Best exhaust upgrade for e53 3.0???
 
I love my X5 exhaust upgrade.

(Not exactly the most economical).

(This is my 2011 35i that replaced my 2001 3.0i)

I do love the exhaust note. Wife calls it exhaust therapy. I agree.

Here's another where I rev twice and open the exhaust flap for the second rev.

You'd think you can modify the 3.0i exhaust to match the 35i. You won't get quite as burly of a note but the first video above is just idle and it's the same basic engine when turbo not spinning. Wonder what it would take to retrofit e70 exhaust to e53. (thinking junk yard grab).

LoL.. You shouldn’t have to worry about that. My setup is quite a bit different than a stock E53. The dual muffler system should definitely deaden the sound, while keeping it tuned vs just using resonators.





I have a very large supercharger connected to my intake manifold LoL.. But before I had my blower, I had an aFe cold air intake. It worked great for what it’s purpose was!

thanks for the suggestions, I will keep you updated and this week I'm doing the wooden trim wrapping to gloss black and upgrading to the xtrons radio unit first

Happy now I'm conteplating Vibrant Ultra Quiets lol

I did measurements and you were right the Dynomax Super Turbos will not fit

Vibrant Ultra Quiets would fit much more better

I had a feeling. It’s pretty tight back there.

Those Vibrant Ultra Quiets are pretty much what I suggested in the beginning, just in a different brand. I don’t think the brand would make much of a difference being that their the exact same design. But, you never know. The Vibrant brand seems to be a good quality part, although I’ve never used it. I’ve used the other brand numerous times.

I got two Super Turbos to fit in the stock space in the back of an E30. I would be very surprised if you can't get them to fit.

The standard length for a Super Turbo is 14", which is only a quarter inch longer than the Vibrant Ultra Quiet.

Don't forget that the mufflers don't need to be flat, also. You've got a bunch of height in there to work with if width is an issue.

that does sound nice, I have a theory now that my whistling sound might be a crack in the valve cover gasket which makes me want to replace this as I haven't done it in awhile, have you heard any reviews on the aluminum ones?

I'm leaning towards just going the BMW OEM, those usually already come with the gaskets and such installed on them too if I recall correctly.

I used the OEM from FCP. I'll be sad if I have to replace it but if even lasts a couple years will be worth the $390 savings

Andrew I finally found a video of the same exact whistle btw, could be the alternator?

Definitely can be. Easy to test with a cold engine since no coolant pump pull the serpentine belt and drive a course you can repeat the sound.

Mechanic stethoscope can narrow down sounds such as this.
