Extra HP From Magnaflows
Anybody guess how many HP the cat-back Magnaflow system adds to an L98? The factory rating is 245 HP for my '90. Some people have asked me but I've not seen any information.

Re: Extra HP From Magnaflows (SteveBlack90)
Seems like all the mfgs claim 10-15 hp gain with the kit. I did not dyno mine before and after the Magnaflows, but question weather they added that much. The car made 305 RWHP and another LT-4 that day made 299 and he had B&B - other than that the mods were essentially the same from car to car.
Either way, I like the look and sound.
