I was asked by a former customer to bring back the Mongoose Packages like we did on the C5. When looking at muffler options for sound and power I could not find find anything on the flowmaster system. Our c5 Mongooses ran either B&B or Flowmaster I decided to try flow master on the C7 Our goal was all bolts on no head modifying no camshaft Making a reasonable price Mongoose C7 560 We were at 460 RWHP with the stock non NPP muffler we need to be above 465 with a 17% loss thru the drivetrain on an auto Adding the flowmaster we got 479.3 RWHP and 500 FT Lbs RWTQ Flowmaster added 19.3 RWHP & 24RWTQ
No drone just a nice sound when you step into it. Welcome Back the Mongoose with the Mongoose C7 560 100 HP at crank. Seems to be in line with other catbacks out there I will try and figure out how to post the dyno sheet later Ron
