Okay so I'm currently running the stock exhaust with res delete and pops and bangs added in on a stage 1 map... but I want more. More noise, more pops and bangs, yup I want to be anti social when I put my foot down. Question is do I go full catback exhaust system or decat downpipe and therefore stage 2? Is there going to be much difference in cost? If I go new exhaust system I want it valves and resonated which adds a lot of cost, and I want one that doesn't sound raspy. If I go decat downpipe I'd get more pops and bangs but how goes this sound with the stock system and res delete?
