ok. didnt know that. Thanks. And right now, i have no budget becasue i just learned about 2 hours ago that someone got my debit card info and overdrafted by checking account by like 120 bucks. so once that all gets straigened out ill see. But i had like 60 bucks. ill wait and save up for a better engine. it came with a .18. But do i heave to replace the exhaust system or will it still work? Ive never replaced an entire engine so i hae no idea what im doing.
