1 CAT vs. 2 CATs
1 CAT vs. 2 CATs
I have a question about the 89-92 Dual Cat cars. Okay, on my 88 IROC-Z the exhaust looked like this...
{} {}
{} {} Headers
{} {}
\\ //
\\ // Y-Pipe
||
[ ]
[ ] Cat
||
||
||
||
[ ]
[ ] Muffler
[ ]
|| ||
|| || Outlets
Sorry about the sloppy drawing
Could someone please "draw" the Dual Cat system...
-Thanks

I won't attempt to improve on your art work, but there are actually pipes from each header to each cat, and both cats are located on the passenger side.
Otherwise, that's the idea.
