FYI - mine are center inlet, offset outlet. (Actually, I think the UF website lists them as center outlet, offset inlet, but the mufflers are reversible.) Anyways, my muffler guy wanted em this way to make it easier. Ask yours for his opinion on how it should be configured. I personally like the spacing that the offset outlet gives.

Also, if you have a 74-82, I really recommend the stainless tips. They look great.

Thanks for the advice Steve. The offset must have something to do with where they fit and how the exhaust pipes line up I would guess. I'll check into it, I like the looks of yours fine.

Thanks..............Bill

 

I like stainless steel Magnaflow's. I strongly disagree with joe73vette. My stock 80 sounds great IMHO . No resonance at low rpm, nice purr on the highway, loud enough to hear it ,but not too loud to talk to your passenger. At wide open throttle they really get LOUD. I put stainless steel Magnaflow oval tips on mine , just for something differant.

 

I just had a pair of Flowmaster 42543s installed and I think they sound great. Muffler shop is a long-time, family-owned business. He clamped a pair of Magnaflows on the car, let me take it out on the road, then put the Flowmasters on. As I said, Flowmasters sound nice, not too loud, just enough so that, when I pull in the drive, my wife knows it's me.

 

In addition to sound, any opinions on what flows the best for performance?

 

My super turbos have performed well on my '80 with 2.5" duals, h-pipe just aft of the Bow-Tie x-member and Hedman Jet-Hot coated headers.

 

I used the Hooker Aerochambers on mine before I went to the sidepipes. They had a nice deep sound to them and weren't too loud. For the noise and flow, they make the "Maxflow" muffler (straight through design) which is also a nice muffler. Both use an aluminum case.

 

on my 78 i went to a freind at a muffler shop and had him make a bypass tube with stock 4 hole flanges. I use that until smog time in calif..... It really makes a difference on the sound and performance. It cost me 30 bucks.....it does make it louder just more tone.

 

I'm thinking that, if/when I need to replace the exhaust on our C3, I'm going to want something that's not too loud.

I've got poor luck with "loud" exhausts.

In my Saturn, which has a 2 1/2" exhaust catback exhaust, I've gotten stopped 3 times and told that the exhaust was illegal.

However, thanks to Gov. Schwarzenegger, a law was passed that if I got a ticket for it I could actually have an exhaust noise test done to show it was under 95 db at a 15' distance (this is also the same noise limit required to race in Solo II events at Qualcomm Stadium in San Diego). Coincidentally, my car just happens to be under that limit, at 91 db.

Our 1967 Jaguar, which still has the original exhaust and mufflers, sounds louder (and probably is) than my Saturn, and I got stopped once for it. I lucked out and told the cop that we'd just bought it and we were planning to replace the exhaust that weekend since we saw rust along the way. After showing him the engine under the hood, he let us off with a "nice car" and a warning.

I think, with the Vette, that I might just be pushing my luck by changing to a louder exhaust.

Anyone have any recommendations for me that'll give good performance without a louder exhaust note?

 

I have Stainless Magnaflows. Like others have said, they are nice at idle, they purr at cruise and they get loud when you floor it
