{"product_id":"mach-shorty-cat-back-exhaust-kit","title":"Mach Shorty Cat-Back Exhaust Kit","description":"This Solo Performance G8 Mach Shorty CAT Back Exhaust Kit is specifically designed for the 2008-2009 Pontiac G8 GT and GXP models with either manual or automatic transmissions. The kit is constructed from polished stainless steel, both inside and out, ensuring durability and a premium appearance. It includes all the necessary components for a complete installation, such as exhaust tips, J-pipes, a muffler, and clamps.\n\nThe \"American Muscle\" classification signifies a more aggressive and louder exhaust note compared to milder systems, making it ideal for enthusiasts seeking a distinct sound profile. While the exterior sound is rated a 7 out of 10, the advanced J-pipe design effectively minimizes interior cabin noise, keeping it around a 4.5 out of 10 and avoiding unwanted drone or rasp. This balance allows drivers to enjoy the aggressive exhaust note during spirited driving while maintaining a comfortable cabin environment for daily use.\n\nWhen the V8 transitions to 4-cylinder mode, the sound has a noticeable, sharper octave change. While driving uphill, the exhaust can be heard contributing to the \"pull\" but does not develop into a drone or hum. Feedback suggests the 4-cylinder mode might produce a \"guttural\" sound, which some users may find less than ideal, and it is recommended to \"tune out\" this mode if it's a concern. The larger 3.5\" dual tips option is available but requires the GXP valence. Free UPS shipping is included for the continental United States and most of Canada.","brand":"Solo Performance","offers":[{"title":"Default Title","offer_id":52663715234104,"sku":"994194-SL","price":1096.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687679685.webp?v=1784329123","url":"https:\/\/store.motormia.co\/products\/mach-shorty-cat-back-exhaust-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
