I just ordered a off road Mac H-Pipe W/ long tubes and was about to order the flowmaster 40's cat-back for it. I have listened to about every clip out there eventhough its hard to get the full effect from a sound clip the flowmaster 40's sounded great and they have been the most recomened. I did not put the order in yet because while i was looking for it i ran accrost what sound like a realy good price on a cat-back from Stainless Steel Systems. The mufflers look like glass packs and the add said low restriction mufflers. I like it because it is all stainless and being from wisconsin and driving this 50mi one way to work in the winter months i dont want anthing thats going to rust right away. I gess what im asking has anyone heard anything about SSS, am i going to get what i pay for?, and would the less restrictive mufflers mak my car sound like a rice burner?
