Mbrp 5in owners check here

2004 extended cab

I just got off the phone with mbrp about there 5in turbo back system s6224al.
They told me the down pipe was 3.5inches.

My question is for those of you that have this, isn't the stick down pipe 3.5 inches? If so, can you bolt the new exhaust right after the downpipe without removing the old one?

From what mbrp told me is the downpipe from them is like the factory, I keep keep the new one as a spare and just use the factory.

Just doesn't make sense, why would they include a downpipe if you don't need it


Many thanks

Thats odd. I have the MBRP 4" turbo back with a 4" downpipe. Why would your 5" come with a 3.5" downpipe?

I have the 5" with 4" downpipe.

Its loud but not bad unless you dig deep into the expensive pedal.

I got the bigger downpipe with my lit.

On mbrp site it's doesn't mention dp size, that's why I called, when he said 3.5" I asked him why? He said I could get a 4" but the 3.5" is what comes in the kit, no explanation either why they would send a factory size dp on a 5in exhaust.

I'm going to go ahead and order and hope it comes with the4", hopefully the rep just didn't know what he was talking about. It's a pretty god deal at 395 shipped, so I can't lose in my mind.

I'm wanna those that are going for the looks and sound, lots dmax and Cummings up here so need to represent.

Tanks for the rplies

A stock truck has a 3" down pipe with 3.5" exhaust. The 4" mbrp turbo back kit comes with a 3.5" down pipe. You can get a 4" down pipe but it can be troublesome installing it and IMO it isn't going to give you a noticeable difference. There have been people that have 4" down pipes that have had trouble with them rubbing. Hope this helps.

Thanks for straightening me out spudman, I had it backwards I guess, I thought it was a 3" exhaust and 3.5" downpipe.

Exactly.

Stock down pipe is 3" with 3.5" exhaust. All MBRP kits come with at least a 3.5" downpipe. I'd stick with the 3.5" down pipe vs the 4", simply because of the fitment issues mentioned.

I have the 5" with 4" DP with 8" tip. It wasn't easy getting the DP in there but it is and I love it.

I'd really like to hear the difference between a 3.5" down piped 5" exhaust and a 4" down piped 5" exhaust. I wonder how much different it sounds... is there anyway you can make our dyno competition this weekend?!
