Oddball exhaust question

    Lemme preface this by saying... This is only a thought.... I do not actually intend on doing it..... More of a study to see what would happen...... and to see how badly I get flamed :spank:


    You all no doubt have seen an import racer. The cars with the shopping cart rear wings and the "no springs" lowering jobs.

    A honda (or any other FWD racer) has the muffler all the way at the rear of the car. When the tip size isn't too nuts I think the mufflers actually look pretty cool. Nice shiny thing tucked under the rear of the car.

    My question is..... How would a V8 car sound with two of these things tucked up under the rear 1/4 panels?. Would moving the mufflers to the very rear of the car hurt performance in any way? Would probably do wonders for ground clearance. Does this even sound like an idea worth trying or am I just a dork??? :Dou:

    I noticed the current vettes have a similar exhaust.

    Most of the tailpipe setups I have seen for my car just don't do it for me (2 pipes sticking straight out from under the bumper, hanging out too far) or the old school straight pipes with mufflers dumping before the axle. the N25 (?) bumper/exhaust looks pretty cool but was not an option in 66.

    I have a header and flowmaster on my toyota truck and even tho the muffler is more for a v8 (2 1/2 in 2 chamber w a header and high flow cat), it sounds pretty good to me. My thought is if a traditonal american style exhaust system sounds and works good on my import truck would an import style muffler be the same on my domestic car?

    Almost scared to see the responses but lemme have it...

    My little brother has been telling me that I should do the same thing to my bow-tie ragtop.
    I don't know if he's serious or just kidding but I think that if it sounds silly on a 4-banger, then it would probably sound twice as funny on a big V-8! :laugh:
    Seriously though, I've heard that putting the mufflers as far back as possible may be good for performance.
    Corvettes have been that way since the '63 split window cars, except for some of the 60's-70's models that had the optional sidepipes.

    That's a very interesting idea...I'd be up to seeing and hearing what it would be like. Personally, I wasn't sure about my 3" chrome tips coming out the rear of my LeSabre were going to look good or not. I took a chance and they are awesome!! I didn't think tips designed for a big truck would look good on my Buick....

    Here's what they look like currently. The cut of the tip coincides with the curve of the bumper...pretty neat how the guy set it up. Kudo's to the Midas guy...I had to find the best Midas guy in the St. Louis area, because everyone else made it look like complete sh*t.

    Adam, the more I see your car the more it grows on me. I used to not be able to stand them, but that car is just beautiful! Just goes to show, a nice example of any car (well, almost) can be a peice of art. I'm really likin' that thing now!:TU:

    I think the biggest reason to put the muffler where it is is that there is more room under the trunk than under the seats.

    the cars are unibody meaning they can't hide the exaust between the frame rails. they put it down the center where a drive shaft would normally go.
    although yes there is a decent amount of room for us to put it behind the bumper too. it was just convienent to put it under the seats. (there is also a lil more structure there on our cars than way in the back for hangers and the v8's mufflers weigh more for the most part)

    this is just my opinion after working on both types of cars.


    also notice how high the trunks are now? wonder if they would move the muffler back under the seat they could lower the deck height. hmm....

    another idea is so that it would warm up faster and be less prone to rust. (water allowed to evaporate) newer cars benifit from better coatings on metal.

    I also own an 87 honda accord with the muffler WAYYY in the back (though now its not doing anything cause the exaust broke before the cat. sure has a lot more torque in the 3500-5000 rpm range though)


    just a few blerbs

    Chris,

    Thanks for the good words on my boat:grin:

    I am currently in the market to sell, although I would keep it for the rest of my life. I need to make room for my Centurion Convertible. I think I will try to keep the car as long as I can to drive while the Cent. is being worked on....the top is a mess, but the rest of the car is solid. If you are interested, take a look at the link in my signature...it has a bunch of info on the LeSabre I'm selling.

    I have a muffler off of a buddys integra, 2 1/2 in 3 1/2 in tip. We pulled the turbo and all the other goodies off of it so he could trade it in as stock. It was a really nicely done car, low 12s, no NOS and no wings (car looked stock except for the wheels). He never did pick up the muffler so I have this hideously expensive polished stainless thing. One of these days I will haul it out of my storage and hold it up under my car to see if the damn thing fits anywhere. If it fits I may try to find another one, if not, on Ebay with it.

    Mufflers in back

    I did something similar about 10 years ago on a '76 Jaguar XJS. It had a Ch**y smallblock 400 with rams horn manifolds. I had my hot rod muffler shop buddy run 2.1/4" stainless pipe to the back and put a pair of stainless SuperTrapp mufflers on it.

    These mufflers are kind of like a fat glasspack with the back end plugged. There are a series of diffuser disks that stack up under the back cover - each disk has a certain amount of free area to allow exhaust to escape, and you can adjust the number of disks to get the performance you want.

    This was before the rice rocket revolution, but the dual muffs looked kind of like the fart pipes you see now. Don't think I would do this kind of installation again as the mufflers do not flow as well as the current competitive units from Straightline or Flowmaster. And the tone was kind of blatty when you got on it.

    It was a very unique look for the time though - car was black on black, the stainless pipes really stood out. Some day I want to do another Jag with a 455......
