Hello
Do you want noise? Or just bit more power.
Heres a few options. Ring me asap as I am coming over this weekend and can bring some cheap.
Firstly Paul @ South Coast Performance can fit no problem very good. OR slightly cheaper is the ATS garage at the end of Pulrose Road.
What car do you have?
Magnex Decat with Downpipe - £350 approx Nice box. Louder than standard, more power. Subtle.
HKS Hyper Decat - £600+ One of the best flowing systems on the market. VERY VERY loud. Excellent performance. I have this one at the mo until i get my own system on.
CustomScoobies TFL system - Full Stainless decat with titanium tip (Will be on an island car this weekend). As good system as HKS yet cheaper. £500
CustomScoobies TFL Twin System - Same design as the TFL Single system, but twin tailpipes. HUGE! Looks the doggies danglers. Will soon be fitted to my test car. £525 +vat
Amongst others.
All depends what you want then mate. The 2 I designed are excellent if I do say so myself
