The power gains from stage 1 to stage 2 are lame and not worth the cost, nor the hassle involved with the downpipe. That's from an APR stage 2 customer.I saw this as well. To be perfectly honest I never really understood the appeal of APR Stage 2, because the power gains seemed insignificant next to the incredible wear and tear on the clutch for manual cars. The whole downpipe business is sad to me, but I feel like Stage 1 or an IS38 tune should meet the needs of most.
However, how do the slight gains from going to stage 2 equate with "the incredible wear and tear on the clutch" ?
