downpipe question - Page 2

On my sti (turbo back taken off my old wrx) i'm currently running an Invidia downpipe with a Megan racing catback going to be protuned w/ the Accessport. +1 for Invidia and Megan racing. It's a really tame note even at wot!

Yeah Cobb is great, but expensive! I Like my Invidia downpipe though. You can get an Invidia v2 downpipe from RallySportDirect.com - WRX Downpipe - Performance Upgrade Parts for $244.79.

Not too sure that the DP bung is far enough from the turbo to be safe (burn the piece). I could be wrong about it being too close.

Its almost in the perfect spot. At least thats what Tim Bailey had mentioned to me when I asked about it during tuning my car. Its also the one he used to plug in his wideband to tune my car.

any of u ever hear of megan racing

newtothegame · 11-06-2009, 11:33 AM

I havent heard of megan racing brought in awhile. But when it was talked about before, people where happy with them. I have never personally heard a WRX with a Megan exhaust.

how much do u think it would cost to have the local muffler shop to make a hole for the o2 sensor

man show · 11-06-2009, 08:29 PM

It's a pretty easy job... drill a hole, weld in a threaded piece and plug it with a threaded plug. I don't know the going rate for a few minutes of labor, but you could probably have that done for 20 bucks (+/-) if you shop around.

ya it shouldent be that hard to do do u
think u have 0to buy a threaded piece that matches up with the o2 sensor

pzr2874 · 11-09-2009, 05:54 AM

^^ Are you referring to the bung at the top where the o2 sensor would NOT go ? Or are you referring to the area where you would want to put the wideband in ?

WRbluewrx · 11-09-2009, 02:55 PM

were u would want to put the windband o2 sensor

Buy the wideband you want 1st, then look into installing it / tapping and welding the bung in (safer way IMHO). Pretty sure they are all the same size... BUT ..... you know how that goes.
