Please help, 4" exhaust MBRP & Magnaflow

[TampaDieselFX4]

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.

I got a Silverline 4" turbo back with 5" tip and no cat. It fit perfect, no clearance issues with downpipe either. It's been on for about 1 year, I checked all the bolts, clamps, etc..and still were all tight and no leaks. Paid about $400.00 bucks for it and have no complaints. Hope this helps.

I picked up the magnaflow for mine. It has a 4" down pipe but it was an easy install and no clearance issues. Got it off of Magnaflow Exhaust Solutions-Hottexhaust.com. Think it was around 380 bux for it. My truck was short enough and there was enouth pipe left to make it straight piped too.
