Default Center bypass a “must have” mod for the GT3?

What do you think? Specifically for the GT3/GT3T.

For those that have gone with a center bypass... happy you did? Any regrets? Any recommendations?

I’ve seen some posts on here describe it as a no brainer, but wanted to see what the broader community thinks.

Thank you!

Aftermarket exhaust of any sorts is a must have on the GT3 imo. If you don't want something too loud then get a JCR lightweight center bypass. Best on the market imo. If you want something really loud then get the race pipes.

I'm very pleased with my JCR silenced CMB. Just about OEM noise levels with valves closed and great sound with them open.

Many to choose from. Sharkwerks, GRP, BBI, AWE, Gmg and others. Many of us also disconnect the exhaust valves when installing the center bypass.

Loved the stock exhaust sound until I rode in a friend’s with a BBI/GRP bypass. Ordered one the next day and didn’t think twice about the $2k price for a few pieces of steel pipe. It sounded that good.

+1 for GMG here! Simply perfect if deep race inspired rumble at low rpm and howling loud at WOT is your thing!
