I plan to dump... But the car is for track-use only.

EWG dump is great if you're under 23 years old for about 3 days then you get sick of it and wish you had routed it back into the exhaust.

I've only heard 1 glass pack on an EWG and it just had a different obnoxious sound, not better.

But hey, I'm an old effer (not Corky old, but old enough ) according to that douche at M.net.

One other bad thing about dumping the EWG is you can't hear **** else like detonation that would make you want to get off the gas quickly.

One more thing. I like quiet when cruising and driving around town under light loads. I don't need to be in boost all the time, but when I am in full boost, having the wrath come out isn't a bad thing. That is why I like my HKS SSQ BOV. Under full throttle and lift that thing screams "don't eff with me bitches". I love it.

Thanks for all the input. I am snagging that new turbo this weekend. I guess the outcome will depend on how motivated I get.
Lemme know how much your looking for at turbo, I may have to pick it up from you.

That has been my only complaint about running a 60mm external gate on my RX-7.

I'm not venting my Miata setup as I'm running an internal gate, if I were to be running a real wastegate I would just vent it as it's easier than recircing it back into the downpipe and also keeps it easier for downpipe removal/installs.

I WOULD NOT recommend venting a internal gate, those flappers never seem to seal 100%.
