Grimmspeed Downpipe

In case anyone hasn't seen pictures of these beauties yet... This is the catless/coated/limited version.

BTW, when I picked this thing up from the shop Matt mentioned there may be fitment issues with the divider tabs mating up to VF40 turbos. Not sure on the VF46. Understandably, applications with these turbos are not their primary target market. He sent me a few pictures of a simple fix that I'll post later. I won't be installing this thing for another month or so. Has anyone installed theirs yet?

Lookin' good. Mine's the same one, but catted, and not here yet. I will be pairing it with a VF48 that's going out for port and polish work on the WG and coating from SoCal porting before installation. I'll mate the two up together and check clearances on the divider plate. That was a concern I had, but it's easy enough to remedy if need be.

I'm pretty sure a big batch of coated pipes went out on Monday so I'd expect it to be to you fairly soon. Let me know what you find. I may just take this as a sign to upgrade the turbo...

What's different about the "limited" one?

Limited adds:

I can confirm there is a fitment issue with the stock TD04 VF40 turbos. I was the one who discovered it and talked/sent pics to Grimmspeed and thats the fix they came up with. If you dont you risk overboosting because the divider rubs on the wast gate causing it to stick and make an annoying rattle. I ended up just getting a 18G turbo, so did not have to bend the divider, but if I had kept my VF40 I would have.

i have absolutely no need for that pipe... yet... i still want one.

That's pretty pretty

I missed the GB by 2 days was looking at the Catted version a great price given its made right here in the USA. I like the flange specs not sure if the limited perks are any more helpful that not but still the piece is nice. Looking a DP option for my 09 LGT Right now Invidia and Turbo XS are front runners but If i can buy something made in America ill go that IF it is of quality

Bummer! Mine hasn't shipped yet, and should next week (backup in the coating dept). Then I'm selling my TXS DP

I've been really happy and had zero issues with the TXS. In preparation for Stage 3, I was going to have a bung added and have it coated, but that would have meant some downtime for the car. That was my only justification for the new GS one since it had those options, and I can't resist their product line.

I have pretty much no need for such a pipe either but it is a tasty looking setup. Noticed this one a few weeks back. Still on the fence if I'll go this far or stay with my current setup. Curious what the mod is since I'm on a VF40 with a 16G wheel.

I'm using the fitment issue as a justification to throw on a VF52, so don't feel too bad

BTW, here are the pictures GS sent to me. Looks like the tab just needs to be bent in slightly to avoid contact with the wastegate. I'm still slighty curious if this is an issue with the VF46 as well. I'd imagine it is. Can't hurt to swipe a VF52 anyway!

Only td04 housings are effected.

<--- noob

Based on your response, I take it the VF46 does not use a TD04 housing and therefore will not require modification to the DP?
