Im lookin at changin my 2 inch turbo muffler and manifolds setup for a new 2.5 inch set up with headers. Im thinkin of either goin with moroso spiral flows or single chamber flows . I really dont want 40 series flows cause every body has them and I want somethin a little different. Im just not sure how either will sound on a stock 400. The plan is to run it like this so its after the axle but still hidden. any of you guys have soundclips?

They'll probably be louder than FM 40 series and not sound good on a "stock" motor.....

thats what im thinkin but wasnt sure since ive never heard them on anything other then cammed motors. Now I did hear some spiral flows on a friends stock lt1, will my 400 sbc sound the same?
