Hi Guys 2003 575 currently has delete rear mufflers replaced with 'Tubi' straight through rears which is ok sounding but my question is this has anyone replaced the centre pipes silencer / resonator with straight through so effectivley system is un-silenced from cat back ? is it too much or is it heavenly Thanks Tim
I have a somewhat similar setup on my '98 550. I have a pair of Braden straight pipes for the mid-section and a pair of modern Tubi tailpipes. The Tubis are the newer street version ones (not race version) and have the "575" stamped on the bottom of them. I like the sound of them a lot. Not too loud, yet a full "brrapp" sound while under hard acceleration. Some nice burbling and the occasional light popping sound when downshifting. And no irritating droning sound while cruising on the open highway at 65-75 mph. I can listen to the radio or have a conversation with a passenger at highway speeds. Not sure which Tubis you have. Yours might be much louder though with dual mid-pipes if the Tubis are straight-through with no muffling. .
I have a resonator delete, Tubi straight pipes and Nuvolari mufflers. I have alternated the Tubi and Nuvolari solutions. With the Tubi, there is no muffler, just straight pipes. While a great sound, it is loud. Fine at speed, too loud at idle or low speed.
I have the resonator delete with Bradan straight pipes, I had the Tubi mufflers, which I used for a while , but became way too loud , and recently put the factory mufflers back on, but now way too quiet !
Sound like I have opened a can of worms ! Hehehe Sound is such a personal thing when it comes down to it I like my cars to sound raw when accelerating with the full V12 orchestra But mellow when cruising at motorway speeds I guess I could try straight pipes from cat back and see how she is currently no back boxes / silencers (mufflers you guys say) Is the centre silencer (muffler ) very restrictive ? Does going mufflerless cause any running issues ? Boy I thought this was going to be an easy decision seems not
Tim- The center muffler is a cork. Straight pipes (or even X-pipes) really open her up and increase hp, torque, and exhaust music. If you do fit a set and they are too loud, there is always a market for them and you will not lose too much money. X-pipes will give slightly less hp/torque, but some people prefer the sound. Bradan is a good source for straight pipes, but they are easy to fabricate, as well.
Hello Terry, My 2003 575 in which I first replaced the center muffler with an X-pipe... and now with two straight pipes, no X... I like the two straight pipes more than the X... Better high RPM rev... Alex
Alex- There is no doubt the straight pipes provide better performance, but some owners like the X-pipe sound better, even though V12s do not need the cross-pipe to extract exhaust gasses. With six closely spaced exhaust pulses per side from the two straight sixes on the same crank, exhaust gasses are extracted just fine with straight pipes. One of the reasons Ferrari went to straight pipes in Summer 03. Free horsepower and cheaper than the center resonator/muffler, so two benefits. All that X-pipe stuff is a legacy of 90 degree crank V-8s. Ferrari's flat (180 degree) crank V-8s do not need X-pipes, either.
