I have heard that my 08 LS came with the lsj header but I havent heard about the downpipe. Could I still benefit from an SS downpipe or is that on my car also? Thanks

 

From my understanding its the LE5 intake mani...not sure about the exhaust manifold though.

 

u WILL benefit from it ,nice cheap upgrade

end of thread :p

 

the lsj exhaust manifold and dp are different than the ls/lt, yes you could benefit from the lsj dp cause its about twice as big as the one you have right now and it only has one cat when yours has 2 alot of people prefer to go aftermarket though so its your call

 

sounds good, just wanted to make sure that I wasn't replacing something that I already had. thanks

 

no the manifold was the same but the dp on the ss is way bigger than the ls one

 

I thought that was the case, you are talking about the exhaust manifold right?

 

the manifolds are different from what i ve heard the runners are bigger on the lsj and the bends are smoother theres pics that show the differences

 

The main point is that either way I will benefit from the ss downpipe then, that is what I wanted to clear up. Thanks guys

 

my LS only had one Cat.
people think they have 2 cats, ones a resonator. and even mine didnt have that.

 

mine has 2 cats

 

than u will benefit more from the lsj downpiipe, the second cat is not neccessary

 

i know, in order to get an ss dp for mine i have to cut it and extend it
