exhaust and more
I was wondering that if you had a performance exhaust N/A would a downpipe and header make it louder? deeper? or change the sound in any way?
what about removing the cat? I figure that would make it louder but may not be good for a N/A car because of the lose in back pressure resulting in less power also where can I find heatshields for S13, one for the intake mainly is what I'm looking for I found this exhaust www.rs-r.com/exmag_gt2.htm and it has 80 mm piping for 89-94 240sx, is that too big for a N/A would I need more like a 60mm for a N/A?

80mm is for turbo.60mm would be about right for NA

yea, you need 60 or 65 mm for n/a, 80mm is for turbo
header makes your car sound a lil more like a honda, and a lil louder there is some loss of backpressure with no cat, and loss of torqe. your best bet is to get a high flow catalytic convertor. the apexi n1 catback creates backpressure itself due to the dual piping... that's good for n/a your best bet for the heatshield would be to call your local nissan dealer.

Adding a header to the KA does not make it sound "more like a honda" Quite the opposite in my experience... I even drove mine open header during my exhaust install. I had to drive to the autoparts store, after I installed the header, but before i replaced the remainder of the exhaust... It makes the exhaust note deeper due to the larger than stock piping the exhuast gases are now reverberating through.

she said she had a leak in the EGR valve that was welded during the swap.And in the entry before that she says she's prolly the only one with a sr20det driving around with a stock muffler.
