Hi guys. just looking for a little help/advice have an rs250cup and booked in for mapping in a few weeks mods so far are AEM air filter (open cone type) 3" decat/downpipe mid box delete airtec intercooler have added black series engine mount insert and vibratechnics dogbone mount while I was at it and plan on swapping out the plugs for a mini service of fluids etc before but anything else worth adding? will the standard exhaust excluding the downpipe and mid box chop be ok? just don't want that to be a massive holdback when mapping tia
