Benefits of midpipe
 
When I get my car back I was looking to install a midpipe because I heard it saved the cats from wearing down(aka not using them at all lol). I just got the car inspected so I dont need to get it again til 2012. Any other benefits? Or crucial differences?

Catless midpipe, performance.

dshiznit1489 10-29-2010 12:47 AM

Better flow for the engine. Probably a 5-8hp gain in HP, sound difference, weight reduction, FLAMES.

BuBuBDunk 10-29-2010 12:49 AM

Haha. Which can I get with a stock exhaust?

WAR CRUNK 10-29-2010 12:54 AM

i have been rockin my midpipe for a few years, And the ebst part is, MY 8 burns so well, that i pass inspecion with streight pipes!!! the computer cant even pick up on it.

Pretty sure most will fit with stock exhaust.

RIWWP 10-29-2010 06:41 AM

Get the BHR one though. The rest are just wasting your money. Sure, feel free to spend $100, $250 or something on another midpipe, it will develop the rasp (faster the cheaper you pay), and it will get on your nerves.

Start with the BHR midpipe right up front. No rasp, no packing to burn, fantastic fitment, wonderful sound, nice extra kick in the pants.

paimon.soror 10-29-2010 06:55 AM

+1 for BHR (with davesport if you cant clear CEL)

BuBuBDunk 10-30-2010 12:46 AM

I will be getting one when I get my tax return most likely. Should I get the davesport cat too?

The answer to that lies within you. :smoker:


Do you own a Prius?

YES,,, Put a cat on it.
NO,,,Don't put a cat on it.



I'm just sayin' :dunno:

9krpmrx8 10-30-2010 09:07 AM

:lol: +1 for BHR midpipe. It's not hype and I'm not a fanboi. The BHR pipe is my third and last midpipe.

GeorgiaBII 10-30-2010 01:41 PM

Does running a mid pipe make the console any cooler?

RIWWP 10-30-2010 05:15 PM

I haven't measured it, but probably. Heat doesn't get trapped in that location of the exhaust any more. Still some heat, but not nearly as much.

What about the CEL. my 8 is up for inspection and in texas we dont have the sniffer but they just plug in the OBII port. Im thinking i can just unplug the battery before i go in but it really cant be that easy.

Marklar 10-30-2010 05:41 PM

You'll likely get a small performance boost, but not much.

Main benefits are more noise and FIRE :) Rev, REV, throttle lift, kaboom, FLAME!

No this will not work. There are a series of "flags" that must be set to OK by the PCM before the ready flag will trigger for emissions checking. If that flag isn't checked you will fail the emissions test.

It usually takes 2 to 3 drive cycles for these flags to get checked as there is a whole host of criteria the computer must complete. Unplugging your battery will prompt you to fail the test.

Tweek 10-30-2010 06:26 PM

i like my B&B :D

Red_Fox 10-30-2010 06:36 PM

^^+1

GeorgiaBII 10-30-2010 06:59 PM

Can the CEL be turned off without buying a access port? I may have to do emissions in a few years :(

Then install the cat, get it e-checked, reinstall the midpipe... thats what I do.

Do you think the few of us running Midpipes but don't have a CEL would pass ? I wonder what they can check while plugged into the OB II Port? It would be interesting to have my 8 pass that test but stink up the waiting line because I was running a midpipe. The inspector might go nuts wondering how such a smelly car can pass. I have the RB dual resonated pipe which could pass a visual inspection to most people not familiar with it.

Red Rex 10-30-2010 07:20 PM

I like my Agency Power. Has a little rasp but nothing ridiculous like some people made it out to be. Car feels faster from the mid-range and up and its dual resonated so its almost as quiet as stock. Weighs about half as much as the cat too.

CyberPitz 10-30-2010 09:02 PM

I've always wanted to get a midpipe, but scared due to legal reasons. Everything I can find points to Joplin, MO not requiring an emissions check...but dunno.

Suggestions? :)

Move to Arkansas, they don't do vehicle inspections of any kind here, let alone emissions tests :)

I think you mean consent, conception is another story. And it's only 16 if the other person is under 20, you perv :P

makristal 10-30-2010 09:49 PM

You can delete the CEL by using like a spark plug spacer or a Spark Plug Non-Fouler. You just really have to make sure it fits appropriately.

Red Rex 10-31-2010 07:25 AM

I've had my Agency Power on for a couple weeks now and still no CEL. I've got my trusty AccessPORT though just in case.

I used to have an Agency Power Mid-pipe as well. I had no CEL on it what-so-ever. I currently have a CEL on my Racing Beat Mid-pipe though.

hornbm 11-01-2010 05:45 PM

Any negative thoughts on the Racing Beat dual resonated mid pipe? Everybody seems to be a fan of the BHR one, but racing beats products are typically top notch.

makristal 11-01-2010 06:36 PM

Did anyone notice a lack in fuel economy with the Agency Power midpipe? Or is it just me revving the shit out of it which is making the fuel go down? I feel like I'm driving the same as always, but am noticing a difference in the fuel consumption.

The problem is that every midpipe other than BHR is a piston engine'ed midpipe design in a package that fits our cars. The BHR one is the only one designed for rotaries, and the heat we put through our midpipes. Other midpipes simply can't hold up to it. Even Racing Beat's get very raspy and buzzy. They just take longer than other brands, due to their better quality.

BlackRX82006 11-01-2010 06:55 PM

The ONLY benefit of a midpipe..IS DA FLAAAAYYYMEZ

Razz1 11-01-2010 09:37 PM

You can get the benefit of getting the car towed on site as you are a FELON.

No benefit unless you race on a track.

BlackRX82006 11-01-2010 09:58 PM

Yeah, you FELON!

uncleant 11-14-2010 08:20 PM

Right now i'm running a turbo xs with their mid pipe but buying a bhr midpipe with davesport cat. Will i really be able to notice the difference in power between the two?

Not likely, I have had three on my car and the BHR is the best in build quality and sound but I didn't "feel" a difference in power. I will be on the dyno soon on and off nitrous and we will see what I pull and then I will let you know if there is a power gain off nitrous.

tony.colombo 11-14-2010 11:40 PM

I just installed my racing beat mid pipe last week and no CEL sounds good noticeable difference in power. Especially reaction when shifting the revs do not drop as low pops right back up. only downfall is sound car is wicked loud now

racing beat header , mid pipe , greddy SE exhaust

fun killer

pdxhak 12-28-2010 01:48 AM

Last time I went through DEQ my O2 sensor was bad. I just unplugged the room fuse to clear the CEL before leaving to get checked. It worked :)

PaPaBear 12-28-2010 07:27 AM

Does installing a mid-pipe effect the factory warranty. Bougnt my 2008 40th anniversary new over a year ago and still under factory warranty.

Chris 12-28-2010 08:14 AM

Just keep your stock cat pipe on hand for when you need warranty work

terch1 12-28-2010 10:31 AM

I went with a highflow cat because I didn't want to deal with a cel (no cobb yet). Anyways I love it.
