In case anyone else wanted to know, Chris from RPM finally got back to me. He stated they are the GT part and said he'd look into the miss information on the website.

 

So what is the difference between these two FRPP/Borlas?
M-5230-GTA* & M-5230-5GT*

FRPP's web site states that they are both loud and throatier. Which one is the one with the small tubular mufflers (the ones that look somewhat like the SLP LM's)?

Thanks for your help.

 

The M-5230-5GT are the smaller tubular mufflers and are louder than the GTA's

 

well just ordered the M-5230-5GT, from john bleakley ford. I tried dallas mustang for the 319, but he said they are selling for 424.00. Bleakley has them shipped to the door for 367 total. Excellent deal i believe. Thanks for the great info here.
