Yes! After more than
a year of effort in finding a competent manufacturer, we finally
hit paydirt in the year 2000! The winter of 99 - 2000
the prototypes, manufacturing jigs, and assemblies were completed
and The Other Guys Performance and Exhaust
Products are making these 3800 Series II headers today!
The Other Guys have been
instrumental in design and manufacturing for almost all the
major header companies since the 60's!

With a little persuasion,
these guys realized the performance and market potential of
the 3800 engine and agreed to kick off their product lineup
with the 3800 headers! These photos are of a set bolted
to a test engine for photo purposes, awaiting installation on
the THRASHER "So-Lo" show car. Note that the production
flex connector differs from this early prototype.
Some of you seasoned racers
may recall that THRASHER had an entirely different header design
on our Regal GSX development car in the winter
of 1999 - early 2000. In a nutshell, we could not find
any manufacturer willing to produce the previous design
at a reasonable cost due to the complexities of mandrel bending
the 3 inch pipe accurately to ensure proper clearance and fit.
Another factor in changing from the previous
design was the CARB EO certification process and almost all
our email indicated everyone seemed to want the "3
into 1" header look. This plus the visual appeal of the
high luster finish really knock your socks off when you pop

original 3800 headers built for
THRASHER's "So-Lo" Show Car!
headers will only be available in the high luster electro-less
nickel plating shown in these photos. The finished headers
are dipped (not sprayed) so the plating completely covers
all surfaces both inside and out which greatly increases corrosion
resistance. The Other Guys have repeatedly stressed
that is the highest quality finish available for exhaust products
and and will not deteriorate from excessive heat, unlike many
other coatings available today.
Also, it is important to note that
these headers are manufactured with 14 gauge tubing and all
OEM style flanges throughout. Notice also the special
flex connector at the downpipe which allows freedom of movement
from engine vibrations. The output is 3" and slips
perfectly into the original catalytic convertor for easy welding
when the stock downpipe is cut off at it's junction.
These headers are of the highest quality
and the Other Guys are so confident of their workmanship
they offer a Full Unlimited Lifetime Warranty
against defects and damage,"even if
you run over them with a truck" - their exact
words, not ours.
bottom line is ...what are the performance gains for
these headers over the stock exhaust manifolds?
Dyno testing of
the development car before and after and have reported
the following: These dyno tests were performed
on a bone-stock 2000 GTP as delivered off the showroom
floor with 3000 miles on the clock, with absolutely
no mods whatsoever! CLICK

That's right - stock pulley, stock exhaust,
stock air intake and stock paper air filter! This GTP
produced a respectable 190 HP at the wheels in stock trim,
typical of most showroom stock cars. With the only change
being the headers, still running into the stock cat and mufflers,
this GTP showed a phenomenal 18HP and 16 Ft-Lb
gain at the wheels! Furthermore, the maximum boost level
dropped to 6 psi (remember, this is the stock pulley)!
