Narrowed it to these 2, I'd prefer Magnaflows because I like the sound but my shop (who sells both) suggested the Turbo's (not the Welded) saying they are similar to the Magnaflows without the name recognition and price tag. Although I've listened to clips on youtube and others, are the Turbo's a good muffler? I have an 05 LS that I just had leveled/shocks/wheels/tires, wanting to finish this off. Not looking to start some wide ranging debate about Borla/Flowmaster etc. My question is: Am I sacrificing sound and quality by going with Turbos vs put the money into it now because the Magnaflows are that much better? I want a nice low rumble, not obnoxious with least amount of drone. I am going to run from the cat back with dual outs. Thanks
