ya but if you do that ull get a CEL no?
cuz ure right, that's a much cheaper way to go


Wow, a magnaflow high flow cat is quite cheap actually, would this fit?

cuz on the magnaflow website, there's only a direct replacement for the 2.2's, not 2.4's or 2.0's

 

bump for info on the cat

plus I really need to know if gutting the catalitic converter can throw CEL's (there's an O2 sensor after it no??)

 

i just got the LSJ dp and its bigger

that cat will work i have that same one.. you will get a CEL tho most likely .. just leave the stock cat if your that worried

/thread

 

what do u mean? u actually installed that exact same cat on your LSJ dp?
how does it feel on a 2.4?

thanks about the quick reply on the cat gutting, that's what i thought also...

 

no i have that same cat on my OBX dp.. im going with the stock lsj because you cannot tune my car yet (long story) and when i can tune my car i will get another header and still use the lsj

the cat is really nice and it tucks just about anywhere you wanna put it Pre o2 or post o2 but for sure the lsj dp is staying on my car ... i want to get the jbp header but not till spring

but like i said earlier if anybody is worried about CEL's there just a thing that comes with modding cars and if you dont want them then dont mod your car haha or suffer the consequences

 

okay thanks

 

picked up my LSJ dp for $35 bucks btw

 

nice! how many miles on it?

 

where are u guys getting the DP for so cheap

are there any gains, if thoes numbers are true they are 1/4 inch bigger

 

bought if off a friend 20k on the dp.. you can get them cheap idk what ppl are thinking asking over 100 lmao it cracks me up

 

Im selling a catless 2.5" downpipe off of my ss/sc for a hundred bucks. even has the bung welded for a wideband o2 sensor

 

maybe wed listen to your post if you didnt sell your GMPP header and your hood for *** dollars... thats right i have to censor that price because its so low!! lol jk bro good luck with the sale of your remaining items

 

lol thanks

 

The lsj downpipe is 2.75" o.d. and necks down to 2.50" right before the catback. The neck down is only about 2-3" long. I had the CTI 3" downpipe, and really didn't feel much of a difference between my stock lsj downpipe and the CTI downpipe.

 

Update:

LSJ DP pipe diameter is 2 3/4"
LE5 Auto DP pipe diameter is 2"
L61 DP is 1 3/4"

LSJ DP on bottom, LE5 Auto DP is on top. The LSJ DP does not easily fit onto an auto LE5!

Thank you for showing the 2 downpipes together. So many people on here argue and fight that the 2.4 SS/NA has the same size downpipe as the SS/SC. I agree with your measurments of the lsj downpipe, because I just measured mine last night
