Hey Tricky!

Same deal here......K&B 13cc OB in need of a pipe. I asked a few people and got pretty much the same answer: An 11cc pipe is your best bet. mainly because nobody has done any R&D for 13cc J-pipes.

I ordered 2......an Aerotech, and an Irwin. The Aerotech has a nice alum header. but you have to cut the header to do any tuning. and the Aerotech is an open pipe( no muffler).

I waited almost 2 months for the "new design" Irwin. It has the old style copper header, but the inlet of the J-pipe fits into the header pipe and will travel about 1". So you are able to play with tuning length without cutting. The Irwin is also a Quiet Pipe........It has an effective silencer built into it.

And the big question.........Which one runs better?? Gonna have to wait 'till spring for the answer. The Irwin was a little over $100 Retail( thats for the complete set-up including mounting hardware) The Aerotech was $115..........I think that was supposed to include mounting hardware, but my supplier forgot to send it.... Anyone know how an aerotech J-pipe is intended to be mounted??

Good luck, let us know what you find out

Last time I spoke to him, Our buddy OB NUT was looking at the same problem.....

Hey foolwithtools!

thanks for the info it sounds like the Irwin pipe is the better deal, being a quiet pipe is usefull as my local pond is in a residential area, and im trying not to upset to many people! Dose the muffler affect the preformance?

I dont need a pipe just yet but excange rates are good at the moment so it makes sence to buy one soon so mabey i cant wait untill you test and compare your 2 (when is spring there) Its summer here now (New Zealand)

Anyone else have any thoughts?

Thanks Trickey (Shane)

Hey Tricky,

I'm in the Chicago area. The saying goes; "April showers bring May flowers"..........so end of April or early May is "spring " around here.

Most will tell you that a muffler will not change performance. Not having much practicle experiance, I'll have to go with what they say............. I've been asking questions of many people about tuned pipes. there are a few basic steps involved in tuning your tuned pipe................The rest involves prayer, practice, and experiance.......( maybe an investment in a voodoo doll...). I'm not sure if anyone has written the complete book on tuned pipes..........maybe I should ask more questions and start writing down the answers.

I want to know the same tings most boaters want to know...........How to tune your tuned pipe in 3 easy lessons. I'm sure all that there is to know can't be contained in 3 lessons, so my next step is to ask our Fellows what they know.

Best of luck from cold, windy, and soon to be snowy Chicago,

Bob the fool :blink:

Right now, I'm working on setting up a 13cc with either an Aerotech or Irwin J-pipes. Haven't had a chance to get the boat/motor on the water.. Too many projects at the house is keeping me inside. Now that the temp has dropped, it might be awhile before heading out.

707 is where I got the header from: 707 Give Joe a shout.. He has 11cc pipes, they might work for the 13..

Hey guys thanks for the input

As for the pipe affecting preformance i was meaning is a open pipe better preforming than a quiet pipe.

Is that Mr Irwin of Irwin pipes?

Just the man i need to talk Too!

Thanks again Trickey (Shane.)

TRICKY ,, YEP YOU GOT HIM , I WOULD APPROCH THE MIXING OF HEADERS WITH PIPES OF DIFFERANT BRANDS OF PIPES. THE LEJUNE HEADER IS SMALLER IN DIA. YOU MAY CHOCK THE 67 DOWN WITH IT , AND YET IT MAY WORK ??

I SEE SOME UP THERE DOES NOT LIKE MY COPPER HEADERS , THERE IS ONE THING THEY WILL DO FOR YOU , SAVE YOU MONEY , IN ALL THE YYRS I HAVE MADE MUFFLERS I HAVE NEVER HAD TO REPLACE A COPPER HEADER FOR ANY REASON ?? WHEN I FIRST STARTED I MADE THEM FROM ALUMINUN, STAINLESS AND THEY ALL CRACKED

Cheers and Merry Christmas Trickey.
