Seeking a little more sound on my 2001S

[ike84]

An easy "one off" of this type of mod is to get a long drill bit and drill into the internal baffle chambers from the exhaust tips. It has the same effect only no welding required.

I have done a bunch of exhaust mods to mine so here's my take on them (from easiest to hard)

- desnorkle. Just do it. Fantastic intake roar over 4k. Easy to do, no tools required other than philips head screwdriver, and if you're worried about the "cigarette butt in the I take" thing just duct tape some window screen over the inside of the grill.
- drill into internal baffles. Easy to do, the bit will cost you $10. There's is a drone from 2800-3000 but it will subside over time. Some really like this mod. Others (including myself) aren't crazy over it. There's a bit more low range rumble but it verges on the sound of an exhaust leak.
-china muffler. Not bad, a bit better than the baffle drilling, but drone is worse. Db killer inserts into the tailpipes help a bunch with that but then what are you really doing?
- test pipes (secondary cat delete pipes). A fair bit louder than baffle drilling, but if used with stock exhaust will not wind up getting you pulled over. I never tried it with china muffler, but I would imagine it would be quite loud. Note though that the secondary cats actually do most of the emission scrubbing and by deleting them you will fail a sniff test (although you would pass an obd2 test since your readiness checks are all still ok)
-straight pipe! Currently in the process of this using catless long tube headers and pieced together aftermarket 2.5” downpipes. I'm probably going to need hearing aids in a few months.

Hope this helps.

Thanks much for the help!

Delayed too long to order test pipes will have to wait on availability and bolt up to the stock exhaust.

I have a WTB here on forum and EB search running maybe a slightly used will become available.

Can’t wait for a little more roar from my 3.2!

Nope. Nuh-uh. Not even close.

You’re referring to the “Crios mod” and it sounds nowhere near as good as the internal exhaust mod. Not only are they not even in the same class, their classes aren't even adjacent.

Particleweave is correct, I have had the Crios and the bypass (eternal pipes are more common in the UK), the Crios is a decent cheap mod but the bypass pipes (or internal mod) are much better

Thank you, not sure but will check a good muffler shop and see if they can modify my stock exhaust (now have a 2003 and that rear bumper might be problematic). The Brombacher Sound Version are reportedly a nice sound but pricey...

Will see what I can come up maybe just remove secondary CATS no Crios mod for now.
