The second-iteration Viper, codenamed "SR II" was introduced in 1996. The exposed side exhaust pipes on the RT/10 roadster were relocated to a single muffler at the rear exiting via two large central tailpipes during the middle of the model year, which reduced back pressure, and therefore increased the power to 415 hp (309 kW; 421 PS). Torque would also increase by 23 lb⋅ft (31 N⋅m) to 488 lb⋅ft (662 N⋅m). A removable hardtop was now available along with a sliding glass window. Some steel suspension components were replaced by aluminum, resulting in a 60 lb (27 kg) weight reduction.[17]

Later in the 1996 model year, Dodge introduced the Viper GTS, a new coupé version of the Viper RT/10. Dubbed the “double bubble”, the roof featured slightly raised sections that looked like bubbles to accommodate the usage of helmets and taking design cues from the Shelby Daytonadesigned by Pete Brock.[18] More than 90% of the GTS was new in comparison to the RT/10 despite similar looks. The GTS would come with the same 7,990 cc (8.0 L; 487.6 cu in) V10 engine but power would be increased to 450 hp (336 kW; 456 PS) at 5,200 rpm and 664 N⋅m (490 lb⋅ft) of torque at 3,700 rpm. The 1996 GTS would be the first Viper to be equipped with airbags and also included air conditioning, power windows and power door locks as standard equipment.[19] The Viper GTS would be chosen as the pace car for the 1996 Indianapolis 500
