Hector put one, on my car last week. going in for the mufflers in the morning. He does great work and his prices cant be beat

 

What does this pipe buy you over stock?

 

here is the link to the pipe...

I'd rather go with a full catback, IMHO

this is the part that the greddy is missing right? Not bad 1000 bucks with that and greddy.. prob make like 5-6 whp all together.

 

Does anybody know about the diameter for the Greddy?, I ordered and I'm waiting for the Greddy to arrive, and then I saw this, I'm contacting Hector and he is telling that I may need to go with a 2.75" setup, but then he asked me to measure the Greddy pipes and flange, but I still don't have it and the website doesn't give specific information about it.

Any info will be great, thanks.

 

im pretty sure the greddy was 2.75. hector can make the y pipe in 2.75 to match up to the greddy. he was also talking about maybe doing a 3" for people who needed that application

 

Thanks for the reply. Well, that's what he is also thinking but I just want to be sure before I decide, I'm planning to install these myself, and I'm not great installing these things, so I just want to have both setup to match, so I don;t have any complications when I install them.

 

its a straight forward install. took us about 10 mins total all said an done

 

That's great to hear. I'm not a classic mod guy, my mods have always been little things, this will be by far the most major mods I will be doing to one of my car, I'm doing the Intake (I have done it before), and the exhaust and now thinking on the Y-Pipe, but one thing that worries me a little; I love the OEM sound, for me it's very distinctive, moderate and aggresive at the same time, I thought on that before ordering the exhaust and decided for the Greddys because of the silencer (Yeah, I know about how great it sound without them, but I'm not doing it).

So a couple of questions:

1-) What is your currect setup?
2-) How the Y-Pipe changed your sound or tone?, I'm worried about changing too much and then having a sound that I may not like, or even worse, too have the "drone" issue with my 5AT.

Thanks in advance.

 

1) I currently have the Greddy with another y-pipe (can't say which one yet), but the piping in the y-pipe is about 2.25 and goes into a 3 when it meets the mid-pipe.

2) After we put it on, it quited the exuast just a little bit. It sounds a lot smoother though when I rev, and feels much better. I have a 5AT as well, and 4th has a lot more now when you downshift from 5th. It also feels a lot smoother when accelerating.

 

^your y-pipe is probably $$$$$, haha.

Does Hector have plans to make any mid pipes?

lol yup, it's a bit more than double of what this one costs.

 

From what I hear Hector may also have plans for a full exhaust for the G37.

 

Thanks for that info, well, here it's the latest e-mail I received from Hector:

<<Everyone says the greddy is 2.75. What i was going to do was make the pipe 2.5". Where hte pipes merge i was going to make that pipe 2.75" because the greddy is 2.75". Worst case if the greddy is 2.5" the setup ill send will still bolt up to your system.>>
