Longtube questions...Have both SN95 and FOX specific ones

[Last5.0]

Ok, I have a '95 that I'm putting longtubes on. I have two sets....one is made specifically for a '94/5 and is 1 5/8" with 2" collectors and the other is for a FOX but in 1 3/4" and 3" collectors. With my mods, I'm wanting to go with the 1 3/4" but I noticed a few differences....First, no EGR tube (not a problem, I run no EGR). Second, the O2 bungs are facing the outside instead of the inside like on the '94/5 specific (still, no biggie, I'm sure it doesn't matter). Lastly, I noticed the primarys are routed different between the sets. On one set the front two go down first then back where as on the other set the front two andgle back and the rear two tubes go straight down and back. Does anyone know if this will make a difference with clearance issues (maybe with the steering knuckle)?? Also, I have a Mcleod SFI bellhousing which uses a longer than FOX fork (but shorter than SN95) and a DSS 7 qt low profile pan.

Even if they do fit i would not go with the 1 3/4 primaries, you will loose a lot of bottom end torque.

mine were for a fox body and i took my stock headers in, got the bung cut off and installed on the new headers then made my own egr tube with copper tubing. doesnt leak and works fine. thats only cause i got the LT's and o/r hpipe for $75

I think I'd go for the 1 3/4 in that case.