Exactly... Very well explained... I actually got the pair of straight pipes from my friend Alex Zhan's 2005 575 GTC cause he went all the way spended big bucks from balanced headers, high flow cats, center pipes to rear mufflers from SUPERSPRINTS... The OEM pipes fits my 2003 575 with rear pair of TUBIs working just fine... Alex
great info and help guys I think straight through centres is the way dont want to play with cats and manifolds but would like a beautifull sound my build number is 4963* so i presume its the muffler version certainly looks like a bulky muffler underneath to me which is best pipe to fit 'quality & price' Larini Supersprint Tubi Quicksilver any links and suggestions welcomed Thanks T
Hi there, For my friend Zhan Alex's 2005 575 GTC car, the entire full set of SUPERSPRINTS from balanced headers to high flow cats and all the run down pipes to the rear mufflers, costed over USD$10K labor work and ECU reprogrammed included... Lots of work to it... I drove the car several times back to back comparing to my own 2003 575 3 pedals car... The GTC car(After all the mods) did feel slightly quicker, and when the engine RPM is pulling, it gets to redline a little quicker... Sounded brutal and wild, but not smooth... Later they reprogrammed the ECU to take out all the warning lights and smooth out the engine a bit better... When we both took out both cars to local freeway midnight to do a 60MPH to 160MPH from 3rd gear to 5th gear... The GTC car does get ahead of my car by about 5 cars length, (eye vision judge, not accurate...)... So we drove both cars back to back all night... It felt good and I like it.... But, I don't like it enough to spend over $10K, yet reprogram the ECUs to match the entire exhaust system and trick the warning lights... So to myself, not worth the money to go with it... To clear the point here, it's just my own opinion, nothing against SUPERSPRINTS, and or the ECU reprogram people, and the shop who worked on the GTC car... Mr. Zhan Alex the owner, on the other hand, he loved it completely, and thinks every dollar he spent worth every penny out of it... and can not stop talk to me to do it on my own car... Alex Lin
And again, So nice of Mr. Zhan Alex gave me the pair of the OEM GTC's center straight pipes with the Ferrari logos on for free... If these pair of center straight pipes work good for Ferrari s.p.a.... they definitely work good for me.... Alex Lin
Interesting reading! One (maybe dumb) question: Are the cranks and the ignition "pattern" the same on all 456/456M/550/575 cars the same? I remember to have read that Ferrari changed the ignition-pattern don't know the right term for it) on the 456M? After playing with my 456M with different exhaust combos, I have noticed that to have much restriction in the front of the system and less at the rear gives a much smoother engine and exhaust note. X-pipe vs. straight ones were also a significant change in low rpm power. Not sure if this is the case for the 550s and 575s though.
456M has a unique firing order. Head design on the 550 and 575M is considerably different from the 456/456M, as is the intake system and cams. All of them are still two six cylinders on the same crank, just like the Ferrari V8s are two four cylinders on the same crank. American V8s are four V-Twins on the same crank, and that is why an X-pipe can help hp. The factory went to straight pipes on the 575M in 2003, good enough for me. Mine sounds great with OEM straight pipes and OEM SA HGTC exhaust.
Terry, I have a 95 456 with stock exhaust. Haven't found an aftermarket center-straight pipe. In your opinion, any downside to having my local muffler shop just fabricate a replacement? Thanks ......Mark in Houston
Mark- Absolutely no downside. The 456s are really simple to change because it is just two pieces of straight pipe plus connectors. Parts catalog page is from Ricambi's online catalog for the 456M, but the 456 exhaust looks just like it. Image Unavailable, Please Login
Thanks Terry: The 456 is slightly different in that it has flanges and gaskets and spring-loaded bolts, where the 456M has clamps. That was my concern, ie that eliminating the springs might cause something else in the system to crack. But, now that I see the M uses just clamps and everything else looks the same, I don't see any problem with eliminating the gaskets, flanges and springy bolts. The M is supposed to be better, Right? Thanks again......I didn't know the M used clamps......Mark Image Unavailable, Please Login
Mark- Yup, should work. I think a lot of the old doughnuts, etc, was a holdover from before stainless exhausts. You needed something to plug the parts together as they corroded away. I should not have been lazy and converted the 456 exhaust to a jpeg.
Yes, exactly, I had a 97'456GT years ago, and now keeping the 2003 456MGT, both engines runs and feel quite differently and sounded differently too... The 456MGT runs a lot smoother and quieter than the 97' 456GT, not much differences in Power and torque, sometimes I actually felt my earlier 456GT runs quicker than the current 456MGT... I am not modifying the 456MGT's exhaust cause often I drive the car with my two kids in the back in long distance from LA to Vegas to Utah, and kids often fall asleep... so, it's good to keep it quiet... Alex
Hi Has anyone on a 550/575 us a cat delete/ test pipe with stright pipe in center and stock res at the rear AL
