Product Description

Give your Corvette a bark to match its bite with SLP's Loud Mouth exhaust system. Constructed from mandrel-bent 304 stainless steel, this bolt-on system offers up to a 15-hp gain and a 20-lb. weight savings over stock. Detailed instructions, a limited lifetime warranty, and all hardware necessary for installation are included.

LOUDMOUTH FEATURES - Part number 31077

  • The LoudMouth system is a race-inspired system. There is no packing or other obstructions within the race resonators - they are completely hollow and are much louder than the resonators included with LoudMouth II systems. This is basically straight pipes with nice tips, and is the most aggressive system you can buy for your C6.
  • Qty 4 - 3.5" OD Round/Dual Wall/ Slash Cut/ 304 SS High Polish - TIPS
  • Qty 2 - High-Flow Bullet Style Loudmouth Resonators
  • Modular design can be interchanged with Loudmouth II Bullet Mufflers in 1/2 hr.
  • 304 SS Mandrel Bent 2.5" O.D. Over Axle Pipes.
  • All Clamps/Hardware and Instructions are included to complete the installation.
  • LOUDMOUTH II FEATURES - Part number 31078

  • LoudMouth II is a bit quieter than the LoudMouth system in that it has internally packed resonators for a slightly quieter (but not quiet!) and more tuned sound than the straight pipes of the LoudMouth system.
  • Qty 4 - 3.5" OD Round/Dual Wall/ Slash Cut/ 304 SS High Polish - TIPS
  • Qty 2 - High-Flow Bullet Style Loudmouth II Mufflers
  • Modular design can be interchanged with Loudmouth Bullet Resonators in 1/2 hr.
  • 304 SS Mandrel Bent 2.5" O.D. Over Axle Pipes.
  • All Clamps/Hardware and Instructions are included to complete the installation.

    If you want to change the loudness of your existing LoudMouth or LoudMouth II system, resonators are available separately as shown below. This will not include tips or pipes and will allow you to tune your sound the way you want without having to purchase an entirely new full system.

  • Benefits of Big Brake Kits

    Big Brake Kits give your vehicle that Supercar look and feel, and exceed stock performance in two areas. First, larger rotors increase heat capacity. Second, stiffer calipers and stainless steel lines reduce system compliance.

    The key, however, is to increase heat capacity and reduce compliance without upsetting the stock front to rear brake torque ratios. If the brake upgrade you select adds too much front torque (as many do), you reduce your car's ability to utilize the tractive capacity of all of the tires to the maximum practical extent (even on ABS equipped cars) and you therefore create performance sacrifices. In addition, too many pistons or pistons that are too large will make the brake pedal much more difficult to modulate, which limits a driver's control of brake input on the race track.

    Advantages of StopTech over other brake upgrades

    • Shorter Stopping Distances
    • Better Brake Modulation
    • Firmer Brake Pedal
    • Less Brake Fade

    Feature Benefit Summary

    • Balanced Brake Upgrades with optimum brake bias offer the shortest stopping distance with the best pedal feel
    • StopTech's patented AeroRotors® with the best airflow available result in better cooling, less fade and longer rotor and pad life
    • The stiffest aftermarket calipers with patented bridge result in better clamping under hard braking and less pad taper
    • Track testing of new applications ensures optimum performance

    What’s included?

    • Calipers: ST-40 (4 Piston), ST-60 (6 Piston)
    • 2 piece floating directional AeroRotors with hats (pre-assembled)
    • Stainless steel brake lines
    • Caliper mounting brackets
    • Street performance pads

    Caliper Color Options

    Note: Silver, Yellow, Blue and Gold calipers have up to a 30 day lead time. Yellow, Blue and Gold are $200 extra per axle. No extra charge for Red, Black and Silver.


    Rotors are available in slotted or drilled and with/without gold zinc coating. Drilled rotors are $100 extra per axle. Gold zinc coating are $70 extra per axle.

    The anti-corrosion gold zinc coating benefits customers who live in cold climates where snow and road salt are commonly encountered, and customers who would prefer to not have visible surface rust on the vanes and outer circumference of their rotors. Zinc coating does not have a negative environmental impact like other coatings.

    Brake Pads

    The calipers in this kit comes with Axxis Ultimate performance brake pads. The performance pads included with kits are suitable for both street and light track use such as Autocross (1 lap at a time). For more aggressive track use or race use, it is very important to select pads appropriate to the type of driving. If you wish to order alternative pads separately please contact us.

    Caliper Clearance

    Most 17” wheels will clear the outer diameter of the caliper for a 332mm kit. For a 355mm kit, a minimum 18” wheel is typically required. The more critical clearance, however, is the gap between the spokes of the wheel and the face of the caliper. Do not assume that a larger-diameter wheel will automatically clear the face of the caliper. StopTech recommends at least 2mm of additional clearance. See the Wheel Fitment Drawing page on the StopTech website for more specific measurements, at
    Note: Final fitment of the wheel to the caliper is the responsibility of the customer.
