How to enhance MPE?

So I came from an 08 M6 with an updated x-pipe and tubi sport exhaust. Sounded amazing but missed the driving dynamics of the M3 so went back to the M3.

Went back to an 11 ZCP, added the MPE. Sounds good but really miss the howl of the M6 at low speeds, cruising around at low speeds. Those who have driven the V10 know what I mean.

I do like the MPE at 5k plus better than the M6. M6 fell a bit flat, where the M3 escalates

Any suggestions? I read that the x-pipe with MPE can get raspy. Don't want that. Thanks...

Compliment the MPE with test pipes and add a tune to turn off CEL. You wouldn't be more happier.

Depends on your budget, but you could try a quad resonated x-pipe

This is exactly what I did. I haven't installed it yet since I just got it, but ACM test pipes, factory x-pipe and MPE. This is the sound clip that sold me:

MPE and evolve sounds great, but why are they called test pipes?

Because "catalytic convertor replacement pipes" sounds illegal, which they are on public roads. Manufacturers of test pipes promote them for "off-road"/track use only, but in states without smog tests, it's pretty easy to forget to put the cats back on and stay in test mode 4ever.

My state requires an annual smog (exhaust) test. Will the test pipes be an issue for the annual test?

From what I have read on the forum installing test pipes will fail your annual "readiness" test. I am sure other NA members can elaborate on this.

I love the additional noise with my AA Green filter. It balances beautifully with the MPE. Everytime I stomp it, she rewards...much more than stock. I don't have to worry about passing emissions testing but I'm sure I fall a bit short of what test pipes or xpipe's bring to the table.

I have the same combo-- MPE with a Green filter. Thought about test pipes but I'm too lazy to bolt the cats back in every other year for the smog inspection. Plus, if I want more power I can drive my Viper...

Wait, doesn't the Akrapovic Titanium sound better because it costs MORE?

oh yes you have a point double the price and people will say it sounds more exotic.

If you want to enhance the overall S65 experience, leave the stock exhaust with the MPE and get a Goke carbon fiber airbox - it is truly awesome.

I think I'm heading down the path for an upgraded intake, Dinan or AFE. I'll get the enhanced sound I'm seeking without the emissions and exhaust modifications.

I'll try to get a picture posted of mine this weekend (and maybe an inside-car video). I ordered from their U.S. distributor out in Tampa. The airbox is not cheap (~$2,100) but it is my favorite mod so far, with the MPE a close second. I am running a Dinan elbow but stock air filter.

They are called test pipes because they are used to "test" the functionality of a catalytic converter as opposed to having a straight pipe there.
