AA catless Xpipe vs any other catless Xpipe?

Rekrul · 01-31-2012, 09:28 AM

I know the AA is dual resonated. Doesn't seem to get much love on here, how does it compare to other catless Xpipes? Namely Gintani?

I like the way the AA pipe has V-Band clamps for the primary cat delete. You can make or buy primary cat inserts if you later decide you want the cat option for inspection purposes.

You could add this to other catless x-pipes, but more work is involved since the V-Band clamp is not in place and the other makers do not offer the cat insert pipe option. It would be a DIY job.

Hmm... interesting. I guess that is kind of nice, though I'll probably just leave my stock piper in my garage. I'm just trying to figure out how loud it really is.. compared to others. Is the challenge dual? Fabspeed?

Quads sound better and drone less.

Gintani or borla quads are nice.

We've installed a few Challenge/Akra combos here in the shop - been very happy with fitment and sound.

The Akrapovic X-pipe would my choice since you already have the SlipOn system. If within a particular budget, the Challenge Race X-Pipe (stainless) would be a close second.

Is the challenge dual or quad resonated? Thank you for your input!

Challenge is dual resonated.

M3DCTBT · 02-01-2012, 09:49 AM

not impressed with any challenge x pipe as far as power. Akra has no drone, all other exhausts seem too. Start there.

I have the slip on. Looking to pick up an xpipe. What are your impressions of the AA xpipe in terms of power?

Have you checked out Fabspeed's x-pipe yet?

Merked M3 · 02-01-2012, 01:42 PM

Do the resonators restrict power in any way? Or is it so minimal it doesnt even matter?

Because i wonder what a dyno would say on a Challenge race vs race+

The Gintani is a good piece, had it on the car for 2 years, fit is perfect, certainly increased volume but did not add any drone. Made the car sound mean. Downsides are the smell, but you get used to it, and when running it hard on the track, having to clean the rear of the car, with AW it would turn beige. With, SG, it shouldn't be too bad.

rjd598 · 02-01-2012, 02:08 PM

+1 on gintani

Have not tried it. I have the Gintani Dual, I liked it a lot.

persian54 · 02-01-2012, 03:58 PM

I had an AA Xpipe with stock rear

now i Have a full akra

I would say, pick up an akra xpipe

I believe EAS should have the Akra in stock

I'm cheap. Id prefer to buy second hand xpipes lol... otherwise I'd do this as I have the slip on.

I just instaled AA catless x pipe today and i must say the sound is amazing, that of course is my opinion and its a subjective one. It sounds stock unless stepped on hard which then produces an exotic ferrari/rasp type of note, not very raspy but just right for me. I do get this weird small noise, like a humming at certain spots on the rpm range. It sounds like when you wind your finger tip over a glass just a lot deeper. This doesn't happen throughout a rpm range just on a given rpm, mine is at 3900. I'm very picky and paranoid about noises so im sure most people wont notice, i also have the rear stock exhaust so that may complicate the sound, im sure with a full exhust this would sound just great.
