Got pipes?

Tim,
Modifications look great! Can't wait to hear that thing. Very nice work.

Thanks again guys. I thought you might enjoy that, John. Only having driven it so far (and not having heard it from shore), Id say the sound is comparable to a '70 Mustang with a Holman Moody 302 that used to be on our lake. Others have told me its considerably louder.

I got the opportunity to drive Keith's new '94 last week (sweet ride, by the way!) and I had almost forgotten what my exhaust used to sound like- it certainly doesnt sound like that anymore!

besides sounding louder is there any other advantage from going to single to dual outlets?

Does one need another reason beyond louder and looking cool?

Don't think so.

TRBenj, you wouldn't happen to still have your invertraflow? I would be very interested in purchasing it if you were keen to part with it?

Tim, There's a guy on the2001 looking for one too. I did give him the link to this thread.

Too bad those tips werent available 4 months ago, they would have made life a little simpler for me.

Youre correct, I believe the stock exhaust size is 3" on the 2001. You dont need to remove the gas tank to replace the tips, though it would make it a lot easier to have it out when it comes time to install the new hardware.

Theres no way you'll fit a 3.5" tip into a 3" hose- they dont stretch at all. Id say your best bet is to find some tips that are 3". I only went bigger since I already had one 4" hole. That would save you from drilling new holes, and you can reuse all your hoses. If Eddie Marine doesnt carry 3" stuff, there are other places that do.

I really don't think rubber hose all the way out is much louder than the stock "mufflers". The copper and SS pipes make noise!

Tim, if you're comparing your boat with the dual SS pipe + hose to a stock boat with all hose that is not even close.

I am talking about 3" hose from transom to cast iron manifold not being much louder than with the stock through mufflers.

On the '80...it is rubber hose all the way to the back....and it is loud.

On my '81 my brother had a guy at work make him copper tubes. Now that boat just sang. The copper gave it a much different sound. I still have the copper tubes up in my attic if I ever find the time to add them on to my boat.

John, yes, that must have had a deeper, throaty sound I'd imagine. Copper, huh, they must be worth a pretty penny.

By the way, John, my Nautique is finally running smooth and strong. It's well broken in now. Hopefully can get you out in your old boat again someday. Still looks like a million bucks. Your buddy took great care of it!!!

Paul, I have the original 2&1/2" copper on my 312. All I can say (because I've never had all rubber) is it sounds normal for a 60's V8. No where near the sound of a Holman Moody - Just pretty mellow. Hopefully, the stainless pipe you have is one of the thinner tubings and not pipe (scd. 40). I wouldn't go putting a heavy wall pipe in your boat!

Pete,

Haven't put the stainless in yet......just wanted to know opinions.....(especially yours)about what it would do for the boat. if i do put in stainless it would be thin wall.

See ya in a couple of weeks or so....

Paul,

Nope, no video or sound clips yet. Maybe one of these days.

It shouldnt be very difficult to do- just remove the muffler and add a Y pipe and some reducers (3" or 3.5" in, 4" out) and run the extra hose.

Heres one example of a 4" in/out SS Y-pipe: http://www.mandrelbendingsolutions.com/servlet/Detail?no=446
