#7 E90 328i quad exhaust set up

My 7th exhaust set up since I've had my E90. Primaries are still in, the rest is oem midpipe size up to the control arms area then it gets smaller to 2 inches all the way through to the tips I guess. Subjective tolerable drone. Back pressure = whatever to me. I get 450 miles to the tank and I'm happy with it. Only revved to like 4K.

Sounds nice! 450 miles?! I usually get around 350 on a tank, and I do mostly highway. Does the exhaust set-up alter MPG that much?
Only time I got 450 miles out of a tank was when I babied the crap out of the gas pedal to see how many miles I could milk out of the car.

It's pretty consistent. The more I remove anything exhaust related the MPG rises on my car. Cone intake, oil change every 7k. Babying the throttle on the highway I can get 480 miles a tank. I drive 100 miles a day around the bay. Mix of street and highway.

A shit load of mods just waiting for install and arrival (bumper/hood/headlights/trunk/taillights/diffuser) then I'll do another photoshoot.
If anyone wants to buy my oem tails that are painted cherry red, they'll be for sale eventually.

I went to this guy on e46 forums, with 76 mm (3in). I think it'll fit (4) 3.5 in tips perfect flush but didn't want to risk the CF diffuser.

sounds amazing to me. Is the drone in the classic 2-2.5k RPM? Can you do some videos inside. Also, maybe some decibel readings?

Damn dude, it seems like you're theSME(Subject Matter Expert) for exhaust mods to do it 7 times! I want a quad setup, but I decided to stick for an OEM look, but if I do get the SC, maybe I'll change my mind.
