Deciding between this and a slip-on? The RS1 slip-on is the lighter-hit option, while this header-back full system delivers the biggest bolt-on gains.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e\n{\n  \"@context\": \"https:\/\/schema.org\",\n  \"@type\": \"FAQPage\",\n  \"mainEntity\": [\n    {\n      \"@type\": \"Question\",\n      \"name\": \"Does this Trinity exhaust add horsepower on the RZR RS1?\",\n      \"acceptedAnswer\": {\n        \"@type\": \"Answer\",\n        \"text\": \"Yes.
