+1 to the above. also, i'm noticing a significant torque loss between 2-3k which is something I didn't expect just from just an axleback. currently related mods are M370, Berk HFCs and now these Tanabes (XYZ in sig not installed yet).

actually thinking about going back to OEM mufflers.

 

The Berk HFC's I think is what giving you the torque loss....

 

had berk HFCs for two years now. unless there's some strange interaction between the HFCs and mufflers, the HFCs are not the issue.

Berk HFCs installed 6/09
Motordyne M370 installed 6/11
Tanabe Medalion installed 7/11

 

feels much better today, 2-3k RPM closer to what it was prior to Medalions. temp and humidity are much lower than it was two days ago.

 

I just have the tanable axle back and while it should not sound like a hopped up $5K honda I am not happy. I love the VQ sound but you don't buy a axle back to make hp, you do it for the sound. Way mellow. No rasp, no drone AT ALL, but you have to "listen" for the sound vs. stock. I had a buddy do some driveby while I stood in the driveway and while you can hear a slight diff, it does not sound like a perfomance system imo AT ALL. However, under a wot at the upper R's is about the only time you know you spent $600 on amazon! But with an intake (any open filter brand) comes alive as in 1+1 =3 on most of the car I have heard and driven in.

 

axlebacks can make power depending on the application, granted it's not much but there's still some power to be gained on the top end

 

I have the tanabe axle back + mid pipe and the sound is amazing

 

so now I'm running with HFCs, XYZ w/ resonator, stock mid pipe (Tanabe mid pipe ordered) and Medalion exhaust. 2-3K rpm seems close to my original setup (HFCs and stock exhaust) but with a little performance loss at times. 3k+ rpm is a definite improvement.

sound-wise, 2-3k rpm is loud and low. 3k+ screams.

 

Thank you all for the feedback. I am still not sure what I want to do yet. I have been looking at different catbacks but I really cant see myself paying $1300+ on an exhaust which is why I wanted to go this route but performance wise it might be worth it. I have a 67 Pontiac Firebird as well and payed $500 for a custom header back system, why can't my g be as cheap as American muscle? Lol. Any suggestions on the best value catbacks available.

 

G is probably a low volume car compared to Mustang/Camaro. higher the volume, the cheaper the parts are.
