Depends on what your doing. It'll tick off your neighbors and attract attention from law enforcement. For racing, no big deal. If your planning to street drive it, please stay away from my house. I have to listen to enough noisy "egos" going by on the highway.  CJ |

Well, I have a glasspack muffler on mine. I guess that's like the last step before a straight pipe? Not too noisy or obnoxious, I have it going all the way out the back of my Volare. But yeah, I think a straight pipe would be kinda loud. I guess you could try running your exhaust without a muffler, then if it's too loud for you, you could install a muffler later. Or, you could do the exhaust cutout option. Ya pays yer money, and takes yer choice. |

Both of my slants I have ran with straight pipes have been quieter than my newer chrysler with a muffler. Its amazing how quiet a stock slant is. |

Both of the slants I have run with straight pipes have been incredibly loud, and it gets old quickly. Going down the freeway was something I did not enjoy with an unmuffled car of any kind. .02 ~THOR~ |

Instead of straight pipes why not just dump it right after the muffler? I am replacing my old Dynomax muffler with a Magnaflow and am just going to put a turn-down right after the muffler, dumped before the rear axle. It gives a nice aggressive sound without being too obnoxious. |

This is a very deadly idea. You risk infiltration of carbon monoxide to the cabin which will kill you in a short time. At the least, you will suffer sever head aches, and loss of judgment. Run a tail pipe to the bumper, it will still sound good. |

Or at least kick it all the way out to the side.Exhaust fumes can over time coat the underbody and do unkind things to metal/rubber etc. Lloyd |

Kicking it out to the side was my original idea (side exit before the rear wheel), so I'll have to take a better look at it. From what I could tell it didn't seem as though I would have enough ground clearance to do this (measured about 4 inches from ground to bottom of the pipe)....could just be a loss of judgement starting already Lloyd

I have a side exit exhaust on the duster and its just a single 2.25" out to a wannabe-flowmaster muffler which then turns 90 degrees and winds up just infront of the rear tire. This causes issues though with ground clearance, and exhaust gases are always making that tire and wheel look like poo. I am going to install the tailpipe next week so I don't have to worry about it anymore, and I will also be able to use the stock exhaust hanger location to mount the pipe, as of now I am using an extended bracket to hold it on, which I don't like either, looks kinda janky. ~THOR~ |

I will agree that safety is important. I will also agree that running it out the back is probably your most desirable option.

Any way to run it straight out the back without the need for the severe bends to get over the axle? Seems this is a restriction that I could do without, hence running a shorter exhaust with minor bends. PS, sorry for jacking this thread. |

The bends required to get the exhaust over the rear axle are not a big restriction, in my opinion. I do not have any data to back this up, this is just from my experience. I have had my Volare's exhaust out the side, and now out the back. I could not tell a difference. |

Seems this is a restriction that I could do without, hence running a shorter exhaust with minor bends.[/quote] Yeah, those bends would make a difference in back pressure if you were using ¾†pipe, but at 2 ¼†that little slanty dosen’t know the difference by the time those exhaust gasses have cooled a bit, and reach the backend of your muffler. You could most likely drop down to a 2†tail pipe and see no difference. Somewhere on the site there has been an extensive discussion on exhaust systems for a slant six, with or without, performance up-grades. These engines don’t pump a lot of air, therefore they don’t need big pipe. |

Occasionally I have seen exhaust pipes exit just ahead of one or both rear tires. Looks cool, and sounds cool. However this is something that makes no sense to me at all.First there is the fume hazard having exhaust exit under the passenger compartment. Second the ground clearance situation. I wonder how many of these set-ups have met their Waterloo after getting caught on an obstruction bending under the tire and being ripped off… Thirdly, and most important is the increased heat that the tire has to contend with that is dumped at its leading edge. That can’t help durability much… |
