Since my friends gave me back some money i lent them awhile ago, im deciding wether or not to get some headers. I am looking for a really deep pitched sound to add from my flowmasters. It sounds deep as it is but i would like it to sound even meaner, engine wise i got a 5.7L 350. I am a semi noob when it comes cars ( i know a little bit) but i was wondering if your imputs could help me decide which headers to get as i dont know which ones blow and which ones are good.

Thanks
