There is a huge difference between shorties and LTs.
Primary pipe length affects more than you might think.
More torque, power, flatter power band, more engine cooling, and more mpg.
Pictures of long tubes installed?

That's something that would be worth calling BBK tech support about. I believe that the only difference is that they set headers out a little bit to clear the fork, not physically move the collection point down on the SN. I'm not sure your assertion that there will be more ground clearance is correct.
Kurt
Yeah, I see what you mean. That's why I wanted the pictures. I've done everything to try to discern the difference but call them and ask.
I had 1-3/4" Ceramic Long Tubes from MAC with 3" Collector and I had more clearance than that. I could go over speed bumps lowered with no problem. Never dinged up the exhaust on anything.

The previous posters will have to give more info, but I know that your transmission configuration plays a big role in the answer to your question.
I talked to BBK about this. They make one set of headers in 1 and 3/4" that fits both the Fox and the SN. However, it does not have a provision for the EGR. I can't remember the part number off the top of my head, and it doesn't specifically say SN on their website. Give them a call, and they will tell you.

I would check out what Kurt mentioned concerning the BBK 1¾" headers. From what I've read and observed, fox headers don't fit SN95 5.0s only because of the '94-'95-specific bellhousing/clutch fork. In order to use fox headers on an SN95, we need to install a fox bellhousing, clutch fork, input shaft (the '94-'95 5.0s have a longer input shaft) and a longer driveshaft or a spacer to accommodate the shorter setup. This is what I'm planning to do on my car.

ok great i dont need the egr any way thanks ,i like how my bbks fit i just want to move up to bigger ones
You are in same boat as I am. But I would definately go with the advice above, and not take my word for it. A phone call to BBK doesn't cost you anything. This is what the customer service guy told me. They have a different set for the FOX and the SN in 1 and 5/8" headers, but they recently created a single 1 and 3/4" header that fits on both cars. I talked to them about a year ago.
Kurt
This is what I did. Tremec tko600/ bellhousing and longer driveshaft. I also do not have an egr and didn't want the ugly bung with a cap. I like the fit of my bbk 1 3/4 fox headers. The ground clearance is not great,but none of the ones I've installed have been much better. I'm using the same setup on my current project.
Thanks for that info Kevin. I have a 3550 which has the fox style bellhousing. I had always heard you could use Fox headers, but I now know someone who has done it.

The lack of an O2 bung was my original reason for wanting fox headers. My hooker headers accomplished that, but now I need ground clearance. Haha. I have a sad history of doing everything at least twice on this car and those before it.
Edit: did you have a longer driveshaft custom made?
I think most of us share the same history.I have a sad history of doing everything at least twice on this car and those before it.
Edit: did you have a longer driveshaft custom made?
Yes...I cut my aluminum driveshaft in half and welded in a new section. Took it to my machine shop and had it balanced.

I had to have my driveshaft lengthened too. Now they have spacers available so you don't have to go through all that nonsense.

For my 1-3/4" LT's w/ 3" Collector I had a QA1 Tubular K-Member which made the install cake. Only thing I needed was the O2 extenders I bought at Steeda. I don't think the FOX LT's will work with stock K-Member and aftermarket transmission from what I remember. BBK and MAC make 94-95 Specific long tubes anyway that bolt right up. I've had 5 exhaust systems- Stainless Steel, Chrome (3 times) and Ceramic. Make sure you get the ceramic coated LT's. Or get them unfinished and send them to someone for coating. MAC has a distribution center here in Florida so I went and spoke with the sales rep before pulling the trigger. I bought the entire system headers to tailpipes.

The only problem I see with that is that it does not accomodate people that have eliminated their smog and don't want the bung sticking up AND have converted to a Fox T5 with the traditional clutch lever location. I think those are the reasons for using Fox headers.
Are the K-members that much different?

Take a look here:
(I haven't read it yet, but it should be interesting. I'll have to check it out later.)
Well, it's was a link to another site with good info, but apparently that site is frowned upon here. It wouldn't let me post the link.
It is a sticky on using Fox l0ng tubes in SN cars.

The lack of EGR was my original reason for wanting fox long tubes. From the first day I lifted a hood on an sn95 5.0 I've always despised the EGR tube.
Would it be ok to send it in a message? I'd like to see what it has to say.Take a look here:
