	High technology headers improve engine efficiency and increase power. Click an image to View Full Size Rolling Thunderz has expert knowledge for upgrading Viper cylinder heads, with the unique ability to provide custom cylinder head modification services that are specifically designed for each type of cylinder head, from the 1st generation Viper RT/10 heads to the 2nd generation Viper GTS & RT/10 heads and the latest generation Viper SRT heads. This Viper cylinder head package consists of professional porting modifications, a high technology valve job with larger and superior stainless steel 2.02” intake valves and 1.60 exhaust valves. New Viper valve springs are installed with the use of the original valve spring retainers and valve locks. The head is resurfaced and professionally assembled. This Level 1 cylinder head package provides a more economical upgrade for Viper enthusiasts who want to retain the original valve-train equipment with the use of superior Mopar Performance stainless steel Viper valves. Performance increases of 30 to 40 hp can be expected with this cylinder head package, when good air intake and exhaust system upgrades are already installed.

	Exhaust tube headers can provide a significant increase in exhaust air flow and improve engine efficiency. Click an image to View Full Size The production exhaust manifolds on a Viper are considered to be a performance restriction, particularly for a large displacement V10 engine that requires more exhaust flow capability. The installation of exhaust tube headers can provide a significant increase in exhaust air flow and improve engine efficiency. The key ingredient for superior performance in a Viper Header is the shape of the collector, where five exhaust tubes merge into the collector pipe. A race header style 5 into 1 merge collector with a gradual transition allows the exhaust gas to maintain velocity. Sustaining a high exhaust velocity is the key to allowing the exhaust system to create efficiency and thereby produce more power. Viper High Performance Exhaust System The production exhaust system is considered to be restrictive for a large displacement V10 engine. The installation of a high-flow exhaust system with larger diameter exhaust pipes and low restriction mufflers will improve the Viper engine’s breathing capabilities and increase power and performance. 1997-2002 Viper RT/10, 1996-2002 Viper GTS - Bolt on replacement for production rear exit exhaust - Low restriction with a performance sound - 304 stainless steel construction - 3" diameter for high volume flow - Factory style band clamps - Exclusive laser etched Viper logo on polished stainless steel exhaust tips with rolled rims
