Ok, finally decided to do the 4" exhaust. I want a 4" Turbo Back, single, stainless, straight through muffler, and be able to use my stock Cat and a test pipe; swap stock cat in/out when need be. I'd almost prefer a 3.5" Downpipe for fitment and such of the firewall.
Magnaflow- #15954 XL Tuner. Supposedly has a 3.5" DP, Not sure if you can run the stock cat, or if they make a test pipe??? help. Comes with a muffler & tip.
MBRP- # S6206409. 409ss, you can use stock cat, you can run a test pipe, has muffler, has tip, 3.5" DP.
Can someone help me with the magnaflow system ?'s please.
