Interested in long tube headers

dogmatin · 10-22-2009

Hello, I own a 2004 3.8 v6 mustang and I recently had an exhaust installed. I have
Pype's catted X- pipe for v6 and SLP loudmouth catback. My question is I wanted to get pacesetter long tube headers and I didn't know if they would fit. I'm trying to get a throatier sound and wondered if shorty headers really make a difference.

shorty headers give you a more raspy tone andd long tube headers give you that amazing rumble

The Pacesetter L/Ts should fit fine as long as you have a manual transmission. I read recently that Pacesetter L/Ts won't fit on an automatic. They'll fit but you will also need to swap your midpipe for a shorty midpipe that is compatible with L/T headers.

yes, and yes they should fit the only difference is internal.. the heads and block are exactly the same from 3.8 to 3.9

thanks! then what is the advantage of going wiht a shorty rather that a long one?

Markstang690 · 10-22-2009

no the advantage is in getting the long one.. shorty's flow the same as your stock header.. longtubes flow and sound better

Shorties will give you nothing; your stock headers flow very well. Long tubes will give you some extra power but be careful if you have to pass emissions.

I have high flow cats on my X pipe, will long tube headers bolt right up to my X pipe.

Thanks for the info by the way very helpful.

No. It would have to be custom fabricated......
