I bought the full stock gst catback from RRE the other day for $30 and I put the midpipe (from cat to muff) next to the stock RS exhaust and it doesn't have the same bends AT ALL. I thought that the full catback fit on our cars too. So I guess my question is does the stock gst midpipe work on our cars cuz the routing/hangers would have to be different, right?


Note: Don't post if all you're going to say is search. I searched for awhile and didn't find shit except "ohhhh well i think they're suppose to bolt right up".

unless you NEED to replace your mid pipe, dont worry about it. IIRC the piping diameter is the same on RS/GS and GST alike anyways. most people just get the axle back muffler section and bolt onto our stock exhaust.

this might help
it is a write up on how to do the swap
from what it says
the gst should bolt right up using the same hangars

I took some pics of the exhaust, can anyone confirm that this is a 2gst exhaust? I also did some measurements on the pipe diameters.

GS-T pipe diameter



RS pipe diameter



The midpipe

I don't know what the hell you bought, but that does not look like the exhaust for the GST. maybe GSX?

GST catback should bolt right up stock for stock...

ya thats what im beginning to think that its a gsx exhaust...oh well i only paid $30 for it and i had someone pick it up so RRE gave me the wrong shit but i still got the gst muffler and it sounds good.

Thats a GSX exhaust.

The GST midpipe is identical in every way to a 2gnt midpipe except there is an extra 4" resonator you dont need or want.

Just put the GST/GSX muffler on and call it a day.
