These systems provide a noticeable performance gain and were designed using SLP's innovative modular technology. This enables consumers to change the performance and noise-level characteristics by switching from bullet-style Loud Mouth resonators, to quieter Loud Mouth II mufflers, in order to suit their individual requirements.

These systems were created using industry-exclusive modular design architecture, so that simply loosening a few band clamps, swapping muffler types and retightening, can change the performance, noise level and sound quality of your Camaro or Firebird. The F-Body Loud Mouth System is compatible with the included race resonator and original Loud Mouth II bullet-type race muffler (Part #31067), which you can purchase separately to gain complete control over both your car’s sounds and performance characteristics. Includes a Loud Mouth resonator.

SLP® - Loud Mouth™ Stainless Steel Cat-Back Exhaust System with Split Rear Exit

Sounds great. Took about an hour to install after the old one was off. The only thing I wish that came with it was the rubber brackets for the exhaust, but other than that 100% satisfied.

SLP® - Loud Mouth™ Stainless Steel Cat-Back Exhaust System with Split Rear Exit

I love it I don’t regret buying it! If you want a loud exhaust this is definitely the way to go!! Especially for what you pay for you can’t argue with that it’s pretty much a straight pipe with a straight-through resonator also Installation was easy.
