Best Sounding Exhaust for the ZR-1

[32valvesftw]

After a while with my set up, which is long tube headers, no cats, x-pipe and Borlas mufflers I am thinking I want something a little quieter. Does anyone have experience with Flowmasters on the LT-5?

My first 91 was done by my friend Jeff. He used the small tube Watson headers and the old 3 inch B&B and I thought it was the best sounding. With the 4.10 gears it had that resonance everyone complains about but I loved it cause I'm deaf and just love loud. It was a strong running car with no major engine mods.

So now the new 91 I have has the long tube headers , no cats, and the 2.5 Corsa that Mark installed when he did his engine package. It sounds really great to me. I was considering changing it out to a B&B but I like the older ones. I think the best thing is to not screw with what Mark did especially after seeing the dyno sheet.

I have the Flowmaster exhaust that was designed for the ZR-1. I found the system on eBay, it was brand new without mufflers. I put Flowmaster Delta Flow Series 50 mufflers on. I think it sounds great, to top it off I put Flowmaster chromed angle exhaust tips on. If you can’t find the Flowmaster exhaust you could still go with the Delta Flow Series 50 mufflers.

It appears BB and Corsa are the two most used exhaust systems on ZR-1's. Wondering if Corsa has less drone than the BB? Thanks

B&B (old style) is very loud with lots of drone.
Corsa cancels much of the drone, and as a high pitched shriek at top end.
It’s really very subjective, a matter of personal taste. I have Watson’s, no cats, X pipe, and 3” B&B’s deep and nasty.

I think my modified LT1 stock exhaust system is great . I removed my power effects system so i could install exhaust cut outs. Brought a used LT1 exhaust system,removed resonator made my own " H " pipe and added 3 in cut outs
just before the mufflers. I did not want the spare carrier so cut outs are in a good location. Switch on center consul opens or closes the cut outs a little or a hole lot . I'am running Jeal Headers. I'll be at Tony D's this Oct the 20th.
here is a pic. of my system.

You did a great job on your exhaust, looks nice.
I think I will go with the Corsa less drone than BB Thanks

I replaced the mufflers with 16" of chambered pipe; now have the C2 side pipe kind of sound except louder.

I used ss tips and plain ss 3" pipe from the mid-pipe, and like you, I find it sounds loud and right!
Enjoy it!
