	THROW OUT your manifolds, risers, and elbows! A Better Exhaust Solution. Two winters ago (2009-2010) I resolved to replace the original manifolds and risers (riser age unknown) out of preventive maintenance with OEM Crusader parts. I had the marina I winter at perform the service and all seemed well over the 2010 season. As a 2010-2011 winter project, I decided to rebuild both engines in-frame. Upon disassembly, I observed both brand new outside manifolds and risers had failed at the block off plates leaking seawater back into the heads and seizing rings/ rusting cylinders. Disgusted, I searched for another solution to the seemingly stupid manifold riser setup that is prone to failure I found it. There is a company in Australia that custom makes Stainless Steel (not aluminum like many local manufacturers) one piece header design. They do not handle antifreeze, just seawater out from your cooler eliminating the block off plate setup. Change the zincs inside them regularly, and they will last forever. The performance gain is also notable, as they are significantly less restrictive than the stock exhaust. They are also incredibly lighter. My stock manifold elbow setup weighed in at over 100 lbs each easily. These weigh in at 14 lbs apiece! A significant weight savings. Below is the link to the manufacturer. Ask for Alan. He has a remarkably fast turnaround time given he is half a world away. http://www.hitekmarine.com.au/ Cheers, Glenn

	I purchased a pair of your stainless exhaust manifolds for my 4.3 litre Volvo back in about July 2003 engine hours 270, 5- 6 years service on the original cast iron manifolds The engine has now done 720 hours and the manifolds exceeding the life of the originals by currently two years and 180 engine hours I have had to remove the recently due to head failure and after visually inspecting them they appear to be in extremely good condition some staining and discolouration only where you can see inside the water jacket, the gasket faces have some pitting and I am considering getting them re faced I am very pleased with the product and intend to reinstall them on a new motor

	Hi Allen just had a great day driving the boat plenty of performance as we know but mate a real class product and straight bolt on no modifying that makes a man happy CHEERS!!!

Hi Kevin, just thought I would let you know that I am very pleased with the stainless manifolds. They are all fitted and the engine is going very nicely. Lots more water and exhaust flow. Had a small problem with the engine idle which increased by 400 rpm, so had to rectify that (shows the lack of back pressure) but gave it an hours run in the harbour last thursday and was very surprised with the performance, they sure are extractors.

	Final got the ski boat motor on the dyno 350 chev made 419 horsepower 390 foot pounds of torque at 5800 rpm. The exhaust worked great I would recommend your headers to anyone Thanks again

Hi Alan, The Exhausts are all in and tested now took some modifications to the decking to get the additional three inches in height clearance. I went from a three inch riser extension to a six inch riser extension for these. They are fantastic as you promised and have exceeded my expectations. I have written up the whole experience on the Bayliner Owners club and given them a great wrap. Here is the link if you are interested. http://baylinerownersclub.org/forum/showthread.php?p=505774#post505774

Hi Carolyn & Allen, I received the shipment today. I just wanted to thank you both from the bottom of my heart. You have made my best friend extremely happy. He is so pleased and impressed by your manifolds & risers. They are beautiful! Once he has paraded them around to show all his fellow boaters & installs them, I will be sure to take pictures and send them to you. I hope once our friends see them, I will be contacting you to order more. Again, thank you so much! It has been a great pleasure doing business with you.

Thanks for sending the bolts i am very pleased with the maniflods test ran today runs 20percent cooler than the older cast iron manifolds. Just one question the exhaust flanges get very hot is it normal for the powdercoating to start to bubble and flake off around all the flanges thought i had a fire but turned out to be boiling the paint off would like to hear back for peace of mind thanks to geat product quick service will be pushing your product to others AllanWilson.

Jean & Bruce Stippich - 23 May 2006

Just to let you know, I got the manifolds today (22 May 06) and they look great. I wish I would of had you send me about 50 of your brochures with the manifolds. I would like to pass your product around for people to see. I'm sure I can get some more people interested in your stainlees steel manifolds. I know alot of boat owners and most of them run twin motors. If you can send some i'll see what I can do for you. Thanks, its been a pleasure.

	Just finished with the 302 Ford rebuild project in my little Donzi. . The manifolds look and fit great. A liitle tough getting them on with the lack of operating room in my boat, but am very pleased. Thanks again for the great service and product.

	K.H. Targett Launceston, Tasmania Australia
	"...the reason for my purchase was that I wished to get away from having to use either cast iron or alloy because of their inherent problems of fatigue cracking, particularly in winter lay-ups... I am very pleased with the results".

	Mr. A.J. Spiteri Morley W.A Australia
	" I thought I would let you know how pleased I am at the outcome of my purchase. My vessel now operates approx 20 degrees cooler, it has increased its R.P.M by 450 to 500, its top speed has increased by approx 4 knots and I am using considerably less fuel...".

	" We’re getting about 55 MPH out of a 24ft ’74 Ray Flybridge! It’s a sight on the lake! We would recommend your pipes to anyone. We’ve never seen another set on another boat and that’s our edge. We are interested in selling/installing them…".

	"Hi Allen, just a quick update regarding manifolds and my mariah z255, magnum 454 power, mate this beast is now running so sweet, I am so impressed with the results: motor is smoother, sounds much sweeter, runs cooler, and cruise rpm to maintain best fuel economy has fallen by 300 rpm as power is up! A very happy customer, well done mate…".
