Slow E63




"The thing is though, I recently changed my intake manifold bolts. Could this perhaps be a different leak? The sound is really annoying."
Did you also do the gaskets or just the bolts, was there a previous issue or was the replacement just for entertainment.
Whistle noise in any engine is not good as uncontrolled air entering can act like a cutting torch and damage internals, especially valves and pistons, rings etc.
E63's are not slow.
Yes the straight pipes are going to be louder, giving you a false sense of power though.
The E63 is not a slow car, but very different in power delivery as compared to a E55, if I owned a E55 I'd have never brought a 63 (I came from a FBO e92 M3 with 300tq, but it walked my friends SL55 on the highway), simply because once you have that mountain of torque so low in the rev range anything else is going to "feel" slow regardless of the amount of horse power.

Now im doing str8 pipe instead of xpipe cause i get no burble on deceleration with xpipe.
As for burble, I lost that as well when I changed from h pipe to x pipe on my 63, but gained it back when I got long tubes and a x pipe, and it's LOUD.
Keep us updated on what your changes yield. I can't lie I wish the E63 TT was in my price range at the time as well cause that kind of torque is amazing.

1) Stock resonator
Back-Pressure Loss: None
Torque: Perfect
Sound: Awful
2) Deleted resonator and put Xpipe in its place
Back-Pressure Loss: Some
Torque: Felt loss of lower-end torque
Sound: Good
3) Deleted resonator and put straight pipe in its place
Back-pressure Loss: High
Torque: Even greater loss of low-end torque than xpipe
Sound: Amazing
Is something not adding up here? Why are straight pipes destroying my low end torque?
The only reason I'm not doing headers is because they're like $5000.

The gain and sound from Longtubes and a tune is highly noticeable, did all mine for slightly over 2k (tune included), which isn't so bad when compared to most.
But as stated, charcoal filter removal, better air filters, Row air box mod and a tune wakes the car up pretty good also.

All in all my American Racing Headers xpipe and tune came in around $2500.
