JJO,
We’re glad you like your Flowmaster mufflers. Do you have a video of the Delta 50’s installed? We’d like to hear what they sound like and we're running a video contest.

Give us a call about the X-pipe, we can usually work out something in terms of parts-only purchases.

yo JJO, thinking the same move as you with the 50's. Four questions, sorry. still like the setup? did it seem more unrestrictive? and the sound? and was the mid body mufflers cut out along with the resonators in the rear corners? appreciate any info, eric

All I got are pixs at the local mufflershop in Toronto (Hot Rod Scotts).

I replaced both center mufflers w/ Flowmaster 50's then eliminated
the rear resos with 3in. SS pipes from the mufflers back.
No drone at highway speeds & definitely less restriction Plus the classic Flowmaster sound.
IMO, 40's would be louder & some people prefer that. :thumbsup:
