[/B][/B]Alright maybe this should be posted in the "Modification Review" section, but I wanted to share here first. After 7 months of waiting, I finally have my HKS Hi-power true dual exhaust for my 2004 Coupe (5AT). Current engine mods are Z-tube w/K&N filter, and plenum spacer.
First off, I don't have much experience in aftermarket exhaust, and I definitely don't have much experience with installing aftermarket stuff. But putting this thing on was easier than I thought. Well it's easy if you have a lift
It came with all the nuts, bolts, gaskets, and everything fit like a glove. I think the hardest part was taking out the stock pipes. If your going to do this yourself, goodluck. It's best to have 2 people because you really need to muscle those pipes off the rubber pieces (donuts?). Also, having some "PB Blaster" really helps to lube up the mounting points.
So the install took me a total of about 1.75 hours. 15 minutes trying find the lift points for this car. 15 minutes to carry in the HKS boxes and getting tools ready. 45 minutes trying to take off the stock exhaust
. 30 minutes to install the HKS exhaust system.
LOOKS - After it was on, I finally got to take it off the lift and get a good look at the rear...
....wow. This thing is gorgeous. I thought the pictures on the internet look good, but in person, Fuh-get about it! The stainless steel is immaculate and the welds look even better. The Quality and workmanship is very very nice. The angled cans and torched tips really sets the rear of this car off!
SOUNDS - After we dropped it to the ground, it was time to start it up. Again...
... It sounds perfect (to me). Obviously all this is a matter of preference, but I was looking for something that sounds deeper than stock (at all RPM's), and mean. At idle it sounds deeper and a bit louder. WOT it really sounds aggressive and throaty <is that a word?. Like it just want's to fight
I didn't want something that was high pitched or really loud and obnoxious. I also didn't want something that would wake the neighbors or set off car alarms. I just wanted something deeper, meaner, and louder than stock, and that's exactly what I got.
PERFORMANCE - This is where it got me a little
My butt dyno feels like I lost a tad of low end...not too much. Just enough for me to say, "Hey, what happened to that tad of low end". But I'm very very impressed with the top end (3.5k and up). It really tears it up. I guess it evens out. We took it for a little drive on a long straight road and opened it up, and again...
...wow. I can't speak for hard dyno proof...yet. All I have to rely on for now is the butt, and the butt dyno don't lie
So to sum it up. I am soooo happy with this exhaust system. I don't regret it at all! It scored very well in every category (well except low end TQ). But from what I gather, that's what happens with TD exhaust. Maybe it needs to settle into the car or maybe I need to reset my ECU. Either way, I feel I bought this exhaust mainly for looks and sounds, because there's no exhaust that will put out high amounts of gain on this engine. If your looking for performance output, save for forced induction.
I'll say it again...Pricey. Yes.
Worth it. Ya DAAAAAAAAM RIGHT!
I have pics but I'll have to load them later. I also have a 3MB sound clip if someone can host it.
