I plan on purchasing:

DC JDM 4-1 Header (http://www.inlinefour.com/dcsporjdm41h.html)
2.5" Carsound Cat (http://www.rollhard.com/rpcats.htm)
Apexi N1 Exhaust

Do I need to get the gasket or flange for the JDM header in the above website? Do I need the flange for the hi-flow cat too? Or should everything bolt right up?

Thanks!

 

What kind of car and motor?

 

the flanges from the cat to exhaust will bolt up if you are running a gsr integra the b pipe will have to be shortened you will need an exhaust donut too it is kind of a pain in the *** just for the header but you will be satisfied with the gain

95 GSR. Should I just go with a US DC 4-2-1 or a Comptech 4-2-1?

na , go with the JDM , i dont know about the dc sports bullshit, but the real JDM one is nice, I have already seen hp gains of 12whp from the header and test pipe combo

 

I plan on going the same route just a different exhaust. But in another forum it has a guy with pics of his mounted up on his Civic Hybrid. It hangs VERY low from the looks of it. Anyone with an integra running into lots of problems with this header. Cause i want a header and not a headache from all the problems it might cause.

 

i have a 00 Si with the N1 cat-back and i picked up a JDM DC 4-1 header yesterday and i still can't decide if i want a test pipe or leave the stock cat and have a muffler weld a piece of pipe to connect the two

 

the cat on that website is a universal cat so u will need to purchase the flanges and have them welded on. u will also need the donut gasket. however, what i suggest is buy the cat here: https://honda-tech.com/zerothread?id=226523 . smsp is having a g.b. on carsounds that are ready to bolt on and include the donut gasket.
