"This converter appears to be well built, and solved my P0240 (inefficient catalytic converter) code problem immediately. Can't beat the price and free, quick (3 days) shipping. If your existing front pipe is in good shape, this converter is well worth the hassle of adapting it to fit." posted by: Pistole on September 11, 2010 view all 4 reviews
