H-PipesWith their larger than factory diameter these kits are perfect for enthusiasts looking for an off-road/racing H-pipe. These pipes maintain your low end torque while offering you a free flowing size and construction for more power in the midrange up to your shift point!
X-Pipes
Designed to bolt on quickly and add up to 12 horsepower! Manufactured to free up horsepower by reducing the effect of a V8 engine's out-of-sync firing order, occurring when two cylinders on the same bank fire within 90° of each other and cause a crowded condition in collector and exhaust pipes. X-pipes also promote balancing and equalizing, which decreases negative harmonics and increases exhaust velocity making you more power! These off-road/racing X-pipes fit manual transmissions applications only.
Starter Tubes
FlowTech's 2.5'' diameter aluminized starter tubes give you a larger diameter choice but can still attach to any OE X and-H-style pipe on your 1986-1993 Mustang. With these pre-formed OE style tubes you can choose the sound style and tailpipe configuration you want!
