			<description><![CDATA[I'm currently running RA manifolds with 2.25" outlets, with a full 2.25 exhaust with crossover and the head pipes are 2.25" 90° mandrel bent. 
 
Would there be any point/benefit to stepping up to a 2.5" exhaust like pypes kit for instance even though the manifold outlet is only 2.25"?]]></description>

			<description><![CDATA[Hi All, 
I have bought 74 exhaust tip repro's and would like to know dimensions for placement. How far should the pipes be from outer edge of the body and how far from the bumper bottom edge. Trying for the factory look. Thanks in advance. 
Cheers, Pete.]]></description>
