Spectre Performance 22421 Stainless Slant Cut Review

As a result of my tests, I determined that this exhaust is a complete waste of money. The only pro is that it looks nice, but it does not improve your vehicle's performance. The con is that it is extremely loud and obnoxious, and it did not fit properly on my car. Overall, I would not recommend this product to anyone in need of a reliable and effective exhaust system.

Pleasantly surprised by the quality and price as other models I've seen in auto parts stores (for a bit more money) weren't as well made and finished.

is a great resonator. I built a straight pipe on my 2005 Yukon and it was very noisy. So I cut the end of the tube 12 inches and put this resonator on. It is designed for a large pipe like the Duramax, but will also fit a 3 inch pipe. Significantly reduced start-up and idle noise. Even full load noise is acceptable without reducing flow. Very nice.
