okay, the tes headers for 90-92 dual cats is **** and doesnt ocme w/a ypipe. had i known this, i would have gotten the single cat and just converted over. anyway, the exhaust shop made a ****ty y pipe, its like bent every 3" to mold to my body underneath and is about 2 1/4 inches wide. this may be my problem with my mph. i have the dual cat headers so can i just order a y pipe from edelbrock and will it bolt on? will i lose power going from 2 cats to 1 cat? or should i get a nice built y pipe with 2 cats that is about 3".
