We got a box today. I opened it up and fell in love with the contents. In fact, the contents were so nice that I busted out the tripod, hung a sheet from the ceiling, aimed some lights and actually made a real effort to take nice pictures.

Let me say that again - Clint actually tried to take some nice pics. This is not normal, but neither is the Grimmspeed up-pipe.

Here's the write-up on them:

We here at TiC see a lot of parts. A LOT of parts. In fact, we've become kind of jaded in the type of stuff we see since there's a baseline of quality and performance in a part that's needed before we carry it. Every once in a while, not too often, but every so often we run across a part that so far exceeds what we expect out of a quality part that we just sit back and say "WHOA!"

The Grimmspeed up-pipe is one of the those parts. I have confess, I'm having a hard time writing this description because I just can't express in words how blown away I am with this part. Seriously, this blows away ANY other up-pipe we have seen. Period. Bar none. End of story.

Let me break down what we want in an ideal up-pipe and then fill you in on the details.

• A part that fits like it was meant to go there from the factory.
• Thick flanges - thick ones stay flatter longer
• A flex section - we have found that this is actually rather important
• The flex section down low on the pipe - this allows flow to smooth out a bit before entering the turbo. A flex section at the top is just dumb
• Smooth bends spread out over as long a distance as possible
• Consistent inside diameter to smooth flow
• A nice transition from flange to tube

Now, here's what's on the Grimmspeed unit

• Beautiful fit
• Nice flat flanges that are over 11mm thick (stock pipe has 10mm thick)
• A beautiful flex section that has a nice big ID to it doesn't constrict the tube size. Oh, and it's down really low.
• Bends that are so smooth and take up almost the entire upper section of the pipe
• Beautiful transition into the bends due to using a mandrel to shape the tube
• Transition from flange to tube. THIS part of the Grimmspeed pipe is... well, is just overwhelmingly awe inspiring. Here's what they did - they counterbored into the flange for the tube. That means no step from flange to tube. Incredible

.

Oh, and there's one more thing. The welds. Artwork. I'm gonna hire their welder to just run some beads in random patterns on a plate of stainless steel so I can hang it on my wall as art. I'm serious. I'll send you pics once I have it made. These welds are in-flippin-credible.

*Grimmspeed up-pipe comes with 5 nice new studs to use with your, superior to everyone else, up-pipe.

Now for my pics. Maybe not the best photos you've ever seen, but I guarantee the best you've ever seen from Clint.

very nice, what's the ID compared to stock?

[twiSTies]

very nice.

how well would this pipe mate to a GT Spec manifold?

I'm trying to remember, but isn't the GT Spec one of the large bore setups with their own UP?

Let me get back to you on that. It's dinner time.

Answers:

Grimmspeed - just over 49mm on the inlet side. Just over 45 on the outlet side.

Stock - just over 42mm at the wide part, not the crushed part from the crappy bend. That's even smaller.

Sexy piece.

Will you ship to Malaysia? And will this work with stock JDM twin scrolls? Thanks so much.

This will not at all, even one single little bit, work with JDM twinscrolls.

First off, have you taken the heat shields off the JDM twinscroll UP? Not much to change there since it's fully tubular and bent smoothly. about the only thing you can do to improve the JDM header and twinscroll design is grind the welding flash at the flanges smooth.

Second off, this is a single scroll UP. There's only one tube. Twin scroll requires two.

Ooo.. thanks much.

Is there a chance these will be available with an external wastegate? I'd love to see P&L use this for there setup.
