I'm running a Greddy full catback w/ flowmaster 2.5 cat now.
I got a noise pollution ticket the other day ( our local cops are being huge dicks lately ) and have to take the Teg. down to get a fix-it ticket straightened out.
I was just wondering if a '99 4dr GS-R muffler or RSX muffler would fit on my '99 2dr. Ls without welding pipes or adding hangers....just a temp. fix for the weekend.
I have access to both mufflers for free and need to swap out the Greddy can for a stock muffler by Friday.....

Any suggestions or knowledge by experiance?

Thanks in advance
