Ravens or Flowmasters?

i have a 2.5 liter, 4 cylinder 1990 s10...which should i go with...for 25 bucks i can get either a raven or flowmaster. both are single in and single out...what are the differences between the two and stuff like that? thanks in advance.

I had a raven exhaust on mine, it was alright, I recently switched it over to a flowmaster 40 series, it sould a lot better

Since you have a 4 cyl. I'd go with something as quiet as possible. I'd say go with Raven.
