Evolution X – AMS Twin Tip Exhaust (First Impressions)

I have to admit.  I purchased my AMS exhaust a couple months ago.  Needless to say real life distracted me and prevented me from getting around to taking it out of the box and putting it on.  I purchased the Twin Tip Exhaust, High-Flow Cat, & Down Pipe w/ O2 Eliminator.

Here’s a link for people who are interested!

Well anyway, last week I finally got around to installing everything but the Down Pipe w/ O2 Eliminator.  A friend of mine was kind enough to let me use his garage and tools, and even offer me a hand. It was pretty sweet, I didn’t feel rushed to get the job done before the rain came, and he had a really nice camera to help take pictures.  (I’ll include them at the bottom, so if you’re tired of reading skip on down!)

I have to say taking off my stock parts was a LOT harder than putting this on.  This thing went on so easily, didn’t cause me any issues.  However, taking off the stock cat from the down pipe.. now that was much harder than it needed to be.  It’s definitely a leverage issue being on ramps and probably won’t give you any problems at all if you can get the car up high enough.

So anyway, so far I’ve tried out two of the restrictor plates to give my exhaust note a different sound.  There’s a total of four included with the exhaust, I’ll get around to trying those out as well I’m sure.  It literally takes 2 minutes to swap them out.   You just have to make sure you tighten down the bolts or they will rattle if you leave them loose in there!

There is a couple negatives though.

First, my mid-pipe came with a dent in it.  Not sure if it came from AMS this way or happened in shipping.  I find it hard to believe it happened in shipping because the packaging was really good.  We made sure to take pictures so I could show AMS.  I don’t think it’s going to affect performance, but the rest of the exhaust is so damn beautiful it really stands out!

Secondly, the High-Flow Cat is throwing a SEL light.  Now I understand there is a spacer you can buy to take care of this issue, and AMS even has one.  The issue here is I bought a FULL Exhaust.  DP, HFC, & Tips.  I’d think thought that it would come with everything, including the spacer.  They obviously know it’s a problem so why not just send the part along and save the customer the hassle.

But let’s not end on a negative note.  I spoke with AMS about this and they understand where I’m coming from.  They have great customer service and do actually listen.  Just make sure when you order yours you get that spacer!

Overall I am extremely pleased with the system.  As I said I haven’t gotten the down pipe in yet, but that’s going to happen next weekend.  I plan to also take some sound clips so stay tuned for those hopefully this weekend.  But for now here are the pictures!

    Hey Chris,

    Won’t your high flow cat fail visual inspection in NC, even if you get the spacer so the SEL is off? How long did it take? Worth it to switch back and forth around inspection time?

    I think I’m going to be okay come inspection time. 🙂 I’m not to worried about having to switch back and forth either. But if I do, it’s super easy to switch would probably take me less than an hour. Total time it took to install once all my original parts were off was MAYBE an hour. The parts coming off took more time just because of the leverage issues. Now that I know how to do it I could probably handle everything in under an hour. Definitely worth switching back and forth if you have too!

    So how does it sound? I’m thinking about pulling the trigger on this one. How loud is it on idle and how about cruising at freeway speeds? Have you put the different restrictor plates in? How much of a difference do those make if so?
