hey guys, rite now i have a 3 inch espiler catback exhuast system on my 240sx coupe 93. i will be doing a RB20det swap and im wondering will be be bolt on like it would with the SR or would i have to get a custom down pipe?

 

How are you going to mount the RB?

 

why a RB20?

 

well supposedly mounting the RB shouldnt be too hard since its an RB20. all i would need is the custom mounts and it shouldnt be a hassle. but im still wondering if my catback exhaust will fit it the way it is rite now...and for Ayuaddict, im going RB just becuase im trying to save a few bucks also of the fact that its something different. too many SR's out there although i wouldnt mind having one. and of course, the DAM WIFE is a ***** about everything so what can you say?..nah mean?

 

Well the reason I asked about the mounts is I know with some mount kits you have to purchase a certain downpipe.

 

i know a few people with rb20s... they reused their exhs after swapping. not sure what mounts. I would take an rb20 over a redtop any day

 

i was asking only because the RB25 dosent cost too much more than a Rb20...

 

Reviving this thread so I don't have to clog up the boards with another thread, anyone know any vendors that sell 3" catback systems for the S13? I'm in the same situation as the OP pretty much except I just need to buy a 3" catback system. Links would help a ton, thanks guys.

Always appreciated....thanks

 

so an exhaust bought for a ka would bolt up to an sr20 if one was swapped in later on? Curious because my 240 doesnt have a muffler but I plan to do the famous redtop swap in a year or so

 

*infamous

just pickin ka/sr/rb all exhs are chassis specific

 

ah good to know! Cause not having a muffler is keeping me from driving the car....(along w/ the timing being off and a slowly dying tranny lol)

 

thanks why everyone shoudl move to Michigan.. you dont need exhaust!!

my friends got a 91 supra, stops at theend of the turbo outlet lol... soudns liek a semi truck.. its a beast

 

can we get a vid of that supra? and what does it mean when an exhaust is chassis specific? just specific to that vehicle type? feel free to flame, im learning.
