It seems MBRP is the only one that comes off the pipe. All others come out of the chamber and all have a shorter nipple or almost no nipple at all. I'm thinking this is the issue. If it runs fine with my stock can I'm ditching the MBRP and gonna try something else.Hps is right in the chamber
All I know is I experimented with cans last year... and maxwell can vouche....If you pick the wrong one.... It will sound ....and run like an airplane running out of gas.
Ya they do. Could be why it makes the sled run like crap
