Will a header off of a 00 Si fit my 99 LS?

 

prety sure that it wont...

 

This guy is selling a greddy header off of a 00 Si at a descent price and I was thinking to pick it up for my ls.

 

i believe that the flange from the engine will bolt up correctly, but the length will be off so you might have to modify your exhaust piping

 

it will bolt up just fine but youre most likely going to have to modify the exhaust because of the length.

 

I'm going to be running a test pipe.

 

test pipes are usually made to be the same length as your stock cat

 

So I shouldn't risk getting it?

 

i used a b17 dc sport header on my ls,didnt mod anything i just pulled the cat to the header like 2in off,but it worked no problem

 

it won't b16 has a lower deck highet and the flang for the cat is different.

if it dont work sell it to me ill make it fit

 

I picked it up for $50 dollars and cleaned up so it looks like brand new with a guide that I found on TI. It also had barelly any scrappes on the bottom and there are no craks. I'm gonna try it hopefually sometime next week. If it doesnt work then I will know for next time. If it does but the flange is the problem I dont mind driving with open header till I figure something out.

 

i have an 2000 SI and had an 01 gSR i will tell u right now it won't be flush on the head, and you will have a nasty exhaust leak i know, cause i took my stock SI exhaust mainfold and tried to put it on my gsr and i had a big *** exhaust leak! so if you want to waste your time and money go for it

 

Thanks bro.
