Welcome to CHR!

We're a pretty knowledgeable bunch of guys and gals that run the gambit from nearly stock to extreme competitive, professional builders. The exhaust question will certainly bring a few responses. The internal combustion engine is really just a big air pump and any time we can improve the flow it's typically a good thing. That said, your current exhaust is probably fine for a near-stock build. Tell us a bit more about the vehicle, the engine build and what your plans are for the car.

In my humble opinion, 2-1/2" pipe from each side (preferable via headers) to an "X" or "H" crossover and 2-1/2" through 40 series Flowmasters all the way to the rear bumper with chrome tips is a perfect setup for most applications. Looks cool and sounds great but before contemplating such, you need to make sure it will comply with the regulations in your particular area. Here in Oregon, 1974 is the magic year and anything made after that needs to pass our Department of Environmental Quality (DEQ) inspection and they can come down real hard on any exhaust modifications that do not include the original catalytic converter(s) and all related plumbing.

So tell us what you're working on and we'll chime in with probably more advise that you ever thought possible!

Regards,
Glenn
