corksport exhaust or TMIC, boost tubes, and denso spark plugs

[tunersteve]

I had seriously considered the Magnaflow for a while, but after looking into it, it just isn't worth it IMO. The piping isn't much larger, and the design requires the tips to be removed and new ones fitted in, not to mention many guys burning the valences on the back bumper from funky fitment.

IMHO i think one of the best design parts of our speed6's is that the exhaust is built into the bumper. I've been tossing around the idea of getting a single pipe but i just can't bring myself to do it, I want it to be dual and fit in the holes (butthump)

Same here. While it would be lighter and cheaper, it defeats a design element that was incorporated in the car from the start.

I should clarify...my system parts came off of a donor (totaled) car..

I had the shop use a 2.5 to 2.25 reducer on the outlet, in order to keep the trim ring and valance in place (and un-melted). Like many of you, I appreciate the effort that Mazda put into the look of the valance. Besides, at that point, there isn't any power advantage anyway. But, I intend on putting the second muffler back on, and just having a smoother y-transition fabbed up.

After driving it in this cold Tucson weather ( I think we hit 38 degrees last night) it just doesn't look right with one hole doing all the work, and the other doing nothing...WHOA, that sounds dirrrrty. (But I'm not putting the smilies here.)

That's what she said.

I agree. I would go to a single exit if it wasn't built into the bumper. I like the symmetry of the dual tip exhaust. Sounds like you have a little more unique setup that hopefully won't be an issue on the bumper in the future.

You honestly won't notice much with the tmic it's mostly for the big turbo upgrade.

Really? I thought it was one of the better mods for this car (without having actually done it myself). I was sort of holding that one back to be my "more serious" mod down the line, since I was under the impression that the intake and front end was the big bottleneck, and that the exhaust was relatively free flowing from the factory.

well since i did this after everything else.. maybe im not the guy to ask.. but, ive gotten some honest feedback from people who say this was a waste without the big turbo.. i think the stock tmic works just fine and is a waste without the BT.. but, i didnt do any real testing.. mostly it was noticeable on the freeway?? but dollars for donuts.. the test pipe and inlet do the most.. then exhaust and intake.. the tmic was just not noticeable (for the $$) in my opinion.. if you wanna see a small ass tmic check the new wrx.. its micro!!

Post 2nd-cat the exhaust is pretty free-flowing. Everything in front of the 2nd-cat is very restrictive. Open it up with a bigger, less-restrictive downpipe with a high-flow cat and you're talking big flow improvements.

As for the TMIC, I noticed drastically cooler boosted air temperatures post-installation. Additionally, it was not measured, but I experienced no more part and full-throttle studdering (believed to be knock) in the hotter months of the summer. I had previously run into a situation where during late June part and full-throttle shifts into third and fourth were invoking power loss. After the TMIC, this was alleviated.

One of the biggest shortfalls of our car is the inefficient TMIC. You can upgrade it to a more efficient (thicker, different style) core than stock, and keep the cost down, or you can go with the FMIC or LAIC for even better performance. It's not at all a bad suggestion for an upgrade.

Tunersteve i got the magnaflow had it since aug. I cut the tips off so I still look stock with the test pipe at idle most can't tell i have it. but from mid to high rang it opens up. also at low range let off the gas it has a nice deep louder tone as it slows down. Well i guess its perfect for me but not for most.

Interesting, that's cool that you kept the stock look. I wouldn't mind them fitting up right, but I don't want to risk damaging the bumper at all. I'm only running an SU test pipe and it opened up a little throatier note when you get on the gas.
