Dynomax Hemi super turbo mufflers Seriously, someone did a shootout and they flowed near the top yet remained near the bottom for sound output.

Go to the 50 series Flowmasters. They reduce interior noise significantly. Go to their site and look at the interior/exterior noise chart to get an idea. If you don't have one already, then adding a crossover will reduce noise as well.

Just find the longest straight through perforated core muffler you can fit under the car. Anything baffled (flowmaster) is going to kill flow.
I am using one of these on my 3" catless Y to 4" rear section and its much quieter than expected.
Ill try and have a video by next weekend.

I found dynomax super turbo but there are two choices for me which one should I getting? The case long is 20 inch or 14inch? 2.5'' inl/out
Will I get diff. power and sound from the case size?

Hated the blowmasters on my car when it was NA. Since I went the FI route they became "tollerable" but I still did not like them. I recently swapped them for a set of the larger case Dynomax Ultraflo's and love them. I can't however tell you how loud they will be NA since the turbo's do a great job acting as mufflers.
