Ehaust Question/help...

Dose it matter that mufflers are staggard like in my picture? Unfortunately, this configuration was my best option, the muffler would not fit under the cross member on the drivers side due to the master cylinders' location.







Also, I used 2 1/2 " tube from the engine to the inlet on the mufflers, but I would like to exit the mufflers via a reducer using 2" tubing. Does any one know if this will be a problem?

 

exhaust question...it's late.

 

Why wouldnt you put both mufflers in-board.

 

I could still do that. put both mufflers in board.

 

what car? porters rule

 

in the third pic, what about 45 degree the pipe through the frame, the line up the mufflers at the same place. then go from there... my thoughts what i would do.

 

Mount the mufflers where ever they will fit and look symetrical and then run the tubing to them. Sorry but your design looks like shit. I know you can do better and so do you. That's why you asked. I've done hundreds and most all are different in some ways.

 

Yes, I agree, both inboard. Otherwise run a crossover tube, it will help equalize the exhaust sound. It will sound different from side to side depending on where you put the mufflers, may not be that noticeable since you have large pipe and mufflers that don't muffle too much.

 

I think inboard would be the best location and fit your pipes to them.

 

Just curious, on his original question of performance.....Anybody know??
Cheers..........

 

I agree, inboard is were the passengerside muffler will go using a couple of 45 degree bends as suggested by. FlatFlathead31coupe.

 

Is your driver-side pipe resting on the tranny?

 

No, it just looks that way from the pictures.

 

I reworked the passenger side exhaust, moving the muffler inboard and even with the drivers' side muffler. I am much happier with the muffler placement...

 

I worked my rear end off getting my exhaust system straight and perfect. Then I took my car off the jacks and never looked at it again...

 

That looks a LOT better!

 

@Pitts64: I will most likely do the same thing, but if I would've left the exhaust the way it was, it would have bothered me and I would've ended up redoing it. So, better to fix it up now with the body off, than have to do it later.

@Tagman: Thanks.

 

I just don't like the left pipe that close to the transmission......

 

Good point. I had the same problem - not enough room under an early Ford. I bought some DEI insulating wrap and used it to wrap the exhaust at the trans and it seems to be doing a fine job.

 

Probably not enough difference to measure, two considerations:

1. The further back the mufflers are, the less the volume of exhaust has to flow through them, due to a very slight cooling of the exhaust the further it travels through the pipe.

2. On the flip side is that that slightly cooler volume of exhaust is also more dense, so likely doesn't flow through the muffler quite as easily.

So there are very slight changes in the physical properties of the exhaust gasses as they get further away from the engine, and I'm not a rocket scientist, so have no way of knowing how these changes might affect performance. Bottom line, I just wasted a bit of my time and yours pointing out some goofy trivial stuff......

 

Pitts64 is right---if I rush thru something, I usually do it over right unless it won't be seen and then I still know about it and it keeps coming back------------

 

I plan on wrapping that part of my exhaust. With the combination of the shift linkage and the size of the trany...space was at a premium.

That's funny. I've talked to a couple of exhuast/muffler shops here in town and they don't seem to think that if will make a difference.

 

Didn't waste my time at all..I appreciate the answer.
Cheers.....

 

I really like what you did on round two. It looks really good now.

 

Thanks. Iam much happier with the exhaust too.
