SLP Powerflo

I have a no mod 2004 automatic. I'm trying to make up my mind on an exhaust system. I've narrowed my choices down to either the Magnaflow or the SLP powerflo. Either will be catback. What are the weight savings between the two and the stock system? Is either one more prone to droning? Is the SLP louder since the mufflers are smaller? They both are priced about the same. Any help will be appreciated.

Thanks,

Trace

Volume-wise, its definetely not louder...it is definetely deeper, and has a great tone...but not very noticeable at all.

I wanted something louder, so after a few more systems, I finally have the SLP PowerFlo and I'm keeping this one! The mufflers are identical to the Borla Stingers, so anything you read about the Stingers will be true with the PowerFlo. They can drone, but nothing that I think is intolerable. Also, with the one piece exhaust tip, they always stay aligned! That was another problem with all the other systems I owned...the tips were never straight.

Here are a few videos of the PowerFlo I took for some members. I still have the Magnaflow X-pipe installed, but other than that, the car is stock.

PM me if you have any other questions
