If you have a near stockish system with a 2.5 intlet, you don't want a 3" outlet Y hitting it.

So you have a choice here. Run is "as-is", buy a 3" Y back system or mod it to fit.

I bought an used Borla and hacked the mid-muffler and added a Magnaflow resonated X pipe.

 

whats the difference between the one u posted and this one which i have seen a few 35-z nismos have this similar style.

^^^^
read the whole thread...



hint..

diameter

 

Im for this y pipe, since the design we know works. But what I don't like about it, is the diameter size.

 

even for the guys that run the HKS axle-back, buy this and just have a muffler shop make you a cheap middy. bam, full cat-back setup!!!

 

lol i thought the first one posted was 2.25 also.. nvm

 

well, it's an option and it's out there for you guys. def sweet for V36 guys since a lot of the full cat-back setups for you guys are like $1,500+. now you can piece together a full setup for much less.

 

so, just to make sure, what is the coupe midpipe ID? 2.5" or so?

 

But wait...if the inlets to the cheaper priced Y pipe you posted are the same as stock HR-Y pipe (2.25), wouldn't it be a better choice since its closer to the stock HR-Y pipe size of 2.25 inlet/2.5 outlet?

The outlets for both pipes in this thread are both 3" which seems to be the only issue which again can be corrected if need be.

I really don't see the problem between them honestly. Its not like we're talking about loosing major whp or wtq response.

Non of us has run a dyno between all three Y pipes (Original Z HR -Ypipe, the one from page one and the ebay one posted by socialconflicts) to really see the difference also.

How bad can it be?

 

well I bit the bullet and bought it, got tired of lokking for an hr pipe, i just got the megan y back that i just bought and i will let you know how it is... it should be here by friday

 

sweet, keep us updated, thanks...

 

I'm a noob when it comes to G's. Do these open up the exhaust well with a stock catback? I assume those are high flow cats on the pipe to stay emissions legal. So what would this do in terms of sound/power with the rest of the exhaust stock? Thanks for the help, and link.

 

they're flex joints not HFC...

 

Damn. Do this deletes the cats? So it wont pass emissions huh.

 

^what makes you think this y-pipe would delete the cats...?
