My Agency Power Review
 

Hey guys, I just wanted to share my experience with installing the AP Headerback system on my personal/shop car. I've read the horror story threads and I know there's a bad reputation for them on this forum. My situation was unique so I decided to give my story.

I obtained an Agency Power Cat Back System from a customer for a crack head price because he had 2 exhausts. It was brand new in box and never installed. It was not my first choice for exhaust, but the price was right so I took it off his hands. After I bought it, I then read that long thread about terrible quality, bad customer service, etc. This didn't sit well with me, but I had already spent the money and I didn't want to sell it to a customer if it was going to suck. So I put it on my car. Fitment was a pain, the tips are very hard to get even due to the design of the exhaust. But once I got them even on both sides I was satisfied. I put an extra TBolt clamp on the joint that supposedly failed on the car in the bad thread. I honestly don't think it needed it but just to be safe, I did it anyway. The tone of the exhaust is great in my opinion. It's a little loud, but I don't mind that. The only thing I didn't like was the fact that the tips stuck out past the rear bumper more than other exhausts I had seen.
After 2 weeks of driving around with the exhaust I decided to order the Agency Power Front Pipe/Over Pipe Combo in an attempt to pull the exhaust closer to the bumper. I installed it 2 days ago and it worked! I guess the stock front pipe is longer, causing the cat back to be pushed back. As soon as I put the front pipe and over pipe in, the exhaust fell right into place. The sound obviously got a little louder, but so far it doesn't have that catless raspy sound, it still sounds throaty and deep.
In conclusion, I have put 200 hard miles on this exhaust and it hasn't given me a bit of trouble, it fits well and sounds great. It has a much different sound than most others I've heard, mainly due to the 2 small mufflers vs 1 big muffler design. I would recommend it to others, the only warning being that it is louder than Perrin/Nameless/Borla, and it has a slight in cabin drone. But the performance gains feel noticeable, I haven't dynoed or anything yet, it just feels stronger than before.

I don't work for Agency Power, I don't know anyone who does, I'm not even a direct vendor for them (I get their products through a dealer direct warehouse). I just want others to know that I have had success with it, so don't count it out completely due to the bad reputation.

Sorry for crappy iphone front facing camera videos.

Thanks for reading, if you're interested in this exhaust I recommend getting the headerback for proper fitment, just PM me!

Its been a hit with everyone that's heard it so far!

Honestly, it's the best sounding exhaust I've heard. Better sounding than my Perrin/Motiv headerback.

I thought about buying this system. I live in Phoenix and being that Vividracing is based out here it would be easy to walk in and pick one up. I have dealt with Vividracing for a long time and haven't had an issue with them.

By the way, I am kicking myself for not scooping that up...but I'm glad your car sounds so nice. It is a very well rounded sound. Thumbs up!

I'm trying to remember if I heard yours last Sat. I just can't do any drone at my advanced age. LOL

I turn 28 tomorrow, how old are you? Lol

I'm 33.

Happy b'day!

Happy Birthday motherfucker!

Happy birthday!

Happy bday

So bringing this back from the dead, I just picked up an AP cat-back locally used and installed it and it seems to fit nice be well made and sounds good. I haven't had it on long enough to decide yet but it may be a little louder than I want and I was thinking about trying to weld in the stock resonator in place of the AP resonator to tone it down just a little bit. Anyone try this or have any thoughts on it?

I realize this is really old. Just wondering if you accomplished this. I like that this exhaust is really light ~25lbs and free flowing. But I would most likely add in a longer resonator to keep the sound down even if it added a few lbs back in
