for 99 Integra LS...do they only have one size which i mean with a 2 inch collector to fit the stock cat? just wondering if i should upgrade to a different header. I got a DC ceramic 4-2-1 header right now.

BTW - i just got my RSR exmag installed and it sounds really good. I bought DC header, Comptech Midpipe, and RSR Exmag and got it all welded up at a local muffler shop. The midpipe was for a GSR so i had to shorten it. Long story short, for some reason the resonator on the comptech after cutting it shorter and welding it with the rest of the system hung very low. since i knew the ppl at the shop, they told me to drive around to see if it scrapes first and if it does i can take it back to put a straight pipe. i didnt know if no resonator would make it loud. but after driving it for two blocks, i went right back and took off the resonator and they welded up a straight pipe in its place. its still very quiet and sounds good. Im still running stock cat so yea. i'll take pics of the RSR exmag when i get a chance.

BTW if anyone is looking for a RSR exmag since i know its discountined, the muffler they're selling on the RSR website in the outlet section, is an axleback for a EG coupe, or 4 door integra....when i bought mine i thought i would have to make special piping to the muffler but that piece fit right in.
