Any way you do it, it's going to look like hell. This would probably look better:

 

a better question is why the hell?

unless you are running an irs rear in your fox, put them over the axle, if you are running a cobra irs.. then get a cobra catback.. problem solved

 

Foxes with an irs are the only ones I've seen also.

What's your reason for wanting to do this ?

 

I'm sure if anyone did, they would scrape the road on any bump you would hit.

 

I'm running dumps, no interference.

 

I just had it done last week some info as to why . When I had an x pipe with dumps done it looked like cr@p and it did hit on the x pipe over speed bumps and when they did road work around here the one muffler was knocked off so I had the exhaust redone and the reason I went under is I have a true coilover suspension with an anti roll bar and 3" pipes and there was no room to go over . I have the fuel cell out redoing the fuel system right now so I will try to get some pics to post tomorrow and will start a thread when I go back to the muffler shop to get some better pics and will post detailed pics in a couple of weeks .

 

i love internet geniuses! ! ! !

explain how running tail pipes under the axle would hit on every bump?

Bdubya...do you have a problem with the center section bottoming out on every bump? cause thats 3" lower than the axle tubes!

ford ran then low and never had a problem on IRS cars.

347 lx.... maybe because its easier to remove the axles at the track? HMM, HMM, HMM???? less weight? cleaner install? OR maybe just maybe coilovers and a ARB are in the way?

those ####ers are gonna rub everything! god. i hate people who talk out of their azzes

 

Seeing that your pics are of a car on a trailer with slicks i figure it is mostly a track car, but a street car ( in some states) would have problems with that setup. I had a classic designs side exhaust in a 91 and the mufflers hung down about like yours are and they hit every speed bump i crossed. The problem is not with the pipes that run under the axle, its the way the mufflers have to be possitioned to run the pipes under the axle. Like i said im sure it depends on where you are and how bad your roads are. As far as factory irs cars the pumpkin is higher up in the car and does not move.

 

Doesnt flowmasters 3" tailpipe kit run under the rear axle? I might be confused and thinking of something else.

 

Thanks guys for the responses and pics. The reason I wanted to do it is because my exhaust is set up where I can unbolt each part quickly and when I've had it over the axle before it was all I could do to get the pipes off on a rack, much less the ground or a jack. I like my car to be quieter for daily use with the option of running dumps or even just x-pipe or headers for certain cruise-ins etc. and the main plus is being able to remove to work on other things or clean/recoat etc. I had seen it done in a couple of magazine articles done in a really clean looking way and my header,x-pipe, and bullets setup is sometimes a little overwhelming when cruising for long periods.

 

Here are some pics I took today you get the idea there is plenty of clearance 3" exhaust front to back with dynomax 409 stainless ultra flows .
The only bad part is I have to jack the car up from the rear and put stands under if I need to work under the car instead of just jacking from the side but if I need the exhaust out of the way 10 bolts and the hole exhaust drops and can be moved . In a couple of weeks I will add a link in place of the pics when I start a new thread for those interested in looking .

 

Looks good.

 

Visit www.performanceautosport.com and look under "customer's cars"... There is a 1993 Cobra R on there with the best side exhaust setup I've ever seen...

I'm planning on running a side exit system for make more room for a torque arm/ panhard bar...

Another option is to route the pipe thru the body of the car and out the side behind the doors... But that's a bigger pain in the ass

7 pages of cars and I did not one of a 93 Cobra R

 

So basically with your pipes running under the axle you can never hang your axle at full droop...

 

I can see how the exhaust routed like that would work on a drag car only, but not on a true daily driven street car. Driving in areas, such as southern missouri where the roads are loaded with sharp curves, dips, and steep hills, the exhaust would simply be ripped right off of the car on the first hill you pop over due to your suspension going to full travel.

When the exhaust is only mounted an inch or so from the bottom of the rearend in those pictures, then you are asking for trouble on the street. A good pothole would ruin the exhaust, as a result of longer travel in the rearend forcing the exhaust down. A nasty set of train tracks, even an extremely hard stop will cause the nose to dive and the rearend of the car to lift, resulting in an extended rearend which would in turn rip the exhaust off of the car.

I have no doubt that on a dyno, you would make more power with the same exhaust routed under and STRAIGHT, than with the sharp curves put in the exhaust going over the rear axle; however I just don't see it being practical on any car other than a trailer queen.

Contact Justin Burcham on StangCrazy.com . I believe that his old F/S Racecar had an under axle setup for the exhaust before the rules were changed.

 

im running a full custom single 3" to a dumped magnaflow but planning on going under the rear and cap it all off. my reasons are my exhaust isnt in the stock 5.0 location and i dont feel like bending the pipes around the suspension stuff so its not that crazy of an idea.

my buddy has a GT that has a blown 331 and he runs a straight shot out the back under the rearend so i have seen it b4 also.

 

Under axle tailpipes is popular on 4th gen fbodies. You could check those out for some ideas.

 

Florida is also flat If that car was driven around here, you would get full suspension travel popping over many of the hills on the back roads around here, scenic routes and what not, and it would rip that exhaust right off the car, as the rearend travels a lot further than 2.5" You can easily go airborn at speeds less than 45 mph on a lot of roads down here, the apex at the top of the hills are that extreme.

My point was, having exhaust like that, isnt as streetable as the stock design. Granted it will obviously work in areas where you don't run into roads like that, however in states that are hilly/mountain states, it would be an expensive lesson learned that it isnt a very good way to go. Im glad it works for you, just remember what I said about taking a hill too fast I am truely impressed with how well it looks under your car. thumbs up!

Thank you .

 

Bah, that's nothing. You should see Darius Rudis's side setup.

 

or go deaf by listening to it!

 

in those pics hes more likely to rip the coilovers off before he loses the exhaust. doubt either will happen but wow that looks really really nice

 

IF youre talking about hitting something while driving over it.

what is being questioned is if he was in full axle droop (suspension in full extension) it would be hanging on the exhaust. I can tell you with certainty that if that were on my car it would be ripped off. 2.5" travel is just not enough. id love to be able to though

now if his shocks have a limit of less than 2.5" extension then he should be OK.
