Would there be enough clearance under the car to install long tube headers useing ramps or jack stands ?
Yes, Ive done about 10 sets on the floor.

You'll have an easier time with SW on the floor than Kooks.

Yes, the SW's CAN be installed on Jack Stands.
Just, be easy when you massage the Dipstick Tube!
:rolleyes:

I was just replacing a broken fenderwell liner this weekend and noticed that with the liner out there is very good access to the exhaust ports.
Have any of you guys that have installed headers removed the fenderwell liners for the instal?

It would have saved my hands from getting roughed up, yes I considered it. Did not do it. I worked off a lift and I still hated it.
Smaller hands, like Zack's, would have helped too.... no I won't be installing them myself again if I can help it.

Stainless Works headers? Do they make a Marauder-specific set of headers for our cars? How much are they, and where do you buy them?
Have you checked emission laws in your State ?
Can I remove my stock exhaust manifold/catalytic converter and replace them with a header/catalytic converter combination on my RX-7?
Not legally. As mentioned above, CARB or the EPA does not allow replacement or relocation of any of the stock catalytic converters. They require that all original catalytic converters be in their original positions, and replacement of multiple catalytic converters with a single non-exempt "high flow" performance unit is not allowed.
Although using a header (or downpipe) and catalytic converter combination might pass a tailpipe test at a California tailpipe emissions test, it would NOT pass the visual inspection portion of the test. Since the engine configuration of the rotary engine in the RX-7 is rather unique, it is possible that some test station technicians may not be familiar with the this layout, and they may not even notice that a header (or downpipe) and/or replacement catalytic converter has been installed.
California kinda weird about emissions.

When I put in my Kook's Headers I pulled the front wheels and used about four 3/8" ratchet extensions, a universal joint, and a deep socket to put on some of the nuts.
I didn't pull the fender liner, I just worked around the suspension opening.
Even so....there was a whole LOTTA cussin' and bleedin'...:mad:
Stainless Works headers are hands down the best designed and easiest to install.

I was never thrilled with the 45 degree dump angle on my Kook's passenger's side collector....
Why didn't they drop it down all the way and turn it 90 degrees like the driver's side collector? :dunno:

The system that includes the cats, Does that bolt up to our stock system, or do I need to purchase the cat-back system along with it? Im liking the price of the system. I may have to enlist my pal Krytin to come to my shop for a install meet.

Works for me Paul!
We'll practice on yours and perfect it on mine!!!! LOL

Hey, if three's not a crowd, I'd love to see 'em being put on and heard the sound of it all after its done, might even convince me to get my own sooner

Yes, the only issue is that the 2.5" out of the "cat", is bolting up to the
2-1/4" on the factory "H" pipe, it will still work, just a little flow hinderence.

Most "technicians" won't notice it. As long as there is a converter or converters you'll pass. Here in North Carolina they check for any codes and do a visual inspection. I replaced the original 4 cats with 2 cats and it pases every time. Usually the "technicians" want to talk more about the Marauder than inspect it.

Wow Im fighting to keep myself from grabbing my credit card.

I agree. If one decides to keep the EGR, then they'll probably have to extend the tube (the case for my car).

I was told that there are fitment issues with their full system (IIRC, the problems were over-the-axle clearances and tailpipe alignment).
Concerning fitment, fabrication will be required to get the headers or cat'ed setup to align properly with the stock exhaust, as was the case for my car after header installation. Concerning Stainless Works' cat'ed setup, the headers are long (obviously) and the pipes they show in the picture (here (http://www.stainlessworks.net/cart/images/MAUCAT.jpg)) look like they add over two feet. Depending on the actual added length, you may require a sharp bend to adapt and reach the H-pipe. I'd recommend having the exhaust shop use mandrel bent elbows (or better yet, find a shop with a mandrel bender). Otherwise, if they're going to compression bend, I'd go slightly oversized. Also, concerning diameter adapting, any decent shop should be able to make you a reducer, or you can order them for a couple dollars from Summit Racing.

Did anyone have any issues with the steering shaft? You can see what my issue is...

And a few more... RED, as you stated, the EGR connection was not oriented properly and took a lot of work to modify for correct fitment. :confused:

Yep, Sherman had to grind his steering shaft to resolve his problem. You can also shim the motor mounts with spacers.
No 2 sets of headers are alike.
I had no issues when we put them on Killjoy's car.

Yeah, I figured as much... No two cars are alike either... Welcome to the world of custom modifications right? ;)
I plan to just grind a little off of the shaft and move on. I thought I would share with you guys anyways... I am really happy with the way that they sound and perform though. Mark, I think you will like the way that my system turned out. It sounds almost as fast as your car now... :D

My egr fit fine but I had to grind a bit on my steering shaft to make it not rub. Still was very happy with the headers other wise.

No. No problem.

Yes, as others mentioned, you can simply add spacers to the engine mount bolts. Fixed my problem. I agree with Zack that no two headers are the same.
