Ok i just need an answer very soon... right now i have full stock exaust on my 88se and I need a dynomax cat. which cat do i need cuz i know there are different sizes and whatnot. could someone just give me the exact part number. of course it needs to be one of the 3 way but there are different sizes and what not. So whats the part number?? anyone please???

 

dynomax utra flo stainless steel cat. it has a 3' in and 3' out. it is $180 from summit racing. go to the online cataloge for odering or part #. it is the best. I have a RB header and pre-silincer. with a custom mandrel bent 2.5" stainles pipe on my 88. the eco sniffers told me I needed a cat to pass emissions. so I got one of these and had a pipe made to replace the pre-silencer. there was no knowticable difference in the car vs the pre-silencer with the cat. other than the noise was less.

 

thats the one i was talking about in the pm you sent me bro, that the one i got, go for it........i just didnt know the part ##
good luck man

 

same here I got one from sumitt and had Midas weld on some flnges for 40.00 and made sure it was like 24 inches long it bolted right in and works perfect

 

do i want the 18 inch long one?
