H or X CROSSOVER?

CFD244 said

Hi Folks

Running a 340 auto with an XE262 cam, 1969 HP manifolds and a factory TQ on a 1971 Demon (3.23 gears). Looking to purchase a 2 1/2 TTI exhaust and see that there is an X option and an H option for crossovers. I am looking for something with no drone on the highway, and not obnoxiously loud. This is a cruiser with 2 60 year olds taking a Sunday drive. What differences would I hear between the two. @VOETOM your input would be appreciated.

Thanks FABO

IMO, since I have both systems in place on two cars, it’s more about sound since the difference in HP is so little it’s silly.

The “H” pipe has more of that traditional muscle car sound while the “X” pipe will smooth out the exhaust pulses mellowing the normal idle pulses your used to hearing. On the mid & top end, the higher up the rpm scale you go, the sound changes into a screeching banshee sounding like it’s a thousand rpm higher.

Ya wanna scare the kids in an awesome sounding high reving car, install the X pipe.
The traditional muscle car sounding like a beast? Use the H pipe.

Muffler wise, this is your call. Turbo mufflers normally have the most quite sound, longer the muffler, the more quite it will be.
Dynomax mufflers in an extended case length are pretty quiet. There’s also the Walker SoundXF mufflers that are close to stock sounding.
