About Cat-Back Exhaust Systems — Brands, Fitments & Buying Guide ▾

Cat-Back Exhaust Systems — Authorized Dealer for Every Major Brand

A cat-back exhaust system replaces everything from the catalytic converter back — mid-pipe, muffler, resonator, and tailpipes — for a deeper sound, weight reduction, and meaningful power gains on most platforms. SP Engineering stocks cat-back systems from every major performance manufacturer with fitment for hundreds of cars and trucks. We've been an authorized dealer since 1996 and ship worldwide from California.

What a cat-back system actually does

Reduces backpressure — most factory exhausts are restrictive past 3,500 RPM. A 2.5" or 3" mandrel-bent cat-back unlocks 8–20 hp on most NA platforms, 15–40 hp on turbocharged builds.
Sound profile — deeper baseline, more aggressive at WOT. Many systems offer multiple muffler choices (Touring / Sport / Race) to dial in volume.
Weight savings — stainless or titanium versions can shed 20–40 lbs vs OEM cast/steel.
50-state legal — cat-backs keep your catalytic converters intact and remain emissions-compliant.
