what about hybrid TP/HFC all in one?

^
those are for people that are really **** for getting the perfect sound.

 

Stillen HFC's and HKS exhaust right now, with about 2k on 'em. Car's going in the shop next week for cams, head work, and Tomei headers and TP's, plus a few other things. No issues with the Stillen's.

 

Berk HFC. Constant cell reset with osiris almost weekly. Berk sent me wool and washers for free and cell hasn't been on since. A little raspy with turboxs exhaust. HFC got 7.6whp 6.29wtq and then another 5.36whp 3.82wtq with uprev tune which was done last. OEM intakes. Total 285.93whp 257.40wtq all on same dynojet. About $2200 spent for 12.96whp and 10.11wtq = waste of $.

 

So wait, you're saying you spent $2200 on high flow cats and a tune?

 

If I must...
$500 turboxs exhaust installed
$500 berk hfc shipped
$901.00 osiris and cipher w/cable and tune
+ Dyno before and after each with the shop labor for install. Cost $243 for HFC install and dyno before and after. Can't find other receipt for exhaust but I think it was $60.
Total = $2204 which was a serious waste of $

 

If it makes you feel better, I'm going to be in the same boat. I just bought Berk TP's and I have HKS exhaust with the Stillen Gen 1 intakes (short ram) then I'm going to go to Technosquare and get a tune. We'll see how this goes.

1200 for exhaust, 300 for test pipes, 400 for intake, 550 for tune =$2400, not including installation. Then I just bought Quaife LSD and 4.08FD for $2,000 more so total is now $4400. Not including install. (waiting on adam from z1 to ship them)

 

I have Berk TP's sitting in my garage right now. Ordered my HKS through THM like 3 days ago and thought they had 1 left but they didnt, now I gotta wait for the next shipment to come in

 

I have AAM test pipes matched up to HKS Ti exhaust. Never threw a CEL, and just had my inspection done. Test pipes coming off next month--Greddy TT going in.

 

I have the fast intentions resonated test pipes in stainless steel which look awesome. They are mated to a power-intense y and greddy single exhaust. I had them for about 7k and my cel turned on. But its because there is a small leak and the guy forgot to put that red selicone. Im going to tune it once I come back and just have it turned off...but here is a vid of my car..sounds killer...

Can anyone explain further?

 

I'm hoping to get my HKS + Berk TP combo before you! Let's make it a race. I have my TP's but I'm waiting for some parts to come in so I can get it all installed at the same time.

 

^ My HKS is already on order through THM and they're suppose to overnight it to me once it comes in But you still may get yours before me haha.

 

well the name "hybrid test pipe hfc" is kind of misleading.

it's actually a pipe that has a resonator on it, and also a metallic core, so basically a resonated high flow cat. I think the combination of both restrictions makes it pointless and you might as well stick with stock cats.

 

That was my thoughts as well. Glad someone mentioned it.
Thanks.

 

A perforated core resonator isn't very restrictive. Depending on the quality of the HFC core, it's should most definitely have a higher flow rate than OEM DE cats, and probably higher than OEM HR cats. Coincidentally, perforated core resonators flow pretty well, but suck at dB reduction.

 

I have Turbo XS test pipes on mine with the Top Speed Pro mufflers and let me tell you.. it sounds insane.

I feel like like I lost some torque down low but I can definitely feel a good power gain midrange around 3000 rpms though.

Definitely worth it in my book.

 

My berk test pipes came in today. This time I did the install myself. I am off from school so I thought I should save some labor money.

Removal of my berk hfc's was pretty smooth (the bolts were not as tight as I was expecting). The passenger side I got access to all bolts from under the car. But the driver side the top left bolt I could not get from underneath b/c the steering column was preventing me from properly putting my ratchet on the bolt. So I had to go through engine bay. Fortunately I got a good position on the bolt after removing driver side intake tubing (otherwise I may have had to unbolt the steering column, and I am no mechanic so that was a big deal to me).

First off I wanna say that test pipe noise is overrated. I was afraid I might get this horrible loud drone when cruising, but it turned out that it was just as loud as the berk hfc's, which is no problem to me. Second, there is this annoying raspy sound I get when I rev to 2500rpm, but I think I am getting used to it. It does make me cringe every time I hear it though. Also, the sound is louder at WOT, but this is a good thing b/c I think it sounds sick.

 

I had berk HFC... than they cracked at the bracket... so... AAM test pipes.

so much win with the sound.

Can anyone help me source the cat flanges (3 bolt)? Looking to build something custom
