X pipe mod. done. Pics inside
 

Today made the X pipe mod. Total cost was 95 euros, and for this price I can´t find a better mod :thumbup:
Sound is slightly different, with a deep growl at idle and while accelarating you can hear a ponouced bass sound, I just love it. When I got home, stayed inside the garage playing with accelarator :thumbup: the sound is great, I don´t know why BMW does not make it like that from standart.

The X pipe was made by some exhaust pro guys, fit and finish look fine.Here´s some before and after pics.

Looks well mate, notice the difference theres seems to be less of an 'X' formed. Was there any reason for this? And the overall design seems less fussy in terms of welding and install.

I know you have not had it long but have you noticed any 'pops' or misfires especially under acceleration from standing?

mine pops all the time when i let off the gas at a higher rpm. Love the sound!!!

Any difference in performance?

Glad you are happy with it! On to the next mod :thumbup:

Has you said I didn´t have enought time to check this up, but tomorrow I´ll have a longer ride and try to see other minor differences.
Regarding the less "X" form, I also notice as soon as i saw it, and I belive this might give me some raspeness at high revs, it´s almost like a misture of straight pipes with X pipe, but I hope this wont happend, don´t like the rasp sound at all. I might drop the Remus exhaust within weeks, this will give the final sound I´m looking for, not to loud and intrusive and deep/bass enought to put a permanent smile on my face :)
Tomorrow will make a sound clip so that everybody can have an idea of X pipe sound.

noncom23, didn´t notice any difference yet, but this modification doesn´t give 0,00000001 HP ;) it´s merely an engine/exhaust sound upgrande.

Seven, when your exhaust is complete please let us HEAR the system

Thanks.

mine sounds great, I definitely recommend either X-piping it or straight piping it. Mines straight piped.

J.Seven, have you made the sound clip after X-piping ? Would like to hear it.
