I am looking to do soem exhaust upgrades to my 92 TBI, i have seen 2 diff items at edelbrock. they have a single cat I-pipe 2 1/2" i think and aother one. How do i know which one i have? and if I want a nice sound do I go w/ flowmaster instead?

 

I just replaced all my exhaust. I ordered all the parts from the block back and bought for a TPI car instead of TBI so I could get 3" intermediate pipe. The Y-pipe is a HUGE restriction in the exhaust.

** Added so far **
*GM Wonderbar
*Alston SFC's
*Turbo City Inj Spacer
*Dual Snorkel Air Filter
*March Performance Pulleys
*GM 3.42 Gears with OEM Zexel
*Edelbrock headers
*3" High Flow Cat
*3" Dynomax Exhaust
*Walbro 255 lph Fuel Pump

 

I order my cat back about a month ago. you'll need 2 1/2 (goes from 3 to 2 1/2 for cat only) to bolt up to the stock cat, that is what i did and am kicking myself in the @ss about it. I should have bought a 3 cat and 3 inch bolt up, but oh well I'll rig it when I put headers on.
