Hi all, been reading this site for a long time and finally got myself an FD about 2 months ago.

Was completely stock 67k's when i got her from Japan (now in NZ)

As i said, been reading this site for a while and never had the need to ask a question as i could always search, but i came across something i couldnt find... someone will probably make me look like an idiot with 5 different links but anyway...

My question, are there any differences in the Y-Pipes of a series 6 and 7?

My FD is a series 7 and has a flange type connector for the IC pipe, but the IC kit i recently bought, which was advertised as fitting 92-97, has a silicone joiner type thing.

Talked to a wrecker and he can supply a y-pipe with a coupler type connection, but what else will i be looking at? any advantage with my current one?

Hopefully i have explained myself well..

On a side note, has anyone heard from Flyrx7 lately...sent him a few emails about the speaker pods but he hasnt updated his website for a while...

Thanks in advance

 

The y-pipe with the flange is much better than the older style with the coupler. The older coupler style y-pipes tend to get boost leaks. What intercooler kit did you buy? Pictures of the kit and part in question would be helpful.

 

The flanged/bolted style is better streamlined and helps increase boost a bit. It also is less prone to leaks.

If you compare the two, you'll notice the "flanged" all-metal design that your car came with removed the bung (for the hose leading to the blow-off valve) from the internal air stream....allowing better flow. MAZDA claimed some hp increase, but it was probably the result of a number of design changes they made that year and not just the Y pipe. Still, better flow, together with removing the leak prone coupler, your "flanged" design is better and should connect to any otherwise suitable IC the same.

 

So, would removing the Y-Pipe and cutting the flange off, then getting some grooves machined be a better option than replacing it with an older style y-pipe?

 

If you could post up a picture of exactly what your dealing with, and the type of IC kit your referring to, it might be easier to make suggestions.

 

If you trully 100% need the older style y-pipe, I'll be happy to trade you mine for yours

Post a picture of your intercooler kit and the part in question from the kit. We can help you make a better decision based on the pictures.
