Change the Exhaust or stay same? Hey guys new to this forum and new owner of a 99 TA M6. I bought the car with hooker shortys, with a y pipe and then into a flowmaster muffler(no cats). I have been planning on getting probably the TSP headers and true dual exhaust thinking it would be needed and make a difference. I plan to buy a head/cam and a fast intake with a different TB. I guess my question is, will it even be worth it to change the exhaust to LT and true duals or can I stick with what I have now? thanks for the help and all the other great info you guys give out.
Shorties and the Flowmaster cat back are 2 of the worst things a head/cam ls1 car can have for exhaust based on all the information and results threads I've seen on this site.
It is well worth the upgrade to TSP 1 7/8" longtubes and duals.

Definitely get rid of the shorties AND the flowmasters ASAP. I wouldn't even wait until you get the Heads, cam, and intake. Switching from what you have now to a set of TSP 1 3/4" or 1 7/8" headers and a good flowing catback will be a big step as is.

ok well I had been looking at getting some Pacesetter LT and then the TSP true duals. Any fitment issues I will have to worry about? I just ordered some SFC from Founders so hope I will not have issues with that. Thanks for all the help guys, new to the newer cars. The only thing I had owned as a fun car was old muscle cars that seem so simple compared to these.

Another thing I have been wondering is what I should do first, buy a new TB/Intake or H/C? which one will require changing over more stock parts? With a H/C can I still use the stock TB and intake? obviously I wouldnt be getting the most out of it, but if I have to spend 1k for new exhaust, I wont be able to afford doing all at once like planned.

I am not saying all are bad, but the design for our catback is. The single chambers flow great however any bullet muffler with same internal diameter as the pipe will flow better.
The one in two out flowmaster muffler offered on our catbacks are known to flow like ****. Use search and you will find 1**** examples of this.
