thinking XEDE not worth it

[funkyman]

Aloha to you too
Exede does what a Comforti Shark injector does for 299. Except not being able to remove the rev limiter or the boost limiter
Sorry my other car is a 330CI

Its still too expensive for what it is.599 is an ideal price You would definately sell more and make more profits as opposed to selling a few at 1000usd.I would not install a crummy aftermarket exhaust,however a test pipe and down pipe yes, which by the way gives 40whp and at a cheaper price for 400usd shipped.So i rather not tamper with the ECU programmed in Hiroshima

I dont see how you can say its still expensive. You get a guaranteed min of 40 hp plus the ability to go higher as you add mods. YOURE in control!

Eventually youre going to have to free up the exhaust, so it doesnt really matter if you spend the additonal $1000 now or later. Its what seperates the boys from the men.

I look at the honda boys who spend thousands on their car for mods and their cars are still slow!

a good tune is always worth it if your trying to go FAST, if your not then u can be the car getting smaller and smaller in the rear view of someone elses' car

The ONLY gain in the exhaust system is to remove a stock CAT. The stock exhaust system is actually a very good part.

Stephanie, you said remove a stock cat. So, you mean get rid of just one of the two as opposed to a race/test pipe which takes them both out? If so, do you know if it would it also work well with the stock ECU and intercooler? I keep reading about different problems with race/test pipes and down pipes, some major, some minor. Be nice to have an uncomplicated, interim mod that adds some noticeable power before moving on to bigger, better, more powerful mods down the road.

 

[clos561]

isnt test pipe jsut a pipe that replaces the cat?

 

[StephanieT]

We have not replace the pipe yet. We will at some point, but for a power improver this part will be minor.

I would replace both CAT's to eliminate the restriction. Technically it is for "race applications" and will fail OBD II emissions testing. We have replaced stock CAT's on a MSM with a metallic core hi flow CAT for a 5 rwhp gain. Removing the CAT and replacing it with a straight pipe (on an MSM)yielded another 5 rwhp gain. For a total of 10 rwhp by removing the CAT.

But it is still a minor restriction. We placed gauges in the exhaust system to measure efficiency during several dyno runs.
Downpipe, Pre-Cat - 0 psi
Downpipe, between CAT's - 4.5 psi
Exhaust, pre muffler - 0.5 in vac
What was lost in the stock CAT was gained back in the exhaust. Overall, a fairly well designed piece. We will replace the exhaust with one of Corky's design. BUT, we are not expecting much of a gain if any at all.

DP replaces CAT1 and Race pipe CAT 2 and voila!!! 40HP WITH 400USD SHIPPED.

Is this all with the stock exhaust? If it is, then of course you are not going to get much out of it.

oh lmao, I forgot about those...

Is there a dyno for this, 40 hp for any exhaust seems a little optimisitic, or else alot of ms3's would be puting down 300whp with 40 hp gains from exhaust and 30 from cai's. Also, running a super loud exhaust in los angeles is pretty much a sure fire way to get pulled over and ticketed if you have any visable aftermarket parts on your car.

I agree until you start running a big turbo... 3inch is going to show some gains.

Whew! I'm so very thankful that I had an extra 1000.00 dollars to spend now rather than later...I dunno if I could live with my manhood being questioned by a well rounded thinker such as yourself.

It shows you who picks the money off the trees or their dads and who don`t,or earn it the hard way

there is a new dyno chart of a ms3 dyno'd with 4th gear pull put down 249 whp and 270something torque. TBE and intake could put these cars very very close to 300whp(five-0)

would a o2 simulator work with the mazdaspeed3? i know that ms3 has a four wire 02 sensor and i have a four wire o2 simulator and thought i would try to cut the wires and attach it to a pig tail from a new 02 sensor. what are your thoughts?

why would you want to put a simulator on your mazda3? splicing your wires sounds like something a spoiled 16yo would do. a neighbor of mine has a mazda 3 speed.and he took out the cats, put airshocks and jacked it up in the back. i was thinking you are that person. he's got a 4" downpipe w/no mufflers or cats straight from the turbo back. think he had to hammer in the firewall to fit the downpipe in. u from AL?

You mean like mine... But yet some still question it. It doesn't matter b/c once I get the standback, I am going to push this beast to 18psi. So the hell with it.
