Which Challenger exhaust tips for Summit exhaust?

[cudazappa]

Figure someone here must know more about exhaust tips than me.

I purchased this kit from summit racing:  http://www.summitracing.com/parts/sum-680142/overview/make/dodge/model/challenger/year/1971

I have the dual valance installed, and the mufflers reside where the resonators would.  Which tips should I be using?  I've seen some late-model challenger tips also used on an E-body, too.

Not concerned to much about correctness, but anything will look better than the straight pipes right now sticking out past the valance.
