OK, I'm going to sell the HFP, which has served me well, but I now have a decision to make. My guess is that all of the axle backs I'm considering will have about the same performance gains, so it really is just a matter of style and price.

Which would you get? Also, will all of these bolt right up to the stock b-pipe?

Based on research from these boards, it seems that if I go with the spoon or fujitsobo, I can upgrade with a spoon b-pipe later for more gains, which leads me more towards those two. Will the HKS or RSR also bolt up to the spoon b-pipe?

They are all quite pricey for an axle back, with the RSR and Wagolis costing more than the Mugen Twin Loop for my EM1 (back in 2002). But the HKS can be had for a steal in comparison.

Thanks for your opinions.

 

if the rs*r bolts up to the stock b-pipe then it should bolt up to the spoon no problem, I currently have the spoon N1 and love it, but I really love the look of the rs* axle back

 

I like HKS because their hi power sound is deep and beefy on fit. there is a sound clip somewhere.

 

If you eventually want to get an upgraded B-pipe, then why bother with just an axle-back?

From experience on my car I went from a Fujitsubo Wagolis which was really nice and looked great to a Fujitsubo Power Getter, which is just a little bit louder than the Wagolis, the resonator in the Power Getter's B-pipe does a great job at keeping the sound civil.\

I say go Fujitsubo, but that's just my opinion.

 

I got the Wagolis a while back, very happy with it! I added the Spoon B-Pipe a month ago, sound is a touch louder, but nothing to complain about...IMO it sounds more rounded and nicer with the B-Pipe.

 

Spoon axle back FTW!
