Engine/Transmission (1994 - 1998) Exhaust question

[farkum]

I am getting ready to start building my own exhaust for my truck. I have a 4" bullydog downpipe to get me started and then I was going to do straight four inch and have it exit out the side in front of the right rear tire. As far as I can tell this will eliminate the loop up and over the axle making it easier to design and actually more efficient. I was wondering if anyone has pictures of exhaust like this? Also, any reasons not to run it this way? I do work at a detail shop so my truck gets washed about three times a week, not too concerned about the truck turning black.

Hey farkum that's what I did on my 96. I think it looks good (sorry I don't have a digi cam so no pics). I did it for ease of redoing my exhaust, more efficiency, and cool looks--I put a 5 inch tip from stainless stock and cut a 45 degree slant on it. I have had exhaust shops tell me that the 90 degree bend hurts efficiency, but have had others tell me that it does't matter that much, and the 4 inch and shorter exhaust pipe is better. The one thing you will notice for sure is that you have to clean the chrome hub caps a lot more often! Good luck, and post pictures.

I finished most of mine last night and the rest a couple minutes ago. I went straight 4" back then a 45 degree down and 60 degree over. This way there are no 90 degree bends (although I wasnt concerned) but more importantly I wanted the tip coming out at a slight angle because I thought it looked better. I will get some pictures up as soon as it stops raining.

Oh yeah, it looks sweet and sounds even better. Definately dropped my average MPG around town significantly because I cant keep my foot off the skinny pedel.

Must be nice, down here it is against the law for a vehicle to have the exhaust dump before the rear axle. . So i am going 5" out the rear no muffler. .

That's weird.



In Maine, which seems to be pretty strict about vehicle inspections. (No cracked windshields, no lifts, no over stock sized tires on ABS rigs, etc)... the exhaust needs to go past the passenger compartment... ie... the cab.



How about the mid 90s Ford trucks? My Mom had a 97 and the pipe came out in front of the back tire. Not legal in Georgia? :-laf

 

[WadePatton]

Yeah, is that a local thing or state of GA?



Like he said, ford had some stock gassers coming out before the axle. And how about stacks? What about the "lake pipes" of the 60's? Sidepipes that is.

They tell me (muff shops) that my stacks are too tall for TN, but TN never has said anything about it.

Yea I remember those Fords and there was a thing here about that... The law states that the exhaust must exit past the rear axle of the vehicle on passenger vehicles. .



But they will let you drive in a car that has been wrecked 15 times and parts are falling off of it

There is no law in georgia about the exhaust exiting behind the rear axel. The law states it must exit from under the chassis. We have and still get buses with side exhaust, even the viper comes that way. I think the talk about the law in georgia was the old timers myth. I have asked the DOT and they comfirmed that the law was never a real law. Just a myth.



Think about it if that was a law Tractors and trailers would have to remove there stacks and run exhaust under the chassis.

The factory TA challengers would have been outlawed in the south for side exit pipes in the 70's.

 

[Boosted6]

The law pertains to passenger vehicles. . Call your ex brother n law and ask him. . He is a po-po...

 

[JWaters]

the viper is not a bus neither is the ford trucks, that law is a myth... . miss read by all the old timers.



Joey didnt know the correct answer but the DOT is the Department of motor veh. They know all laws including the one for window tint...



Did you get your truck yet?

Never heard anything else back... And he is closed until Monday... .
