612 Exhaust and ECU w/o TOO LOUD

Rick L. from another thread: "Poor English but they simply ain't worth driving unless they have 12 cylinders! The music they make is very addicting."

I can hear it, but not well enough. And I wouldn't mind eeking a few more HP out for grins. What I would like to do is find the best possible compromise getting some additional performance out of her, improving the gorgeous howl from the exhaust, but not making the car antisocial or anti wife and kids. Don't want a LOT louder. But would like a little better exhaust note and don't mind doing a front to back exhaust replacement and ecu flash later this year. Would love suggestions. Maybe just buy a front to back replacement but keep the stock muffler?

 

I had a look at the x-ost site. Wish they made some hp claim. But yes, thanks, I could indeed be interested later this summer. I'm in line for a belt and gasket service first. So your exhaust just gives it a little more growl? Might be a good way to go. the full power package from a company like wheels and more is a LOT of dough. I found that link through another thread here but haven't seen much in the way of reviews on the package. Current exchange rate puts their stage two package at $25k. Prohibitive really.

 

There are some that do for the 360/430 setups. But yes, best I can tell none do for the 612. And I agree it really isn't necessary.

Thanks for the PM. I'll probably pick up your exhaust later this year. Car needs a great deal of work to get well sorted, belts, seals, gaskets, both intake and cam covers, adjust cams, bleed brakes and F1, clean fuel injectors, plugs. I knew this going in. I've never been the one paying for the service on the last two, but this time it's my turn. I'll know when done she's ready for the 10k min I intend to put on her in the next couple of years.

 

Thanks much. Appreciate it. What's involved in recalibrating the speedometer after the re-gearing?

How is that possible? What was the original gear ratio?

 

Mo, the Tubi is significantly louder than the x-ost? And you have just the mufflers and tips? With or without valves? Thanks.

 

I have a base '05, actual build was Dec '04. Very entry level and definitely no HGTC.

I'm really falling in love with this car, lemme tell you. I'm actually looking forward to spending a bunch of money getting her serviced. That's new. It's really funny. For me, the 612 was really hard to warm up to, but now that I'm driving one, it's hard to believe I put up a fight. Amazing car, and what bargains. Good gracious. 530 v12 hp with room for four, under $100k. Good gawd.

 

I need to drop by FOW tomorrow to discuss whether we're adding cam seals and intake gaskets to the service I'm having done. Probably will. I'll ask about the mechanics at that time. Mine's F1, not 3 pedal. Wonder if they have a dyno, don't recall seeing one. Would like to know if my speedometer is off by that much.

 

Wow, never ceases to amaze me. Didn't cross my mind to look for an app. Lost my range finder this year so need to check for a golf app as well. Bet they're almost free by now. Thanks for the tip. But how do you know how accurate "that" is? What's the deviation of cell GPS? How far off rails can I send this thread? Let's find out.

 

Interesting and somewhat embarassing update, not that I mind a little egg on my face. It happens. Just back from Ferrari of Washington, got a good look at the 612 from every angle. I simply assumed I had the stock exhaust. Well, uh, I already have Tubi mufflers and tips In the immortal words of Forrest Gump, "One less thang".

But that one less thang has been replaced with a few other thangs.

 

That, the aftermarket sound system and wheels are worth quite a bit to me. Also found out the intake gaskets had been done. Bonus. As I suspected, belts have NEVER been done. Rear tie rods or at least the joints are failing. Signs of a very slow f1 leak as well we need to isolate. None of this is a big surprise. What does surprise me is the number of successive owners that just didn't give a ****. This car is going to love me.

Coming from a 360 and 430 I'm used to a little less sound insulation I guess. We drove to cars and coffee with the windows down today and it sounds great from the outside but you can only tell passing an area where the sound bounces back. Its fine.
