New Exhaust for Mazdaspeed Proteges

I was kind of mad looking just at the peak #'s but if you look at 6500rpm I gained about 30 horsepower at the wheels. The car doesn't fall on its face anymore in the upper rpm's.
 
Forgot to mention that I did tape the dyno runs today. Hopefully I can get them on the computer in the next couple of days and someone can host them for me.

Its close, but not close enough to melt the rear skirt ( I could fit my finger in between). Also some times it hits it, but its only once in awhile. Hazes dynos weren't that bad. Im thinking of getting CustomMSP smic next. What do you guys think?
Why don't you consider getting a fmic so tha you can ugrade your radiator if you want to?

IMO a fmic is just overkill at this point, i still have a lot of work to do until it would really benfit the car

How much bigger is the core on a smic than it is on the stock one then?

Do you guys have more clearance than this? I put the kartboys on the front of the car, but if I were to put them on the back section it'd put the muffler in my bumper. I think I got the bad exhaust out of the bunch ;\

I had the same problem. I could only use three of them. The very rear one made the tip sit way too close. I used a different hanger in that spot and it works fine. Probably just a combination of slight variations in the car and in the exhaust, no big deal. The Kartboys in the front should keep you from clunking. You could always heat up the actual hangers rods and bend them a little, if you really want to use all four.

here is a link for a comparison thread on the SMICs that are avaialable for our car:

and guys I had no problems with my kartboy hangers, I have a lot of room between my bumper and the tip, i'll snap a picture later, so as dirtysouth said it must be little differences in the cars and exhaust.

LOL, I would not go back to that shop if I were you, joefufu. The "special" wires come with the exhaust, along with instructions. I did it myself. It was pretty much just like extending speaker wire or something like that. Just follow the instructions carefully or find a shop that is willing to read instructions. Also, make sure you or whoever you get to do it, insulates the fcuk out of the connectors and the extension.

EDIT: LOL, you must have been posting while I was writing. You need a good set of wire strippers, a good set of crimpers, and some good insulating materiel. I may have gone overboard, but I used Heatshrink Tubing, then electrical tape, then cold shrink tape.

Haze20 & RenzoMSP. I used new kartboy hangers and I have no clunk at all. However, I could not use the kartboy on the very back, near the bumper. It made the tip of the exhaust sit way too close to the rear bumper. I was kinda afraid that it would melt the rear piece of the body kit. I actually got a hanger from a local exhaust shop that's a little longer and it works great. Probably could have just used one of the stock hangers but I just cut the stock ones off.

Lol.? O2 sensors use shielded wires...which are kinda hard to come by. Probably why the shop said they couldn't do it...
 
Yeah, so now do you have more or the same clearance than me? I might try throwing the third KB on there, but I think it'll raise it up too high. Even with the KBs I still have a little bit of clunk up front. I might get some washers to move the xmember down a little.

Yeah, I understand what you are saying and that there could be potential problems, but it can be done. None of us are having any problems yet and hopefully we won't. I guess the LOL was a little inappropriate, but oh well. I guess that the shop did not want to do anything that might cause him problems down the road. (dunno)

I think that I may have a little more than that. But, I did not use the stock hanger in the very back. The one I used, I got at a local exhaust shop. It is a little longer than the kartboyand the stock, so it makes the bumper sit a little lower.
 
any new news from our vibrant exhaust enthusiasts? anybodys exhaust really open up yet and break in?
 
I opened it up the other night after doing the dyno pulls to see if I could feel a difference. Just like the sheets show its pulls alot stronger especially above 5000rpm. That where I saw the 30hp gain.
