Clean up the Hi-Power.
I can't speak on behalf of the AP, but I loved everything about the Hi-Power when I had it on the tC a couple years back. I've heard great things about the Agency Power too, but I prefer the simple polished canister on the HKS.

^Thing I like about the Agency Power is the adjustable hanger on the muffler, that way you can set it just right under the bumper. To raise the muffler push the muffler hanger/clamp towards the front of the car; to lower the muffler, push the hanger/clamp to the rear of the car. I've had mine for almost 4 years now, only issue I have is the muffler spinning on the piping. The muffler on this system isn't welded on, more like slipped on but "snaps" to it's spot. Def will set off alarms with this exhaust alone, if you have a header you'll probably have to either add an extra resonator or ditch the header. Now you have the whole cat-back Agency Power setup correct? Post back once installed and go for a drive.

Well I loved the hks well still like it but what I noticed its heavy compared to the AP. Now I have a question should I run it with the Megan midpipe? Or with the agency midpipe?

AP was by far my favorite exhaust and i had 4 diff setups. Its the best sounding exhaust on a N/A tC imo.

So far I have had like 4 as well started off with no brand axleback + stock mid then added no brand midpipe then went to a tsudo with the no brand mid then got the Megan mid with the tsudo axleback then got the hks with the Megan mid and now ima see how this goes with the AP axleback and Megan midpipe for a bit then switch it out.

So far the HKS with the Megan midpipe has sounded the best and has had the best fitment.

If you want to compare weight just the axle back alone I think Agency Power is likely the lightest out of all. I almost dropped it picking it up because the muffler weighs nothing, titanium ftw. Some don't like the burnt look of the muffler though. I might have to check gaskets also as on start up I've noticed a bit of rasp, but once everything is warmed up sounds like it should. I've been thinking of trying my TRD axle-back with the AP mid just for kicks, and that'll also pinpoint what could be causing the bit of rasp on start up.

Irishguy: lol the axleback or midpipe?

Dropzone: yeah man it's super light I was like wtf haha. Yeah so far I've been super lucky not to get pulled over with any of the exhaust I've have (knock on wood) haha but then again I don't drive stupid most of the time. Just hope this isn't a cop magnet haha. Yeah you should check the gaskets mine were all burnt and split in half.

So threw it on this morning and I have a leak because of the gasket here is a vid
Agency axleback and Megan midpipe

No revving since I have the leak

Well here's some revving, and some driving by, this was when if first had it on my 07 tC, only mod that car ever had

http://s18.photobucket.com/albums/b1...rrent=tcAP.mp4 if it asks for a pass, try the screenname backwards. Also sounds much better on actual computer speakers, car speakers, anything that's not your cell phone speaker lol.

something to consider is also your ride height, at the angle the AP sits, puts the canister lower then the hks. at my height, my canister scrapes and sparks on the highway on dips and such.

i still love my AP!

When I lowered the car more, I scraped the canister going through a dip on a bumpy road and has a slight flat spot from it risk you take being low.
