How can I make these pipes quieter, they are way too loud? Looked inside and there are baffles.

If there are already baffles then what can be done has already been done. A nice quite pack system (merged) will quiet it down AND enhance performance.
By Brad H 1498 Date 2010-08-26 04:34
Yep, those things are RUDE and they only get louder with age. They look older so chances are the fiberglass wrap on the baffles is gone. A header and muffler are the only other choice. The exhaust you have is the most quiet of the dual cannon style they only get louder. A 1 5/8 racing merged exhaust and a single muffler will make it drivable and like Jeffery said ADD HORSEPOWER and torque.

Just use the ones with removable baffles, that way if your neighbor pissis you off you can take out the baffles. LOL            Ken ( Billy Bob ) Lee.........................

motorcylcle inserts will fit inside those, u may have to gut the megaphone to get them in but baffles out of a goldwing or harley will fit and there for about the same size engines

You could cut them off at the collector and install a muffler, traditional or Borla/Supertrap or motorcycle.

By Dave Lockley Date 2010-08-26 21:34
Thanks for the input. After looking at the pipes I may want new one, how about the sound from these? Dave

By Allison Daytona Ken Date 2010-08-26 22:21
I have had a few pairs of them, I like them , they have a low deep sound,     Ken.........
By Dave Lockley Date 2010-08-26 22:42
Thanks Ken, I think I'll get a pair coming and some black heat paint. Great info here guys, I thank you very much. Dave
By Jeffrey P 655 Date 2010-08-27 00:29
Dave...just another opinion....

I don't like those at all. Poor performance, still kinda loud.

Something like this is much better:

There is nothing wrong with those pipes, they were probably some of the first designed for buggys, there was nothing wrong with them then and nothing wrong with them now, they are a good price, give you just enough sound and you are probably not running a souped up motor anyway, I have both kinds and you will be fine, plus everybody can get on my tail if you want , they look good, I think the muffler stuck up in front of the motor looks stupid myself, but then again I just got home from BIKE NIGHT so hate me if you want to LOL !!!!
By Dave Lockley Date 2010-08-27 02:48
Well this motor is built a bit but I do not know how much. The thing sounds like it has a bit of a cam to it. It has two Solex carbs that are running too rich and the power is great. I just need to have less noise at speed and still have a little style on the buggy. This is not to be a show buggy just one that I like and drive most days. Dave KI4UBK

I just put a pair of those on my friends buggy with my old 1776 in it. They are a bit loud, but not horrible. People will definitely know you are coming. They aren't that bad when cruising if you are in the car LOL

By Allison Daytona Ken Date 2010-08-27 14:14
Dave they have a built in glass pack instead of a metal or a wraped metal baffle, so to me thay are not as loud as the ones with baffles, just imagine a cherry bomb muffler but not having a V8 going through it LOL, I am not complainig on what the others say by any means, If you want quiet they hit the nail on tha head, I personaly like the dual exaust even though it may not preform as well as the muffler system on a high output motor, Here is a picture of the Allison with the sroker motor with the pipe minus the muffler and here is a picture of my other Allison with the chrome duals that are like the black ones but chrome instead.     Ken...............

By Brad H 1498 Date 2010-08-27 16:27
That merged on Ken's without the muffler will make your brain itch LOL. I had a similar one with a "baffled" pipe called a Bobcat exhaust. I drove it on my last buggy for about 20 minutes then took it to the shop and made a pipe and cut off one of the glasspacks that you are getting from an old system I had and welded that on instead. MUCH better. The dual cannons seem to fill out the back of the car better and give it the correct "look" but for all out performance I use merged headers and a muffler. It's all a matter of personal choice, it's your car do what you want. There is no right or wrong.....well there is, but some people just have bad taste LOL

By Allison Daytona Ken Date 2010-08-27 16:49
WHAT DID YOU SAY BRAD, I cant hear you I been driving the blue Allison LOL
By Dave Lockley Date 2010-08-27 19:11
Seats came in so we have a good start on them and pipes, brakes, and other parts will get here soon. Dave

By Allison Daytona Ken Date 2010-08-27 20:18
Seats look nice I like the bolt in rear, its a lot less work than building the rear from scratch what type are they ?
By Dave Lockley Date 2010-08-27 20:28
Now don't laugh, they are Jeep seats from JC Whitney.
By Allison Daytona Ken Date 2010-08-27 21:14
Not me I wouldnt ever do that, I like them , I never thought of that , I was tryig to come up with a low price fix on some of these buggys I buy and sell, we have a salvage yard where you pull your own parts and it may be a good way for me not to put to much in the interior, Thanks        Ken......................

Hey guys, the Clipper want's to hop up and down in rev, is this clutch, trans mount, other? Dave
By Brad H 1498 Date 2010-09-07 02:51
Check your rear shocks and your tranny mounts. An easy test of shocks is to bounce the car a few times and then let it settle if it bounces more than 2-3 times after you stop pushing it they're worn out. Pry between the bellhousing and rear mount cradle,  more than a little bit of movement means the mounts are busted. Try prying the nose of the tranny side to side and up and down, again any excessive movement means a busted front mount. The clutch will not cause the car to hop, it will chatter, slip or not disengage

By Dave Lockley Date 2010-09-07 22:18
Thanks Brad, I think it is the trans mount. I'm looking at new trans mounts but I need to look at what they should look like. I'll find some pics online.
      This seems to be a good buggy but there are parts to look over and rebuild. Some people can drive anything and it will work fine for them, for me it needs to be done the correct way or I'll be working when I do not want to. Dave
By Dave Lockley Date 2010-10-09 15:57
I removed the baffles from the old pipes and replaced the fiberglass. This was only a little quieter but it did help. The metal is in good shape but the glass only had a small piece left in each pipe. Dave

Dave, what type of track did you use for your front seats?
By Dave Lockley Date 2010-10-09 23:16
They are on the VW tracks, just added tabs made of 1" X 3/16" flatbar to the bottom of the seats. I would get you a pic but they are a pain to get on the tracks. Dave
