Cheers for the info danny. Ive recently had some cash spare and was looking towards a cobra catback, 3" decat downpipe, toyosport intercooler and remap but am looking at £1100 for the lot. £335 for the cobra doesnt bother me to much as they have very good ratings but the toyosport is near on £320 and would like it staged 2 remap £349ex vat at revo. Any ratings on building my owncooler from a ebay universal kit?
