I have a 1992 Cadillac STS. I have a special engine in it though. It is a 4.9L engine, but it has 32 valves. I have a Port and Polish done and I also have a performance cam in it. I recently bought a chip but I am having some problems so i sent it back and am awaiting my new chip. I am also looking into an exhaust system. For the exhaust i am getting 3" piping from the cat back to the muffler, which is going to be a Flowmaster, and 3" piping out and into my stock tips. I have it all set up with a mechanic and am getting it installed for just over $325. It runs 14.8 with the chip in and i want to dip it into the low 14s so i can rival the ever-so-popular LT1 engine, specfically with the Camaro Z28. Is there anything else that someone can recommend for other mod ideas?
