2010 Genesis exhaust help/hints/tips

[cmartinHFD]

i have a 2010 4.6 Genesis and im wanting to either keep the stock mufflers and remove the resonator, or keep the resonator and get a pair of Thrush Welded mufflers. either way, i need to know the pipe size. is it 2.5" or 2.25"?

If you remove the center resonator you will not see any gains because it is straight through design. Its essentially a resonated H-pipe. If you take it off the car doesn't get any louder but you get a tingy-raspy untuned sound when you rev the engine. If you are going for sound replace the rear mufflers with a quality 14in muffler. You should use 2.5 inch pipe.

well i had also thought about replacing the mufflers and removing the resonator as well. i want the true dual exhaust on this. it is dual up till the resonator and thats bugging me. i had a 97 Thunderbird with a 4.6 and i used the same approach and it sounded badass. i saw where some v6 owners replaced the resonator with dual glasspacks and deleted the rear mufflers. i thought about that as well, but im not a huge fan of glasspacks.

The resonator helps control unwanted exhaust frequencies, so i'd recommend keeping this on, or replacing it with a different one.

I'm not quite understanding your statement about true dual exhaust. The Genesis 4.6 has true dual from the factory. As already mentioned, the OEM middle resonator is a factory H pipe which has outlets for each engine bank.

Been there and done that.
First. Measure your own exhaust pipe diameter. It should be 2.25
Second. You can easily replace the central resonator with an "x" design resonator/muffler from Magnaflow. This will fit. No downsides whatsoever. The "X" design seems to offer minor performance improvements vs. the "H" design, though finding good research on this is difficult.
Third. Replacement of rear mufflers with aftermarket mufflers will cause a low rpm drone, which will make you crazy. Don't do it.
Fourth. There is one aftermarket muffler that relieves drone, it is the Dynomax VT line. It is the real deal - no drone and nice tone on the throttle.
Fifth. Fitment of the Dynomax VT is difficult, but it seems that the particular Dynomax with center inlet/outlet fits easiest. There is only one single model with a center inlet/outlet - that has a 3" pipe diameter. You will need to size it down.
Sixth. You can so modify a stock exhaust at a minimum cost, BUT it will not be cheap to restore it to stock when you sell the car. Do not discard your OEM mufflers as you'll want them someday.

well i plan on keeping this car until it rots so no worries there

I replaced my center resonator on my Rspec with a x-pipe with no gains just a strange exhaust note under acceleration. I had the stock resonator put back on and the rear mufflers replaced with 14in body Magnaflows and the car sounds perfect. Nice tone (not too loud) and very low to minimal drone. My wife even likes it. Be careful with those Dynomax VT's they have been known to rattle after a while.

Dynomax has a single moving part: a coil spring-loaded internal valve a true "Muffler Valve"). While it is physically possible for any such spring to break, and cause a rattle, in my research I was unable to find a single documented incident, but lots of internet rumors. My 2011 had 40K miles on the Dynomax when I sold it with no rattles.
Jaguar in its XK model has used a spring-loaded internal muffler valve somewhat like Dynomax's. There have been some instances of spring breakage, but the valve on my '07 XK (30K miles) is still operating like new. The valve is not serviceable on Jaguar or Dynomax.
Corvette also has a "muffler valve" in its high-priced optional exhaust.

Good to see people are still playing with their Genesis's.

I have dual tips, magnaflow exhausts, our secondary cat deletes, and an x-pipe. My first mod was to eliminate the mufflers completely, leaving the OEM H-pipe. The sound was amazing, but I couldn't stand the drone at 70mph. So I put on some Magnaflows that quieted it down significantly. Startup sounds VERY similar to a 350z/370z/G35/G37. That said, I recently replaced my OEM 2.25" H-pipe with an open 2.5" X-pipe. I missed the original sound, but did not want my drone to come back. The x-pipe was perfect. My 4.6L still starts up like it did with just the Magnaflow mufflers/OE H-pipe setup. It's under full throttle when I hear the difference. During highway speeds, I had a louder exhaust note, but no ear piercing or annoying drone. For me...it's perfect and what I was going for.

i looked up the Dynomax VT mufflers but they are $92 a piece if i get them through advance auto. im not spending that much money on mufflers. im looking at Thrush Welded mufflers or something that wont hurt my wallet.

will 3inch exhaust fit?

Here's just one and there's many more:

been a while since i posted on this. new job has kept me busy. i removed my mufflers and havent replaced them as of yet. i measured the diameter and its 2.25". once i get the funds, i know what im going to do. im going to also remove the resonator and replace it with a dual in dual out FlowMaster 50 series muffler and pipe it the rest of the way. it sounds badass as it is with no mufflers, so it should sound nice and proper when i do what i really want to do to it.
