Question AA catless X-pipes or Challenge Race X-pipes?

Hi, I am ready to get x-pipes added to my AA rear section. Here in IN we don't have any emission test, so I think I will just go catless. Will get the AA ECU tune. Now deciding between AA catless X-pipes and Challenge Race X-pipes. any different in power gains? Both has two res, and Challenge Race is litter chipper than AA, also are there any different in sound?


any input is helping me~

Do a search for my thread. They are both dual resonated.. probably very similar sounds.

if the challenge one was only a little bit cheaper, i would go with aa. (to complete your whole aa setup e.g. rear and ecu)

I did lots of search, but no one compared the power gains side by side...

Fitment is by far superior on the Challenge piece.

I'm not too worried about the fitment, I think both of them is very good in terms of fitment.

All the x-pipes are pretty much the same in terms of sound and performance. The question is just whether it has cats and how many resonators, if any.

What about the Mastermind x pipe? Its cheaper then both and I like the 'X' part of their pipe. A true 'X' (aka, four pieces of pipe welded together) is supposed to scavenge better then two pipes that are cut down the middle then welded together

See Post #9 and #10. He wants to spend the extra money on a Challenge because it has been around longer. He does not seem to trust EAS's recent review and dyno test of the Mastermind:

Good choice I have their x pipe, cat exhaust, filter, pulley. Just got it tuned at their shop yesterday and let me tell you day and night . Car sounds very nice. Best part to me is no more cold start problems. I hated that. Now when I start her up in the mornings it's a smooth start. No more complaints from neighbors about my car. Had 3 complaints already. It's only loud when you get on it and it's a nice tone/exotic. I have no drone and you can definitely feel the extra hp

Forgot to mention my x pipe has their hfc's. I also have the straight pipes in my tool box for whenever I wanna go catless I can. Reason for doing cats is couldn't take the smell/fumes

you made the right move,AA,Challenge and Masterminds are great pieces but since you got the tune and axle back fro AA.IMO it would be right to have all there stuff.
