I just purchased a Greddy evo2 for my 98 gsr and was wondering if i should go ahead and install the exhaust or wait till i buy my 4-1 DC headers, then put them both on at the same time. Also, my gsr isnt lowered, will installing 4-1 headers leave enough clearance if i drop the car 1in?

 

1. Your car has one header, not multiple
2. I would wait to do both header and exhaust at one time.
3. Any reason you are looking to get the dc header? Look into the jdm type r 4-1 header. can usually find a used one pretty cheap. Also can put a skid plate on it if you're lowered.

 

no im not stuck on DC...thats just what i was looking at. Wheres a good place to look for the type r 4-1?

 

I would just worry about speed bumps with a 4-1 header, they seem to sit pretty low. I would just install everything at once, that way you don't have to take them apart twice. I would PB-blast the nuts that fasten the header to the head now and do so at least once a week until you install the header. Trust me, you don't want to break a stud. Although this isn't a very common situation, it still happens. Also, buy new bolts and springs for the header-cat joint.

 

why would u have to take it apart twice?? unless u going to go with a header that wont bolt to stock cat, it makes no difference if u put on the exhaust first or the header....

Now if u are going with something that needs to be modded (meaning the header has a 2.5 in flang, longer piping, need a 2.5 cat) then i can see the point of doing it at the same time.

 

Ok well i was thinking of getting the type r header then i saw this. What do you guys think. http://www.peak-performance.net/content/view/56/71/?

 

I was just saying to take the whole exhaust out and install the header first, then install the exhaust. Makes things a lot easier to do everything at once.
