But i found some on ebay that say up to 600 hp for $900. that would save me some money, wouldn’t have to buy 5 bolt downpipes. Doubt anyone on here would trust those lol. But damn even with the 530s which are the cheapest after everything else i need it’s just above 4k & that’s a lot for me. Hmmmmm. i just need to send it money can be made back. i have 2.5 piping & ic’s but i’m used to driving a 2000 2.0vw golf so 450 range on 91 would be plenty for a long time.
