Installing Varex Suitecase Muffler on JGC Summit 5.7 HEMI 2015

I searched allot through the internet and couldn't find anyone fitted the Varex suitcase mufflers from Xforce on a 5.7 JGC Wk2.

Is it ok to replace the OEM muffler with the one of Xforce and does it require any reduceres while installing?

Can cause and damage/problem to the engine?

Re: Installing Varex Suitecase Muffler on JGC Summit 5.7 HEMI 2015

If you are asking if reducers are needed then you are using the stock pipe. If that is the case, the muffler will not simply slip in since the inlet pipe spacing is not the same as the outlet pipe spacing.

A piping diagram of the hemi, https://www.google.com/search?q=2014...8i4_F3Bgn6M%3A shows the flow looks the same so that is ok.

No way will it bolt in. You'll need to get four 2.5" muffler flanges, four 2.5" gaskets and eight, grade 8, black oxide nuts & bolts for the stock pipe to mate with the exhaust. Plus some extra pipe to deal with the different spacing between the inlet and outlet pipes. All info I've been able to gleen is the stock pipe size is 2.25". A pipe expander will easily enlarge for your to weld on the flanges. Or, weld a 2" long piece of 2.5" pipe o'er the 2.25".

IMO, this is an expensive exercise with no performance payoff with the exception of uniqueness of controlling exhaust sound. That's prolly the reason no one has done it yet. An alternative would be to ditch the OEM suitcase and replace it with a Dynomax X-pipe 54777 for $114. Hope this helps.

I was looking at the suitecase muffler.
when I contacted them they told me it is possible to fit it on my WK2 if I choose the right size.

Wow ..

That’s really an extensive exercise which am definitely not going to carryon.

I was thinking about the X-pipe but the problem is I only like to have thesound for a portion of the time to the Full time.


Any was that was a great help "midsouthduckhunter"

Thanks allot
