2005 Pontiac GTO FUN
So my Dad bought a GoPro for Christmas.... Told him I'd make sure it works.
So I took it out for some fun and a little cruise around town, finished
with a little quarter mile run. Enjoy!

One of our customers sent us this video of his '72 402 Chevelle after he
finished installing a Pypes X-pipe and Violator mufflers. He said, "As you
can probably tell, VERY satisfied with the results. Thanks for a great
Thanks for the video and kind words.
Chevelle movie for pypes 12-08.wmv
'70 chevelle with 555 ci big block. 11:1 pump gas engine with a big solid
roller, AFR 335's, vic jr., pro-systems HP1000 carb, 2" headers, 3"
collectors, full 3" duals with x pipe running Pypes Race Pro mufflers.
Electric cutouts are installed. Car has a TKO600 trans and 12 bolt rear
end in this video. GForce GF5R and Ford 9" are going in this winter. Engine
made 792hp/701tq at the flywheel on a superflow engine Dyno. Chassis Dyno showed 618rwhp AT 5500 ONLY
- data did not log up to the 6800 it was run to due to a Dyno error. Based on the 70hp
increase from 5500 to 6800 rpm on the engine Dyno (horsepower peaks at
6800rpm), we are guessing we have around 670-690hp at the wheels. Car will
be back on the Dyno in
the spring. Engine built by Mike Lewis of Lewis Racing Engines,
65 Nova / 2.5" X-pipe system / Racepro
This 1967 Nova has a Pypes 2.5" header-back system with a performance
enhancing X-pipe. The owner chose Pypes Racepro mufflers for their mild
sound and great flow rating.
69 Judge / 3" Pypes X-change system / Racepro
The owner of this 1969 Judge chose to install a Pypes 3" headerback system
with the optional X-change crossover. The X-change allows him to easily
switch from full Exhaust when he's
cruising to after-X cutouts when he's racing. Pypes Racepro mefflers were
also chosen for their great flow rating.
