...to go with my brand spanking new RS*R frontpipe I got when I was in Japan. The cat back needs to be at least 3" I.D. all the way through. Most descriptions I see on web sites usually say that a pipe will start at 65mm then go to it's advertised size. Does anybody here know firsthand of any styles (I don't care which brand) that never go under 3". I know I could take one into a muffler shop and have them cut off the truncated inlet side and weld on a larger diameter pipe and matching flange, but that seems like work. :p Much thanks in advance.

I know a guy selling the power extreme that has a 3" inlet from the Y-pipe.

 

just what is a cat back ,and how does it relate to headers,cat. convertor and mufflers. thanx

 

Its exactly how it sounds, "cat-back." Its everything from the catalytic converter back, including muffler(s).

 

to be honest i don't think there are ANY catbacks available here that are 3 inch internal diameter all the way thru. (for the FC anyway) i'm pretty sure the GReddy extreme that was mentioned above still starts at 2.5 inches. the largest one that i knew of here was the APEXI GT single catback. this one starts at 2.5 and flares to 3.4

 

Well I asked how big the inlet was from the Y-pipe and he said 3". The reason I had asked him was because he was selling the PE catback off a TII & wanted to know if it would bolt on an NA.

 

I forgot to mention that I just want a single pipe exiting either side. I was going to get the Apex'i GT until I found out that it was tapered down at the inlet. I think I'll just get this 80mm setup that's hanging from the ceiling in the shop I bought my frontpipe. It tapers down so I guess I'll have to take it to a muffler shop for them to do the welding. The hard part is getting my buddy to buy it and ship it to me from Japan. Oh well.
