"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

"The product is sleeker than the original, and improves power and performance of vehicle which is much better than original. only thing lacking is a Need to have studs added for a heat shield or have a heat shield design for it. Other than that it is an outstanding product." posted by: yellowman on June 10, 2010
