Mid pipe muffler
Mid pipe muffler
Has anyone taken out or put in an aftermarket Mid pipe muffler on a GS3 before? I'm trying to figure if there is any performance gain from them or just lose more low end torque? I want to cut that mid pipe muffler and install another magna flow muffler to match. Any benefits guys or just more noise? As of right now I have OBX headers, stock Y, Mid pipe muffler than 2.25 piping back to magnaflow mufflers.

Basically, the mid pipe muffler (98-00 it's a muffler, 01-05 it's a resonator) replacement will give you slight performance increases at the top end of a 300, you'll suffer low end torque as a downside. A 400/430 should see modest gains with this mod.
Deeper tone, throatier (is that a word?), and better top end.

What downpipe are you talking about? Unless it's for a aristo GTE motor, I don't see how US spec cars will benefit from a downpipe since we have no use for them. If you're talking about the Y-pipe section where the 3rd cats are, then that's a different story.

Im talking about the Y-pipe section, I just really want a definite answer on the quality of the megan pipe and if anyone has had any leakage problems with them....for some reason, my GS is having bad exhaust leak problems, so, i've decided to swap everything including the headers. Im looking at the OBX headers and the megan downpipe for now, im just hoping to gain knowledge from the gurus here before I make a definite decision.

I like them. Car sounds a lot more aggressive now which I like esp. driving next to a wall barrier or going WOT. Car picks up quicker mid/high RPM ranges. I don't have any CEL on right now due to the fact I've installed a dual output sim. CEL comes on from time to time getting a P0171 code I still can't figure out what it's from. It seems to come on when it's over 70 degrees out but besides that it stays off. I have a OBDII reader so I just read it and clear it. I might have to post the freeze frame data on here when it does come back on and figure out where it's coming from. I'm thinking it's from the Bank 1 Sensor 1 O2 b/c some antiseize got on the sensor itself.
