Show Me Your Magnaflow or Flowmaster, Looking for alternative to Supertrapp on Kerry Hunter Options

[hydroliftin]

I am planning to replace the Supertrapp on my 4-cylinder Kerry Hunter header with a small Magnaflow or Flowmaster muffler. If you have a similar setup, please post photos of what it looks like installed, or what the uninstalled piece looks like after the flange connector. Also, if you know the size/model of the muffler that would be extra helpful.

Thanks,

I have a magnaflow, 2 in/2 out.
I don't know if it helps, cause I have a v8.
Pretty quiet, but not sure on a 4.

with the lower cover, the muffler is hidden.

This isn't a Kerry Hunter header, but it's a similar situation. I used a Hooker system from Summit. I recommend looking on there because you can narrow down the list by shape (round or oval), number of inlets, number of outlets, etc.

This is a 3" system, but it's on a turbo 1.7, so I just wanted BIG. Haven't run it yet, so I can't say anything about the sound.

Chris -- Thanks for sharing. Your set up looks well engineered. I have a mechanic working on sorting out power & drivability issues on my 2 liter 4-cyl. The Kerry Hunter header works well, but he believes there is more power to be had by getting rid of the Supertrapp. On the dyno it gained 7 HP at the wheels just by removing the disks and running the Supertrapp fully open.

Mark -- With the turbo this should be very quiet. Thanks for sharing. Also thanks for the tip on Summit. I guess they are not just for muscle cars after all.

Here are the shots, I will have to dig for the part # of this Magna Flow. You see it fits great. WAYYY better than the Super Trap/Phase 9 Silencer that was there before. Tolle Fab in Sac is the place. Mike is a PRO Race Car builder/Fabricator. Its the real deal.

I designed the system, including the hanger, routing and exit to include sizes. Mike made it a happen. Wanted a port hole, but not the tiny little pipe exit. Not straight either. The down angle looks right, this system sounds fantastic. I suppose the best description is that it does not sound like a Type 4 Volkswagen engine. I'll get the part number of the muffler later if you want it. Give me a call later in the day, I am working on the race car at the moment...

(IMG:style_emoticons/default/drooley.gif) that looks dope Stig, what header does it go to?

Thanks for the compliment...Header is OLD SCHOOL. Garrettson Racing Enterprises. This car was maintained for many years by Dwight Mitchell. He put it all together, for a Dentist in the Sacramento area. Early eighties I am guessing. Garrettson made several tuning parts for the 914. It has a few cracks on the stub pipe flanges, but it has held up well considering it age and use. I also include here my notes before fabrication. The only real change to the notes is which tube was inlet/outlet. actual system is opposite of planned. Just made for better routing. Also the muffler does not lay back at 45 degrees as shown. Not required. Muffler was very small, so the fit was good. I had the template for the hangar, but I tossed it. Easy to duplicate. Used a 2.0 upper ears to start out, then adjusted to offset the muffler to the right to allow for the connections. Muffler is actually spot welded to the hanger. It can be removed if need be to replace. etc.

Are the K/H headers still made?

[hydroliftin]

Thanks STIG! Your solution is elegant. I have seen other solutions to replacing the Supertrapp, but this is the first one I would use on my car. Well done.

No, but you can find used ones on e-bay or here from time to time.

No problem, if you want to see it for real, let me know. When I designed it, it had to be right. Cheap/Easy is usually not right, but this wasn't to bad compared to many of the systems out there, and if I needed heat, it would be a totally different deal.

Magnaflow!Sounds awesome.

My two in two out.Apologies for the crap picture.

I'm running a Kerry Hunter with a flowmaster. It was a 3 chamber mounted sideways exiting on the right. I cut out one chamber, shortened it by 6", and squeezed it straight out the back. It sounds really good and deep. It was a handful trying to weld the body of the muffler.
