I'm looking at getting shorty headers for my car in the near future. Are there any opinions on which to get? I looked at some from DNA Motoring for $90 (https://m.sears.com/dna-motoring-for-ford-mustang-4.0l-245-v6/p-SPM4029152621), but would like it if someone has personal experience they would be willing to share, as the price makes me skeptical.
