It's awesome. 3" Test pipe, and 3" exhaust, with a magnaflow performance muffler. Ran me $400 installed including parts. Sounds a lot deeper but when just cruising I couldn't even notice it. Seems like turbo spools a little higher up in RPM range but it deffintaly has more go in the upper ranges.

if your only a k03 that might be a little bigg.. turbo might spool faster, but you will loose a little top end tq. but if you like it and it sounds good to you, nice!

At the moment no. Tax returns are coming in, so I'll be getting the FMIC, etc ordered. I just needed to schedule an open day and get it done since it had to stay there over night. I'm running the k03s right now. I'll be going to the GT28R in the next couple weeks.

Not really any complaints with it. I actually noticed better performance and sound of if with the 3" even with the k03s

Where the hell do you guys get custom systems done for $400 incl parts???? Is that mandrel bends? I can't find anyone in my area willing to touch my car for less than $800 or so. That's basically what I need, 3" from the turbo back to a resonator and then my OEM s4 muffler. WTF???!??!?! I can't find anything in my area.

Shop in town. He does really nice work. Showed me his wifes twin turbo 5.0 dual 3" exhaust. If you want I could have him make a clone of my exhaust and ship it out to you? Probally would be looking around $400 shipped? Without the muffler might even be cheaper?

Missed that. Yes its mandrel bent.

Only difference is I have t3 t4. does he put in O2 sensor bungs as well? Honestly, I may take you up on that offer. I wonder what shipping would be like could he make the tp and dp and the rest of the exhaust in a few pieces so It wouldn't be a nightmare to install?

Are you running a cat delete ATM? I don't know if he's going to be able to make a TP for a t3/t4, unless it was there. If you order a TP he could deffinatly make the rest of it I'm sure. The hardest part for him was fitting a 3" DP on mine. He said factory used a 2" pipe and it was crushed to get it to fit.

Girlfriend took some vids on my cell phone of the exhaust and some runs. They wont fucking send to my e-mail I keep getting an error on my phone. had some short 35-60 bursts, some reving, etc.

nice. you should of ran all 3" all the way back with no mufflers or nothing. just 3" pipes. its so loud. i done it and when i drove down the steet everyone was like "wtf is that" and they would look at me all crazy. good time.

when i got my get up done i got about one 1psi. i used two 3" core silencers and i love the sound.

yes, right now it's a straight 2.5" pipe from the turbo down (thats the TP portion) to the DP. it's all welded.

Sounds good. I'll ask him about it today and see what he says.


After my girlfriends off work I'll be gettin some video clips uploaded from her camera.

other way around. lose low end tq and gain top end power with increased flow.

yeah but miltek = $$$ then you still have to deal w/ the TP which is why alot of people go custom.

BTW how does the ebay FMIC work for you? I figure it's a cheap way to go. Seems like you can get the core for $100, and get the piping for another $100? If it works good I'll probally end up ordering that tonight. Did you have to do much cutting?

Labree Shotgun Testpipe + sourcing the exhaust system used = The Win... [up]
Car still isn't loud with the TP but it sure is stinky... [=(]

honestly, it works fine for me. My car's m.o. is cheap speed. in that regard it works fine. there are plenty other waaaaay better FMIC's out there I'm sure but mine does the job. The whole deal cost me about $400 or so but I was a bit noobish when I did it and I probably could do it for much cheaper now. I bought too much at once w/o measuring properly and spent too much but I'm sure it could be done for cheap. There was some cutting involved for sure, but not too much.

Car is in the body shop right now. The kit i ordered is shit. We decided to use the side skirts, and are pretty much fabbing up a custom body kit for it. I will get sound clips/videos up when it's done. This will now be with a GTRS, 3" inlet, and a test pipe so it will be a little different.
