First off, I apologize if this is a rehash of a previous thread.

Last year I replaced the factory exhaust on my 2010 2LT/RS LLT V6. I put a cat back MagnaFlow system on. The system I got was designed for the V8 models (competition series model #16580). It mounted up very easily with just minor adjustments. The biggest adjustment was the exhaust tips. The system came with 5" resonated tips. The tips would not work with the openings on the rear diffuser. Rather than have just plain pipe ran out the openings, or having the exhaust released under the car, I had the shop cut the tips off my factory exhaust and mount them. That way it gave a better finished appearance in my opinion.

I am currently looking to replace those tips with some better looking ones. I am currently considering 4" double wall or 4" resonated tips. I am not sure which ones would be best. Any help and suggestions would be greatly appreciated.
