Need some advice for next mods

When I fix my mid-pipe, I'll take a video of my exhaust. I run header-back with no cats. It's not that loud, you just have to do it right.
 
Nice lookin wheels. I have no cats as well, it is very loud, but I also have an exhaust leak, so we'll see how it sounds once I get that fixed. I'll be at the bbq too, so you can try out a number of different sounds.
 
alright i have a plan. im going to order the obx header from ken(protegegarage). im trying to find a dyno place around here, so i can see how much i acheive with the header and typhoon cai together. i'll dyno my car with the mazdaspeed axelback and typhoon cai, and then i'll get it dynoed with the obx header. im thinking i'll get 114whp out of those 3 mods. it might be more because i dont think my car is at 103whp right now, im thinking it's at like 108whpish with just the mazdaspeed axelback, so i might be closer to 120whp, but i'll try to find a dyno sometime this weekend. if anyone knows where a good dyno place is in ga send me a pm.

An axelback won't add 5hp... I'd be surprised if you were above 110... but there's a TON of factors that go into dyno results, keep in mind. Humidity, temperature, octane, (blah)

Good luck though I'm interested in the results!

lol, yeah i know, im probably like at 105ish. im thinking i probably gain 1 to 3whp out of it. i will find out when i find a dyno though.
 
I wouldn't disregard your claim at all...I have been refered to as a ricer in past by some friends...but I assure you, you can gain a little hp from sound...

I know that sounds ridiculous...but exhaust resonance has a lot to do with pulse pressure...stock mufflers are tuned for keeping resonance supressed...so it doesn't annoy you, your girlfriend, or your neighbors...and by freeing up resonance by means of only a muffler (no screwing with diameter, etc.) you can pick up small gains...Some mufflers such as the one incorporated into the RB cat-back (don't use this example extremely, that thing does have a .375" bigger ID, which makes big brunt of its gains) have baffles that are not much more "free flowing" than that of the stock one...mufflers such as that really only make the exhaust louder, because of the arrangment of its baffles...yet they do not do much for flow...and yet you can still gain a couple hp...this does not apply to most straight cut canister things...they usually do nothing on there own other make your car sound like a sh*tbox...and hurt pulse flow overall...

its all in scavaging and resonance...so the ricer adage that "louder is stronger" isn't entirely untrue...just a lot less true than what they say it is...
 
install i see what your saying. my main reason for buying the mazda sport exhaust is for the exhaust note. i dont really care if i gained 1whp. i just like the exhaust note of it. i'll just do the dyno because alot of people want to know what are the dyno numbers for the header. so im doing to the dyno for those people that want to know the whp gain of the header. i've made my mind up into keeping the exhaust and just getting the header. i'll like thank everyone for the feedbacks though.
 
ebay has an obx header for the protege, and it's 30 bucks cheaper coming out to 210 including shipping, if you are trying to save some money
 
here's some k&n typhoon cai pics. sorry about the bad quality of them, but it was taken with my cell cam.

full exhaust. keep the axle back and just get in front of it done and save some money. spend the rest on the sways or save for a standalone ecu like the microtech turfburn is selling
 
Man you're nuts. I LOVE the sound of my MazdaSpeed. It droned a bit on the freeway, but nothing a little turn of the volume know can't fix.

Earplugs should be sold to go with that Mzdspd Axleback.

I did have some top speed gains on it though when I had it.

i love my mazdaspeed axleback, and it's not that loud from the inside of the car. it can be loud when it's passing you, but you get a nice, deep, and non ricey sound from it. if anything i'll just get the piping from the axelback to the header done custom. the cai sounds nice though. i can get to 100mph alot easier now, and the psst sound when your shifting between gears.
 
When do you think you are going to get the dyno numbers? I am curious to see what kind of gains you show. Keep us informed.
