So i live in sacramento California. Here we have to pass smog every year in order to keep a lisense. Well i think i am going to go ahead and do the test pipe newayz, i just cant resist those great gains for so little money. I am thinking every year when smog tests come around i will just throw the stock cat in or in the future i will buy a hfc.

 

lol yea that will work man, but i think a better Idea is to have a custom cat done down lower in the exhaust where its easier to change out, have a straight threw cat welded to some 3 bolt flanges and just have a piece of straight pipe go there when you dont want the cat

 

yeah thats probly a good idea but i just ordered that borla from purems. **** o well i will make do with wut i have. is it pretty hard to get way under there and put the test pipe on? or should i do it from the top.

 

Bah everybody ive talked to says testpipe is a bitch. I'd assume youd have to go under for sure.

 

you have to go under to get ethe back part of the exhaust off and then the DP which is a bitch then from the top both sides of the cat

 

ahh i think i may actually end up waiting till i can afford a hfc. what are the gains like w/ one of those?

 

not as much as with a TP

 

Good, not as good as a test pipe, but still good. Much easier to install too.

 

how do you figure its easier????? you have to do the exact same steps to get everything apart and back in

 

Because you dont have to deal with the different diameters of a tp. Just what ive read from people who have done both.
