jdm 4-1 header scraping?

[steve]

if you purchase jdm 4-1 and still use your stock exhaust,
do you have to adjust the catback to accommodate the lower hanging of the 4-1 ?
or does the 4-1 hang low, then go up on an angle ?

i.e. is the 4-1 a straight bolt on to a stock catback ?

I had a custom catback which bolted onto the stock header, and when jdm 1 was fitted everything lined up fine.... HOWEVER the jdm header is designed to bolt onto a jdm cat therefore the flanges are different.

So u can also change to a jdm cat but then the cat back wont bolt up.

I ended up getting a flange made up using a laser cutter and modified the cat back to suit.
