Straight Piping

Asked by Jun 06, 2015 at 07:19 PM about the 1993 Ford Thunderbird LX

Question type: Car Customization

My TBird currently has a set of the 40
series Flowmaster under her right now. I
want a more aggressive, and loud for sure,
sound out of her. I understand the problem
with straight piping is:

#1 butthurt neighbors but who cares
#2 back pressure

Back pressure slows down the pistons (I
think either that or rods) as the reach the
top that way they don't slam when they
make it up. But I am also under the
impression that with my vehicles age, it
won't do much damage to my car? Any
Tbird rider out there that have straight
piped theirs? I would like to know if it is
okay for me to go ahead and continue with
my build. Im doing a steering shaft
modification that allows me to put a set of
long tubed headers, so once that is done I
would like to straight pipe.

Thanks in advance!

Straight pipes only work on high powered supercharged 1/4 mi. dragsters & P-51 aircraft. Some back pressure is good for scavenging, (it's sort of a vacumn when the exhaust valve opens). This open & closing cycle also determins the length of tubes. Also straight pipes can cool the cylinders too fast & warp the valves & foul the plugs. The Pistons don't slam, only pushes the exhaust out during cam duration & overlap. 1. If a deeper aggressive sound it what you're after choose a different muffler. I like a Raven muffler & cat. 2. Have a muffler shop with a hyd. tube bender make you a custom 3" single pipe will flow more than duels. Use a 3" inlet & outlet muffler & perf cat too. It will sound great. 3. Buy a chambered exhaust like Walker, no mufflers are used. The outer pipe is chrimped like sausages & the inner pipe is perforated with a lot of holes that is a baffle.

I studied & built headers. Also I am a 40 yr. experienced aircraft tech.

3" single pipe compaired to duel exhaust is like comparing a trumpet to a tuba! See? See how Yamaha designed the exhaust sound for the Lexus LFA.
