Hey guys,
I need some advice on what to do with my exhaust. Ive got a 91 RS with a 305 TBI/auto. Its got Edelbrock TES Headers & a Flowmaster Cat-Back. The car sounds GREAT... Most of the time. My problem is the catalitic converter.
The converter on the car is the stock one. I know that its shot because the car has over 120,000miles on it & I am failing emissions. Also, the cat has a leak in it that sounds like POOP!! At certian RPM's, usually when the car shifts into drive or overdrive during light throttle, you can REALLY hear it. It sounds like a loud ticking sound. Anyway, I already bought a 3" Magnaflow Cat from E-Bay. Unfortunately, I bought a 3" cat were the pipe that it needs to be welded to is only 2-1/2" These are my options:
Return the 3" cat, get a 2.5" cat
Just use adaptors to make the 3" cat work
Return the 3" cat have have the exhaust shop do a custom y-pipe with dual cats.
I dont want the exhaust to get any quieter. Which is why I am worried about using adaptors. I have heard that using them will sometimes create a muffler effect.
