okay so i just bought some RB exhaust from another member today

My question is whether to just cut the mufflers down to size to fit my Y pipe i have on now so that way i can still put my stock ones or my cheapy N1 copies back on if i wanted...



Or just get a new Y pipe made to complete my FULL RB exhaust set up?? also that way i dont have to modify the mufflers and keep them the way they are



i know these mufflers were to be used with the full RB set up but i basically bought everything separate.. so i have the RB na headers and presilencer hooked up to my stock Y pipe and now a set of old school RB exhaust mufflers..

here they are after i polished them up =]

compared to stock




thanks in advance

 

I love those old RB mufflers, I would not modify them- I would have your stock exhaust modified to fit them

 

while your at it, paint em for that added mental note that they are clean when you put them on. I cant imagine this being much benefit without new piping.

 

Buy a racing beat y pipe. Then it will all bolt up. If that isn't an option you can get a custom one made. Ymmv with the quality of the Y split though.

Racing Beat Y-Pipe for all 1986-92 RX-7 Applications
Part Number: 16447
Retail Price: $225.00

That is straight from Racing Beat

 

The stock Y pipe isn't split all that bad really. The problem with it is how it is welded together (nasty like) not to mention it splits a 2.5 pipe into 2, 2 inch pipes.

 

Like every one ealse said just buy the rest of it so it bolts up easy.

 

I dont know if the new system components will bolt up to the old mufflers, and they may be turbo mufflers and his car is NA

 

damn at the moment i dont have or want to spend another $225 on a RB y pipe.. i might just go ahead and get on made to complete the system...

and ill look into it getting cleaned up and painted thanks for the tip

and yup i think he said these are turbo mufflers


thanks ya'll, made my decision making a little easier

 

they are turbo mufflers and your car is obviously NA, so even if the new Y-pipe would fit those mufflers, which I am 99% sure they wont, it would still need to be modified.

At that point you might as well just have a local exhaust shop make something up for you

 

+1...I have the old RB exhaust on my N/A (y-pipe and mufflers) and it still didnt bolt right up. There was the difference in pipe diameter and like a 3 inch gap between the pre-silencer and Y-pipe. So either way you're going to have an exhaust shop fab something up for you.

 

^ forsure thanks for the info man
