Hedman/summit/jegs

Yes sir there the elites by hedman, they cost me a pretty penny,had them for a while seem to hold up very well though.Sorry not sure what sp? stands for.i looked at tti systems, flow master, dyno max.. prices do vary alot, i will see what the shop tells me tomorrow, i would hate to not use the pipes i already have. they were free so if i have to buy a pre bent system i will.
