I hear ya.

I'm really surprised there's not as much raspiness with an H-pipe. I would have thought there would be MORE compared to an X-pipe.

Sound-wise, based on that first audio I would go with H-pipe.

However, because we don't have a true head-to-head comparison recorded from the same cam - its really hard to truly know how they compare. I'd love to have an X-piped vehicle next to his and recorded with the same cam.

:iagree:
Need to find someone with X-pipe close to him and do the comparo. The placement of X-pipe also matters. Some install in center with extension pipes on both sides of X-pipe and others have done X-pipe at very beginning with extension afterwards, replacing the resonator.

The H pipe does sound better. How is the torque now with it in place? And did you remove the resonators? Awsome.

I like it! :thumbup:

The H-pipe mod is now a higher priority in my todo list :D

yes resonator was cut out (removed) & a stainless steel h-pipe with straight connector in middle (not arched) was added in the resonator's place - that was the only work that was done.. 3hrs labor.. $430 or something like that the shop charged.. Torque is almost identical - i cant feel a substantial difference - and this maybe because I feel like the HP went up by a bit.. I feel if I floor the car it breathes so much easier - exhaust gases flow out easier & guts down the line faster... The RPMs go up to 5,500 alot faster it feels.. it picks up speed a bit faster then before... maybe its just a feeling but it seems to be true.. i felt maybe before I had a little extra tap (torque) power in lower level rpm - but its almost unnoticeable (unless maybe your towing or something).. before it felt like it had a little more ummppp in lower RPM - a little more pull - but now it revs faster... with the H pipe I feel there is increase in HP... so i guess it evens it out??? --- maybe torque fell by a very very very small margin - but HP def increased by a noticeably margin... thats my feeling atleast... would have to dyno it to be 100% sure but this is what I feel driving the car for the past week....

You going to Bimmerfest? If so, we can record yours and mine with the same cam and at least get a better comparison.

BMW4.8is...roll with us ..were meeting at exit 11 south side rest stop on the trnpke around 6-7am...

Too raspy for me. How about the h-pipe without the resonator removed? Would that work?
