  1. Not at this time.
  2. Thinking of this for the next build but I'd have to get more feedback from the collective to see if it's something everyone wants.
  3. Not sure I understand your question but the system will mount right up to a stock 1750 or 2000 exhaust manifold. No grinding required.

I know it will mount to the manifold but Im not sure about the bottom contours of a '86. As far as a CAT/flow performance I'll leave that to be answered by someone from MAGNAFLOW. Hopefully they drop in on the conversation.

Hmmmmmm.......... I’m not sure about this James since the whole design was changed. I know that one of the issues with the 1600 to 1750/2000 engine was the height differences. For this reason the 1600 design was abandoned so I'll have to check to see if this would fit a car with a 1750/2000 motor but with floor pedals.

Here are a few more pictures fo the final systems on my car (red GTV) and BB member Keyspiders car. Notice the tip that he had added onto his. A very nice touch but I thought this would be best left up to the final owner to decide.

Simon,

Nice system. Here's my "what if": Will it fit a Giuia Super with floor pedals and a 2 liter motor ? If not can it be modified ?

Thanks,

Dan

I'm not sure but you are close enough that I can bring one over for you to see if it will fit or not.

It appears the tip is squared off even and not like the original GTV tip. Any thought in haven't that done?

Shouldn't be too hard to trim the tip with a decent hacksaw if you wanted to. Or to polish it (like I would do with mine).

For those dithering... again, I want to point out that this is a very reasonable price. I paid more than $600 to have my system made and that took 3 trips for re-adjustments to the muffler shop. And then I still had to get some final welding done myself to get the exhaust tip to stop thunking loudly against the body (at which point I noticed the muffler shop (bozos!) used regular welding rod instead of stainless steel stuff as they should have). Way to go Simon, for making this system, I wish it had been available and fit (I have spruel headers and floor pedals) during my restoration. Even if this system needs a little tweaking during the fitment process, it's still a great deal.
(Regarding jclarks question about grinding... he may mean that some welds leave a high ridge line instide the pipe. Performance oriented types will definitely want to grind those down if possible. But I bet the magnaflow welds on Simon's system are well done and need little like that.)

    People with EFI will want at least one...

I was referring to a possible 'ring' of built up welding material on the inside the Flange ( coressponding to the location of the weld on the outside of the Flange )...

We did think about this and also about chroming it.
It was decided that it would be best to leave the final touches up to the final owner.
As you can see from the photos the tip can easily be removed and adjusted for any modifications.

I didn't notice any but Ill take a better look and try to get some detail shots of the flange area for you.

Are these systems available for a limited time only, or will they become part of the regular Magnaflow catalog? I have a backlog of parts to buy and was hoping to delay this one for a little while.

A good quality Cat will have a minimal effect on flow and performance. At peak RPM you might expect a power loss of not more than 1 or 2%; throughout the rest of the RPM range the loss will be negligible. If you have a performance motor, you might want to upgrade to a Metallic Cat for a few more $$. Consider that a typical aftermarket Cat with ceramic "brick" will have a web thickness (wall thickness) of about 0.006" while a Metallic Cat has a (foil) wall thickness of 0.002". The thinner wall thickness offers less resistance to gas flow.

Magnaflow offers both products. See:
