Hello!
I bought a w212 2010 E63 6.2. I would like to upgrade to have more performance. I going to divide the tuning in two steps: 1 (Ecu, airbox and exhaust) and then the second step of supercharging (weistec). I would like to have some tips about the first step. How is the weistec exhaust? How does it sound? Does someone have it on his car?

Is it better to have all parts from weistec?
I am writing from Italy so please reply with a simple english! thanks!

Very expensive but Weistech is a proven company. Very expensive. You can get great sound and performance with resonator and cat delete and longtube headers for half the price.

Sorry to be an *** but if you want to tune - sell the 6.2 car and then buy either a 5.5l turbo or the W213 4.0l turbo.
MUCH easier to dial up boost than go down your path.

Might be easier but much more expensive if getting into a newer car. Or maybe actually breaks even if there is some cost/HP calculation based on OP's objectives?

Thanks!

Lots of cheaper options out there, personally I'm running Becker Longtubes with Dual X-Pipes and full race catback for under $2K.

For tuning I used @eightysixtuned, via HP Tuners and remote data logging. He's a member here and very knowledgeable with these cars.

That sounds really really nice!! No turbo car could ever sound like this! thanks for sharing

Sounds great but where do you live?
In most places (?) that sound level will get you pulled over all day long....

if you want to reduce the sound without compromising the performance you could keep original mufflers or keeping a small cat (100). Surely it is very loud! XD

WOW That sounds completely amazing.

Texas, it's pretty quiet at cruising speeds and only loud when you open up the throttle.

I agree, some cams would make it sound even better.
