First question is obviously: Should I do it? Is it worth the hassle/expense? Have 456 owners here done the swap? 2nd question: will it cause CELs and screw up the diagnostics? My f355 is a 95 thus OBD1 so I never worried about any of that stuff. However, my 456 is a 97 so OBD2 is a different animal. I don't want to swap it out and get a Christmas tree on the dashboard. 3rd question: Am I better off getting the Bradan pipes which are continuous single pipes OR is it better to put an X-pipe there similar to what Larini makes? Are there any benefits to an X-pipe? How is the exhaust flow inside an OEM resonator? Does it criss-cross or are there 2 individual channels in there? Any help would be appreciated.

I'm interested in seeing what people say on this because I'm debating the same thing for my 456m. Love the car, not a fan of the lack of sound. Sent from my iPhone using Tapatalk
My 355 is pretty much the loudest Ferrari in Montreal so I kind of enjoy the quiet of my 456 but it's a little "too" quiet. A little subtle oummpfff would be nice
I'd recommend the Tubi; plenty of noise when you stand on it, but not annoying at steady speeds or low revs pottering around town. My kids love going through tunnels with the windows down. I think you can hear a lot of different sounds on youtube. Tubi: https://www.youtube.com/watch?v=nlyAPJXEIa8 Larini from Formula Dynamics: https://www.youtube.com/watch?v=2RchhuMzx0M
Just like with the Maranellos, the straight pipes will give slightly more hp and torque and are pretty loud with aftermarket exhausts. Some owners prefer the sound of an X-pipe with all the exhaust pulses mixed together and less chance for resonance. The difference in hp and torque between straight and X-pipes is not normally noticeable with a posterior dynamometer.
I have an x pipe and a aftermarket mufflers on my 550 and love it. I feel the sound is still classy in that it is not too intrusive but when you step on it, you know what you're riding in. I'd like something similar out of the 456. Sent from my iPhone using Tapatalk
I bought the Bradan straight pipes but they're not fitted yet. I chose them over x pipes for the hp increase and the fact that I think keeping them separate sounds better, more special. Most people on this board seemed to prefer them at the time. Another reason is that should there ever be a problem with the engine or engine management is that with straight pipes you can easily see which bank.
LOL Considering exactly the same problem for my 456. Will probably be doing something about it in the next 2 weeks.
I faced the same problem with the sound (or lack of!) so purchased a Bradan straight pipes for my 456M. Before I fitted then I also managed to pick up a set of 456M Tubi exhausts too. Initially I fitted both at the same time and it was just too too loud. I had both on for an hour before I changed the central pipes back. My mistake was that fitted both. Either one or the other would have been perfect. Both is overkill. Decided to keep the Tubis on as they were harder to fit! The thought of changing them was beyond me on that day. Anyway planning to sell the Bradan pipes so if anyone is looking, PM me.
I have Tubi exhaust pipes, not very musical. I added the Braden resonator delete- easy installation about 30 minutes ( I have a hoist). Magnificent sound,like a V12 ferrari should. Magnificent back rumble when off gas. No lights since installation, Cat controllers went off once but due to moisture not pipes. Just needed sealing and drying out. If you want it softer drive in gear 5 or 6. ,But why???
In November 2003, Ferrari eliminated the central muffler/resonator on the 575M and began installing straight center pipes. Straight pipes continued through the 612 and 599 series. So we know which way the factory voted.
I hated the separate resonator delete pipes on my 99 456M (I believe the 456M have a slightly different ignition sequence than the 456). I ran the stock mufflers back then. It felt like it lost 20% of the low rpm., and it sounded like two old inline-6 Mercedes from the 60-ies. I also ran cat delete pipes then. The Stock rear boxes takes a lot of the sound away. Later I made the two pipes into a "boc" micing the pulses, and the low rpm throttle response and power came back! I felt it instantly. Next step was to add two Fuchs rear mufflers (straight through With minimal damping). That meant I had in essence almost no silencer at all. It sounded way way to muck, and the sound was not very good either. At the same time, I got to test the previous owner of the Fuchs mufflers' own 456 (not a Modificata version). He had the Stock cats on it, Stebro "x-pipe" (a foot long oval pipe) and no rear silencers at all, just a Y to get four tail pipes. It sounded fantastic, with minimal drone and a good musical touch to it. So I went for that setup on my own. Removed the cat delete pipes, and put on stock catalyzers, stock resonator/center muffler (which has a build-in cross pipe in it) and two new Y-tips insted of the mufflers. The sound became great and the SLOW DOWN dissappeared. But still, it was too quiet in the high rev range. But good at ide. So the last thing I did was to get a Stebro X-pipe and the car was fantastic after that. No drone, just a beautiful Ferrari classic sound in all revs and situations. Then I sold the car. On the 550 though, It seems like straight or H-pipe is better. But it all depends on what kind of muffler it has. The original mufflers take a lot of the drone away.
* What makes enough noise for one person is too quiet for others. YMWV * I purchased and installed just the Braden resonator delete pipes on my 2001 456M. Stock mufflers. * Enough growl for me at low speeds; very easy to talk with wife and boys in the back at any highway speed. Family didn't even realize the change. * No annoying noises drone for 400 plus mile rides. * If you personally drive long drives, then even "loud" beautiful Mozart noise sucks by the end of the drive...especially if you can't turn it off. * I noticed absolutely no sense of low or slow throttle response with the straight pipes. * To me, YMMV, the straight tubes with the stock muffler suits the 456 character. * No CEL lights lit up
Stu- Yup, I would expect nothing really noticeable from the posterior dynamometer, just a change in engine note and slightly different tones depending on whether straight pipes or an X-pipe is used.
Right, Terry. Based on Stephen S's research: http://www.ferrarichat.com/forum/135802129-post24.html I had Classic Coach fabricate Burns Stainless 321 stainless steel center straight pipes for my car seven years ago... . Image Unavailable, Please Login
Barry- At least I lucked out on one thing. Missed the steering position sensors by about 10 serial numbers, but did get the factory straight center pipes.
I have an X pipe and Tubi back boxes on my 01 456M GT and it is like 12 Angels having sonorous sex. Can't be happier with the sound, the mixing of the tones from both banks is essential with the X pipe and the Tubi's are an excellent off the shelf choice for a balanced and growly note. There is no drone and I get constant compliments on the sound both while idling, low speeds and under load. We do a lot of cruises and guys will be eager to follow behind me because they like the sound so much, plus the rowing of a proper gate. https://instagram.com/p/61BlbBJZd2/ http://youtu.be/swBG9BOhdvA http://youtu.be/DtcQGwt2Bms Image Unavailable, Please Login Image Unavailable, Please Login
Anyone know if there is a difference between the 456 and 456M or do the resonator delete pipes fit on both?
One is a slip fit, the other a bolt on flange, I do not rmember which is which but Just check with Bradan. I have the Bradan straight pipe on my 99 456MGT. The sound is just right to my ear. Nice jurgle but not at all annoying. Keith

I would love to fit my 456M with an x-pipe that incorporates a pair of small resonators, to refine the sound and be sure the noise stays in keeping with a luxury GT. At one point, a company called Hughes Supercar Services in Australia was making such a pipe, but they seem to have disappeared.... I already have the Larini rear boxes, and they sound terrific, though they do quiet down as you move up the rev range.
Braden pipes on mine, along with Tubi's.........obnoxiously loud, but I like it. The wife...not so much. Scott
There is no one best answer for exhausts. Tastes differ too much. So it ends up being trial and error.
