a few of the mr2 NA guys have ran pacesetters for 1+ years, fully wrapped, with zero problems what-so-ever... they didnt even reinforce the welds. people used pacesetter/hotshot back to back and reported unnoticeable performance changes... the best manifold for the 2.2's over there was a custom "shorty" style one-off header.
btw, pacesetters can be bought coated.. i believe part of the reason pacesetters are so cheap is because: 1)they're uncoated. 2)pacesetter as a company is HUGE, its not like they're a specialty shop. buying steel in bulk saves them tons and tons, so their profit margin can still be high with low priced products.
pacesetters have 2.5in collectors... whats your hotshot have again?
wrap has been proven to help reduce heat and keep up velocity. theres really no arguing that. it would be like saying the world is flat. btw, you can purchase wrap just about anywhere, its relitively cheap too (20 bucks to cover a header roughly).
