The 'goose is best VFM and is British built too :!: It's stainless from turbo to tip, and the 5" looks the mutts nuts. Yeah, it is loud, but on the motorway cruising off boost/ on slight boost it's plenty bearable, and as long as you've got a decent headunit and speakers, you'll be fine :!:
Apparently the Peco is based on the std system and as a consequence is quite restrictive. The HKS systems are mild steel ( Paying £400 for something that'll last a couple of years on our roads ... :?: )
Y'pays y'money and makes y'choice, but IMO - go 4 the 'goose :twisted:
