Also you can show them how you want them run. I don't know about in FL but here they'll let me in the shop when they have it on the lift to show how I want the pipes routed. Good luck.

Chances are,whoever you sell it to will want different pipes/mufflers/sound/looks anyway,so save yourself the money and hassle,just give it a standard fresh exhaust system and let the buyer spend HIS money to make it "better".
Just my opinion.

You wont get the extra $100 or so you stick into it. | | | | | Joined: Jun 2004 Posts: 8,597 Riding in the Passing Lane | | Riding in the Passing Lane Joined: Jun 2004 Posts: 8,597 | I agree. Go to a muffler shop & let them build a system. Unless you are going raceing 2-2 1/4" pipes would be large enough, sound better & be a neater installation. I like long glasspacks.
They say money can't buy happiness. It can buy old Chevy trucks though.

I also have a '59 Apache with a 350 engine. I 'tuned' the pipes to a specific RPM level (3500 RPM) by using the diameter of the pipes to build a reverse sound wave to 'extract' exhaust at a given RPM for a given displacement. I use the formula:
1" of diameter per cubic inch of displacement for 7000 RPM for the whole engine. I use my engine at 3500 RPM max, therefore I only need half the calculated value at 7000 RPM. Therefore, I wouldn't go over 2" diameter pipes if I were you.
