SLP Performance Parts Increase Trap Speed - Trans Slam

Underneath this typical T/A tail is the restrictive and too-quiet stock muffler. The dull aluminum tips don't enhance the Bird's look either.

Swapping an exhaust system at the track for same-day testing can be a challenge, but the SLP unit bolted right into place and fit well. In order to remove the stock exhaust, the pipe above the axle was cut with a hacksaw. Looking at the SLP tubes, note that the high-flow Y-collector doesn't cause any restriction going into the dual tailpipes. The stock exhaust flows into the restrictive (low-flow) muffler, then into the tailpipes. Pipe size differs between the two systems with 3-inch into 2.50-inch tails for the SLP versus 2.75-inch into 2.25-inch tails after the muffler for the stock system.

We prefer the looks and the powerful sound from the new SLP exhaust. It's all stainless for lasting luster. The dual-outlet, polished tips remind us of the old Goat and T/A splitter tails-definitely cool! Picking up another tenth was cool, too!

Hidden in a crowded engine compartment, the stock wires lack the appeal most gearheads want. At 8 years old, they were due for regular maintenance-type replacement. The original 80,000-plus-mile plugs were still in place, but we didn't have enough track time to replace them.

Visually, the construction and appearance of the LiveWires is much better than stock. SLP tested the LiveWires versus stock wires and saw 3 hp more on the engine dyno. "These wires feature a spiral wound core to thwart electronic interference, and they have low resistance for improved performance. LiveWires also have silicone insulation and heat-treated glass-braid sleeves that resist moisture and chemicals and can withstand temps of -76 to +1,400 degrees F.

Still hidden but more noticeable, the LiveWires give the LS-series engine some performance appeal. The motor ran noticeably smoother, and the throttle response improved. Gains were observed in the 60-foot, 1/8-, 1/4-mile and trap speeds.

Here, the T/A launches towards another low-13 after trying the power extras. Consistently timed throttle depression helped us achieve clean launches without the tires going up in smoke. SLP's 350hp Pac lowered the e.t. 0.32 and added 3.13 mph. The LiveWires responded with 0.04 e.t. and 0.22 mph. Combined gains were a 0.36-e.t. reduction and 3.35-mph increase.
