I just installed BBK Long Tubes with a BBK Cat. H-pipe on my 96 Cobra. At first I thought I had a exhaust leak. But I don't, I used Stage 8 Locking headers bolts on the headers. I got under the car and at the pass side cat. I can hear a knocking or rattling sound coming from the cat. I can tap on the cat and the sound would stop for a few seconds. I'm thinking that the stuff inside the cat is lose and rattling around in side there.
My Check engine light came on today. I thought that it only goes off if you have Off road pipe? I"ve drove the car with the headers for about 300 miles now and the light is just coming on? WHY?
How much HP and TQ am I losing from the stock catback?
The only other MODS I have is a C&L MAF with K&N and a Fluidyne RAD. I haven't made it to the the track or Dyno yet. What kind of times should I hope to get?
Thanks
