what ones should i get and should i just do the front ones or should i do all 4

 

Magnaflow 94106 from performance peddler or ebay. Use code clubgp or veedub whichever works for performance peddler. Remove all 4 old ones and replace with the two high flows. Place the rear O2 sensor about an inch behind the cat and you won't have any codes.

 

Yeah replace all 4. Get some 45 degree tubing and the high flows. Also some straight pipe to fill the gap because the high flows are much smaller than the stock ones. I am very happy with mine, got them off ebay for 60 apiece. ill post some pics of mine soon.

 

 

Just punch out your resonators.. it will be much louder and cheaper.

 

would these be smog legal?

 

Most hi flows aren't CARB compliant. I don't know if in Cali cutting out the back two would affect the tests or not. I know you guys have really touchy laws when it comes to that.

 

The 2 elbows don't do anything.. it's the front 2 cats that do. The 2 elbows are just resonators to reduce noise..

 

how does one do that?

 

I thought the resonators where the ones in the back and the ones doing all the work where the ones in the front
