what exhaust system is the best for a bone stock 1985 z28 that will sound good and will also help performance at least a little bit...performance has a major priority over sound but both would be absolutely amazing. ive heard that flowmaster systems have been dyno proven to reduce horsepower which surprised me, but i'm not sure so if anyone can dispute that with actual dyno numbers not "o it feels like ive gained" that would be awesome because the sound of flowmasters is absolutely awesome but i have absolutely always loved the sound of the magnaflow systems...i am a college student and am on a relatively tight budget so the less expensive with the most performance gains would be perfect

 

id recommend edelbrock catback alot of people dont know much about this system b/c most people dont have it. i had it on my 97 3.8 before it got wrecked and i did see a noticeable amount of performance if you like the sound of flowmaster i think you'll like it. it is in my opinion a little more aggressive but not to the point of alot of raspiness. check this soundclip of an 85 T/A with the edelbrock http://www.youtube.com/watch?v=lNn4q4uyZpo. oh and the set for the v6 only cost me $299 but i think its a little more for the v8's
