Step-by-Step: Installing an Edelbrock Tubular Exhaust System on a Tahoe
Slide Show
Chevy’s Tahoe and its GMC cousin, the Yukon, are very popular sport-utilities. They’re roomy, good looking, and reasonably powerful—and are just begging to be hopped up.
Working with AutoDynamics® of Akron, Ohio, We procured a 1996 four door, four-wheel drive Tahoe to see if we could unleash the vehicle’s hidden potential, yet keep it smog-legal.
One of the upgrades the Auto-D guys was an Edelbrock Tubular Exhaust System, or TES. More than just a set of headers, the TES replaces the restrictive stock exhaust from the cylinder heads to the catalytic converter. Unlike header designs that make either low rpm or top end power, the TES has what Edelbrock calls “dual diameter” primary tubes that build multiple torque peaks. Those peaks produce power across the engine’s entire rpm range without the peakiness most headers are guilty of.
The 50-state-legal TES for the Tahoe is made from 17 gauge stainless steel, has connections for stock emissions equipment, and has OEM style connector flanges to make hookup a no-brainer.
Once the Edelbrock system was installed, we took the Tahoe to the track to run some 0 to 60 times (a more real-world test of performance on a street-oriented vehicle). The result? The Tahoe with the TES ran 0 to 60 four-tenths of a second quicker than it did with the stock exhaust system.
While installing an Edelbrock TES is a little more involved than bolting a set of headers on an old Chevy pickup with a small block, it isn’t that hard, either. Follow along as AutoDynamics bolts on some tubular horsepower.
