I have seen at least 2 trucks with the exhaust coming out the side of the rear quarter panel, sounds like a great idea to me.
Q: Do you need to have an aftermarket exhaust system to do that, because in the pictures there is no rear muffler?
Thanks

you don't really need that rear muffler |

REALLY!! 'Cause there is a huge hole or two in the pipe right before that muffler, and I noticed that it does not make any more sound than normal, I would love to just hack the thing off! |

Very common thing to do, with no ill results. Only problem is if you do not extend it to the end of the truck some complain of excess noise in the cabin at highway speed/RPMs. |

OK, then the question now is - who here has chopped it off? Any input on best point to start cutting (I suppose right at the muffler,) and any input on possible problems as a result?
If I do this it will be now, and later, when I get a beefed up stainless exhaust, I will reroute it through the rear quarter panel. |

I MIGHT, I will need to run it by my wife and the home repair monster that is always hiding in my garage whenever I want to do anything fun. Also, if I go, I might bring my brother along - with his Land Cruiser (FJ-62.) How many are planning on going? And are you a muffler chopper? |

the only down side I see with the through the fender thing is the noise driving on the expressways right next to the center barrier.
i'v driven vehicles that shoot it out the driver side and it kinda wore on ya |

So do the aftermarket exhausts have a beefed up center muffler to make up for the missing rear? Or are they just louder too? |

Would you want to make a up then down bend in the pipe so water doesn't get in the pipe?
I saw the most recent post ( the under shot with the cow shit over everything) and it would seem that the water would follow the pipe down to the bend and not be able to be forced or drip out. And when shut down, the remaining exaust and humidity will corode the pipe at the low spot.
Is ther enough room to remady this problen since it sure does look cool.

That's my cowshit  (its actually west-texas mud)
I have a drain hole at the lowest point. The exhaust exit is curved back and down. Haven't had any problems.

I too have the rear quarter exit. Just cut off the resonator and have a local shop bend a small piece of pipe for you. Noise isn't an issue, nor are center dividers. The difference in tone is a little nicer, but not too offensive. Make sure your hole is large enough though. No matter how you have it mounted, it will vibrate. |

Any issues with rust? On a former truck, I switched the stock exhaust to an aftermarket one which exited right at the bumper and I started to get rust on the powder coated (also aftermarket) rear bumper. |

A bunch of my friends have cut their tailpipes off right after the last hook, but I was told by two muffler shops that doing this is a bad idea for a few reasons.
When idling, the heat and moisture comes up and can melt rubber, dull paint, cause corrosion. When driving, the heat really dials up a notch and the same problems are compounded rapidly.
For $35 at Midas, I had them cut off the rear muffler and make it a straight pipe running out to the end of my rear bumper. In hindsight, the guy said he could have bent up a whole new tube that would let the tailpipe sit closer to chassis and tuck up out of the way and angle down at the end like Borla's design. Glad he thought of it AFTER I paid them!
Anyway, while simply cutting it off is quick and easy, doing it right is cheap and takes about 30 minutes. And for what it's worth, I haven't notcied any increase in noise. |

Right now I am thinking of cutting off the muffler, routing the new pipe up, then down right at the bumper so that it essentially exits at the same spot, but higher, and without the worry of breaking the muffler while off-road - which is what happened the first time, which is why I asked the question in the first place - thanks for the info.
Once I have it done I will take pictures. |

Has anyone eliminated the large single muffler and run low restriction dual mufflers out the back? I am contemplating this when my current system goes south. It could get a few extra MPG... |

hey jake...
i am glad you asked...i have wondered why no one ran duels on a disco as well...it was always our first move in my old hot rod days...
is it an issue of loss of back pressure, or would the increased flow lean everything out...?

I would think that the ECU would compensate for the reduced pressure and adjust the fuel mixture accordingly. |

I run MagnaFlow mufflers in place of the stock Rover mufflers. Performance is improved, sound level up just a tad (wife hasn't noticed increased volume or change of tone). It sounds pretty nice, not loud but low tone. These mufflers feature straight flow thru design. I paired this up with an "air force one" free flowing intake from Rover Accessories. It definitely runs better and doesn't sound like a sewing machine any longer. I first had the front muffler changed, broke it in for two weeks. I then returned to the muffler shop, had them cut off the back muffler. I drove it around for a couple miles to see how it sounded. It had a distinct howl/vibration between 2-3000 rpm. I then had a small magnaflow muffler/resonator installed where the rear stock muffler had been. So far I have about 2-300 miles on it and as it breaks in it sure sounds nice. Can definitely feel the improved performance. Its not a hot rod, but definitely gets up to speed much easier without gasping for air. Remember, internal combustion engines are nothing more than just big air pumps. Ease the flow of air going in and air going out and you win. Here in CA, there is a $2500 fine for removing or tampering with the catalytic converters on vehicles 1996 and newer. Personally, I don't think the overpriced exhaust replacement systems in the various catalogs are worth their high price. Grand total for my air intake and exhaust upgrades is under $550. Compared to the $1300 price tag for the complete systems.....use the money saved for rock sliders or your next set of tires or ome shocks and springs....just my $.02 |
