2.8 straight pipe question

[Bonerpimpson]

Looking to straight pipe my 98 2.8 b5. I'm keeping my cat just deleting the muffler & resonator. I'm attaching a link of the exact sound I want. Any feedback on which diameter of piping I should run?

Don't delete the resonator. You'll get stupid drone and rasp will be terrible. Just delete the rear muffler.

Here's my video, of just the rear muffler deleted, resonator and cats still in place and muffler replaced with 2.25" straight pipe

Sounds good bro. I honestly want to go LOUD without deleting my cat.

You can go from OEM 2.25" to 2.5" straight pipe from the resonator back. I highly recommend keeping the resonator.

Anything more than 2.5" on a 2.8 is overkill. You'll mutilate your torque curve and probably won't see any till much later in the rev range.

I'm really not a speed type of guy

Go for it then

Okay so I deleted my muffler. It sounds very good. Now just going to weld 2.5" piping. Thanks for the help
