Grocery Getter
Well my 355 rebuild is going but not to happy with the sound of the exhaust it sounds like a Grocery Getter.
If I put diffent ratio rocker arms 1.6, 1.65 or 1.7 will this give me a nastyer sounding exhaust tone.
If it will change the exhaust tone should I do both intake and exaust of just intake or exhaust.
The car runs good but I now want a little nastyer sounding car vett not like a Grocery Getter.

Nah wont make any difference really. You need more lift to take advantage of your heads, like lots more than you have now. once youre moving more air your note will change.

Head flow at .500 / 253 intake, .177 exhaust

Here's my stock vette thru my sidepipes. A stocker would sound the same thru aftermarket cats and glass packs.

Marv,
Your cats quiet your car enough to be legal. My stock engine has the sound you are looking for. I have no mufflers. Not a lope, but a deep throaty sound.

Marv, Its sounds good to me. I can listen to my music. It has a deeper pitch. When I went to get new mufflers, my muffler guy told me this is what to do. So he did this for me.

Marv, my 84 had eliminators on it when I got it. At cruise it wasn't much different than muffled, but around town the mufflers made a nice difference. It still drones some inside at low speeds (and mines' an automatic so that makes it worse) but once you're up past 1600 or so it's nice and "performance sounding" inside without being obnoxious.
Hope that helps.

The C4 really is good at getting groceries with the deep area behind the seats that is if you own a coupe. The verts on the other hand are useless.
I have put 2 sets of golf clubs in the back as well as lugguge and other items.

Thanks Theres a member of anouther fourm thats going to help me out getting Real Hi Flow 3 way cat.
Like I said the smog guy not going to crawl under your car looking for a EO number.
I going to try this first then If I dont like that I going to try a Corsa system I sell my Magna Flow Cat back system.
It sounds like the Corsa has more rummble to it but at cruise it nice.
