Midpipe

[Stang27]

I have a 2017 GT350 with gen 5 Whipple that's amazing by the way. It has a resonator delete, stock mufflers, and just added a B line midpipe. It's crazy loud inside and out! I know in time I'll blow the cats off so I went with a midpipe and it's just too loud.. I have the exhaust flaps closed as well and still way loud. Any recommendations? High flow cats are stupid money so will a axel back help? If so what do you recommend?

Nothing is quieter than the stock mufflers especially with the flaps. Add back a resonator in the middle where the x pipe is. Magnaflow makes one with an integrated x pipe and it helps especially with the rasp.

Or put back 2 separate resonators (but bigger) where they stock ones used to be.

It’s gonna be loud unless you use a muffler that has packing such as a Dynomax.

GT350 and Whipple but $1,000 cars are stupid money?

How much boost are you running? and is that safe in the short term and most likely going to be an issue in the long term ?
