7 6 Install m u f f l e r and e x h a u s t system ( n o t included with the
t u r b o s y s t e m ) as shown in f i g - 2 6 . Because of various
v e h i c l e / chassis c o m b i n a t i o n s , the illustration provided is
g e n e r a l , but typical of the exhaust system r o u t i n g .
N O T E : The factory m u f f l e r and exhaust system are NOT s u i t a b l e
for t u r b o c h a r g e d e n g i n e s . The entire exhaust s y s t e m , f r o m the
turbo down-pipe through to the tail p i p e , should be three inch_diam
eter_, including the muffler. Use of a s m a l l e r m u f f l e r or e x h a u s t
p i p i n g will result in significantly inferior performance. A separate
3" high-flow e x h a u s t s y s t e m is available f r o m GALE BANKS
E N G I N E E R I N G . T h i s e x h a u s t s y s t e m i n c l u d e s a special low
rest ric t ion 3" core m u f f l e r , p r e - f o r m e d tubing sections and all
comp one n ts n e c e s s a r y to install the c o m p l e t e exhaust s y s t e m .
The B A N K S 3" exhaust system is REQ UIRED for emissions legal
a p p l i c a t i o n s . Use of any other exhaust with the turbo system is
not emissions l e g a l .
For tho se w i s h i n g to do their own exhaust system f a b r i c a t i o n ,
the following r e c o m m e n d a t i o n s should be f o l l o w e d :
a. Be sure to use a h i g h q u a l i t y , low rest rict ion 3" core
m u f f l e r , designed for turbocharged diesel applications.
( M o s t 3" mufflers available f r o m muffler shops are low
q u a l i t y , high restriction " e c o n o m y " replacement m u f f l e r s ,
usually based on a 2 - 1 / 2 " or smaller c o r e . )
b. M a k e all bends as gradual as p o s s i b l e . Align all weld
j o i n t s as carefully as pos sibl e so the exhaust flow will
not experience " s t e p s " in the tubing. See f i g . 2 6 A .
c. Do not " c h e a t " bends or make miter-weld j o i n t s . These
types of bends are too abrupt for proper exhaust f l o w .
d. M a i n t a i n adequate clearance to c h a s s i s , f l o o r b o a r d s ,
d r i v e l i n e , moving suspension p a r t s , e t c . Suspend exhaust
t u b i n g in r u b b e r hangers to allow for engine m o v e m e n t . The
o r i g i n a l h a n g e r s may be r e u s e d if in good c o n d i t i o n .
