling noise is at the very last rpms like 5-6k rpm. |
Sounds amazing

Supersprint does not list a system for 2005 and newer X5 4.4s. Anybody know what is different? |
