MagnaFlow Tru-X pipe transitions are great for single/dual, dual/dual, and balanced tube applications. MagnaFlow's stainless steel Tru-X crossover pipes represent a significant leap forward in technology over traditional H-pipes. Their gentler radius allows for better exhaust gas scavenging, noise cancellation, and balance between cylinder banks. The results are a significant increase in power and torque but a reduction in dB sound levels--the best of both worlds.
