well, if your miata is turbo, and doesn't have a 3" line... go get one...
its a totally different car,
boost comes on stronger, spools sooner
sounds amazing (kinda loud right now though, need muffler)
i will post vids tomorrow
setup is as follows
intercooled greddy, about 2 inch's of the greddy downpipe remain, right where the bend happens, then its 3 inch all the way to the bumper
i have no cat, no resonator, no muffler
its retarded loud, but i get spool in any gear, at almost any rpm
if u haven't gotten a 3 inch line, go do it, right now... go...
yea.. i was stock, its like night and day, ill post vids of it tomorrow.
its soo loud, i don't recommend anyone running no cat, no muffler.
its just too loud, and raspy
however, i had my gf drive it, and you could clearly hear the turbo spool
it sounds like your behind a big truck, the kind you can hear the turbo spooling in each gear, no matter how lightly they get on the throttle
I just ordered a Straight 2.5" mandrel bent exhaust no muffler from enthuza. I still have the stock greddy DP and a gutted cat. I'm hoping a 2.5" system once completed wont be too loud no cat no muffler. Get some vids up I need to hear how it sounds.
I saw you post over on CR.net and wondered how long until you wanted a muffler. I had an SRT-4 exhaust cut up under my car with no cat and no muffler. It wasn't bad at first, but after a few months it was too loud.
If you put a turbo style muffler on you shouldn't notice much difference in power. I had a 2.5" turbo back with a dynomax turbo style muffler, great tone and spool. The stock Greddy dp flange is stupid. Replacing that makes a huge difference (obviously).
