If i get the catted x-pipe from slp will i have to buy a 02 extension or anything in order for it to work or will i just bold it on and it will be good to go

i know for both of my cars i dodnt need them, both 03s but im not sure if gts are the same. i know the mach1 and terminators the 03 didnt need them but the 04s did

and also if you havnt already ordered it look for an x pipe with cats that arent round, mine scrap on everything b/c they hang low and im not even lowered yet

 

well i have the lm1 with a off road x only not the whole cat back and yes u will have to get the 02 extensions...well i have to not yet got them but will and ur check engine light will be on the whole time if not on...also probaly be running leen the first 3 days.... gas will suck those 3 days bro

 

i didn't need them with mine....

 

only 04 model years needed them for some reason, so no you shouldn't need em. I have an 02 GT and didn't need extentions for my X

 

Huh?

If you have the o/r x, of course you need them. This guy is asking if they're needed WITH aftermarket cats.

"...well i have to not yet got them..." Is that English??

Leen????? Without cats and without O2 sensors, you will run RICH, not lean, which will hurt gas mileage. Lean would actually save gas, but could do engine damage.

Why would it just do it for the first 3 days? What am I missing here?


Sorry, just got annoyed I guess.

 

exactly what he said, only the 04's need 02 extensions. you'll be fine, should bolt right up w/ no problems

 

I have 03 gt, slp x and lm1, and the only issue I had was the driver side flange didn't fit snug on the stock exhaust manifold...leaks a tad bit. just a little taptaptaptaptap....

 

yes only 04 cars need the extentions

i bought mine used from someone local, and im pretty sure my cats are not round. it is a older pipe, maybe 2-3 years old. it was on a garage queen tho so it was almost new when i put it on.


also im not sure the new ones come with the race pipes you can swap in place of the cats, the guy hadthem when i bought it from him
