i was wondering if the racing beat y-pipe and and both mufflers will bolt up to my stock 87 n/a pre cats and header, also if i just bought the y-pipe and mufflers and hooked them up to the stock exhaust piping will that pass emissions testing?

 

Yes it hooks up to the stock front end.

it will definately pass a "visual" emissons test and should pass a sniffer test. Ther are less restrictive than stock.. but if you leave the cats on, the engine operating parameters sould still be within specs to pass emissions. (opening up the exhaust on N/A's tends to make them run rich at FWO, but should not really affect the emissions under testing conditions)

 

My first FC had that set up and passed the test.

 

thanks guys
