At stock ride height, on H\u0026amp;R springs, and most aftermarket springs, you will be perfectly fine with the 4.5”. We compare it to running a nice front lip on a slightly lowered car — you need to drive with your surroundings in mind. This exhaust is the best sounding and performing option we make, but keep in mind it is the largest diameter available, so you will have a little less under-car clearance.\u003c\/span\u003e\u003c\/p\u003e","brand":"Rvng RaceWorks","offers":[{"title":"Silver","offer_id":67602855395422,"sku":"RVNG-EXH-G80-4TS-RES-SI","price":2799.99,"currency_code":"USD","in_stock":true},{"title":"Black","offer_id":67602855428190,"sku":"RVNG-EXH-G80-4TS-RES-CK","price":2799.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0232\/4721\/files\/258EB977-73A7-40F2-865C-7A3F80800CC3.jpg?v=1790875168","url":"https:\/\/slrspeed.com\/products\/rvng-designed-4-5-true-single-valved-exhaust-system-g80-g82-s58","provider":"SLRspeed","version":"1.0","type":"link"}
