The Stovebolt Site Forums The Shop Area The HiPo Shop Dual exhaust system question?????

I am building a dual exhaust system for my 235 starting with Fenton cast iron manifolds. I would like to put a crossover in it before the mufflers, but I am afraid that it might kill the distinctive sound that an inline 6 with dual exhaust makes. Has anyone done this and if so did it affect the sound? Thanks, Diceman

I have not used a crossover tube downstream but have heard ones with duals where they just added a second exhaust flange/pipe and did not weld in a divider plate between the front and back outlets. I guess it made them breathe a bit better but they did NOT have the split sound.

an X-pipe or H-pipe would help a bit on breathing, however you will loose the split manifold sound.

I have the exact set up you are looking at on Walter. The Fenton headers with duals, glass packs and a cross over pipe. I had it installed first without the cross over and then went back and had it added. I actually like the sound better with the cross over... my 2 cents worth.

I just installed Fentons on my '55 1st 235. I bought Patrick's all stainless steel exhaust system, and mated it up to the Fenton's. The stainless muffler is 2 in, 2 out, and the pipes come out of the driver's side rear shotgun style. The sound is incredible, and I definitely picked up some HP as the improvement in acceleration is noticeable. I hate exhaust work, but Patrick's set up is a snap. No more exhaust fumes in the cab...yippee!

Arpee, I just read your story about Walter in the gallery. Very cool! Thanks for the info.

Diceman,

Patrick's dual-exhaust system is everything that Jivermo describes. It is a beautiful system, all parts fit perfectly, all parts are stainless steel, and the sound it probably what you want (it's a little too loud for my tastes but I am getting over it). It is an expensiveness system but you truly do get what you paid for.

Jivermo, I wish I had posted this question about a month ago. I have never heard of Patrick's exhaust system before. I did a search and found some pictures that 49geezer posted showing his Patrick's install. It looks almost exactly like what I am building. Is the muffler straight through or is it chambered? My search never did reveal where to get one, although it is to late now anyway. I have bought all the materials and have already built my head pipes.

Wow-that's a good question about the muffler. I seem to recall that it was straight through, with a baffle system surrounding the passageway. I know that he also sells the muffler separately. Why not give them a call out there-number is 520-836-1117, and talk with Patrick or his wife Danese. They are really neat folks, and have been very helpful to me with info. I think that they have some of the best pricing on their product line; you really do get what you pay for with a lot of restoration supplies. All the best...
