1 3/4 equal length headers??????

Dark_5.0 · 11-16-2006, 11:41 PM

I feel I need better headers than the 1 5/8 BBK equal length headers that I have for my 331 stroker.

I just bought new Mac exhaust that costed a left nut so I am sticking with shorty headers over longtubes.

If anyone knows of a company that sales them let me know.

I've never seen equal length shorties in 1 3/4". The only two 1 3/4 shorties that I know of are the MAC and Bassani unequal length (you can find them at Anderson Ford).

Yes, I seen the un-equal's in that size, we put some on a near stock 302, yea i know, the guy had some laying around, and he didnt have anything else to use, it actually ran pretty good....but for a 331 that would be a hot ticket i would guess.

For the price of the Bassani 1 3/4 headers I can buy long tubes and a new X-pipe.

Mac 1 3/4 shorties it is.

Thanks guys,

I chose the MAC as well - they fit well and still look good (coated version). Power wise I'm happy.

if you can get long tubes and a new h-pipe for the same cost as the shorties, then go long tubes. you cant compare long tubes to short headers

richs347 · 11-18-2006, 07:18 PM

You have to admit, the long tubes would kick the short tubes butt at this power level. However, I know I have to remain emission legal, get it by a blowshield, and get over speed bumps on a street driven car. If I had a full on race car where the last 25-35hp was really important that would be my choice.....

why cant long tubes pass a smog test or speed bumps??

richs347 · 11-19-2006, 08:26 PM

No one makes a long tube header that is emissions legal. They figure the only people who use long tubes put them on race cars and they won't spend the $1000's of dollars to make an attempt to get them past the EPA. The 02 sensors are also not in the usual spots which makes running a vehicle in closed loop more difficult. The long tubes hang down further below the engine on the later Mustangs. They don't hang as far down on the newer cars though.

i looked at the bbk web site and see that all the long tubes are listed as non emisions legal. here in the county that i live in we dont have such a problem- no emissions testing at all.
