{"product_id":"11361","title":"ECS Tuning B7 RS4 Exhaust H-Pipe Kit","description":"\u003cp\u003eGot a couple hours in your afternoon or Saturday? Here is a great way to increase the sound quality of your RS4 along with increasing top end performance. ECS RS4 H-Pipe eliminates your factory center resonator with a H-pipe that really enhances the sound quality of your RS4 without any sacrifice in interior cabin drone. Dyno charts have also shown a increase of 3-5hp between 6-8000 rpm. Installing this ECS H-pipe still allows use of the factory flapper valves in the rear mufflers. With the ECS H-pipe installed the difference between the flapper valves being open or closed is much more dramatic that with the stock exhaust system. \u003cbr\u003e\n\tQuite simply this is a fantastic way of increasing sound quality of your RS4 without having to go through the large expense of replacing the whole \"cat\" back system. This upgrade is a simple bolt on modification and measures 2.25\" in diameter. Simply cut the center resonator out (between the center resonator \u0026amp; the rear mufflers) \u0026amp; install the ECS H-pipe using the factory sleeve clamps \u0026amp; two supplied clamps. \u003cbr\u003e\n\t \u003cbr\u003e\n\tLimited lifetime warranty to the original purchaser.\u003c\/p\u003e","brand":"ECS Tuning","offers":[{"title":"Default Title","offer_id":45976562663728,"sku":"11361","price":683.83,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/7582\/4176\/products\/676419_x450_3dcf8c1c-e44d-41b0-9749-f0d50e9cbbcb.jpg?v=1695088239","url":"https:\/\/es-performance.com\/products\/11361","provider":"Eurosport Performance","version":"1.0","type":"link"}
