- Description:
The stock Y-Pipe was replaced with a high-flow model from the SHOShop.
This replacement included redesigned downpipes, high-flow catalytic converters and a redesigned Y-pipe. The system
was purchased used and one of the two cats had to be replaced with a new one due to a dent.
- Why:
The exhaust configuration of a stock SHO is commonly referred to as a "2-1-2" layout: two exhaust manifolds feed through two separate catalytic converters; the exhaust then combines into a single pipe, goes through a single resonator, and around the gas tank; the exhaust then splits back out into two tailpipes with separate mufflers. The stock system is light-grade stainless steel; the pipes will show some surface rust but will last quite a long time in most climates.
The SHO's stock exhaust system is very quiet, but it unfortunately creates a lot of backpressure. This reduces the overall flow capabilities of the engine, which reduces the ultimate available power.
