Just changed the mufflers on my 340 Sport. The Summit turbos that came with the exhaust kit sounded OK from outside the car but had terrible drone inside. I went with Dynomax Super Turbos, 14" long on a 2 1/2 inch system. I also added an H pipe, using the Summit H-pipe kit. BTW, that kit is great if anyone wants to add an H-pipe. Here's the result at idle in the cold, humid air.
Sounds bad ***! I bet it growls amazing with the pedal down. Did the super turbos cure the drone that you had with the summit turbos? Do you have any wide open throttle videos for the super turbos? Also, where did you buy those muffler tips if you don't mind me asking?
