The Camaro is a legend. This is the best one so far. Convenience, driveability, ergonomics, everything. Right. The wait for the car was so well worth it and it is a treat just to sit in the car. Taking the family for Sonic or to the local cruises is awesome. Everyone gives the thumbs up and appreciates seeing Camaro back and On Duty!

So after driving it all of about 500 miles, it was time to do something to it.

Having been the 6th Camaro we've owned we know what the LSx's have done in the past with Exhaust Upgrades.

Some Long Tube Headers were on tap. After reading up and talking to people in the industry, we decided to give the people at Doug Thorley a call and get ahold of their new "Tri-Y" 1 3/4" Long Tube Header System. The way in which Doug Thorley has engineered their design with these is truly a feat. The 1 3/4" would usually be considered small by others' standards but the flow charactoristics and dynamics under which the exhuast is channeled out of the heads create a paradigm where they actually "flow" just about as good as a 1 7/8" LT Header.

Installation was a breeze as there was no cutting or welding. The removal of the dipstick was about the hardest thing to do and, even taking our time for pics and investigation into the Camaro and how everything went together in the assembly process at Oshawa, realized that it took just under 3 hours of actual labor to remove and reinstall these Long Tubes.

Since the Doug Thorley Catback System was still "in development," we continued with the OEM Catback so that we could see and feel exactly what the Long Tubes alone did to the car. Needless to say, installing Long Tube Headers has got to be one of, if not the best thing, that can be done to the LS3. SOTP and "hell yeah" meters were pegged immediately after installation and the sound was so much better than that stock, passenger car sound.

Made a quick video to demonstrate it with the OEM Catback still installed:

Loving how the car breaks loose around 4500 RPMS. The RPMSs fly up to Redline in a matter of milliseconds now.

Awesome.
