FAQ: Mufflers?

well lol, I waited a couple of days and they're on backorder at jegs, and could take a week or two, so I ordered em from summit, must be popular

Has any one had any experience with the Cherrybomb Turbo II's? If so good / bad? They are 29.99 at AutoZone and I was thinking about getting a pair and having an exhaust shop fab up a 2.25 in cat back system for me.

avoid. Although some people like the sound on V8s because they are loud, I don't think they will sound all that good on a SC V6. It is basically a straight through resonator. They are of poor quality (expect it to rust fairly rapidly if you live in the northeast) and will be very loud.

Performance-wise, I don't think they are that awesome refer back to page 2 for the flow ratings. 239 cfm. I never found the source for that article, and I always thought they were a bit low, but 239 is not good for a modded riviera.

2x239= 478 (because you have 2 mufflers)
478/2.2=217.27

217 is the amount of hp that system can support if you use those particular flow ratings. PLEASE take this FWIW because all the numbers seem low based on all the other tests I've seen.

Looking for someone who has either of these on their Riv and feedback on sound and drone.

My plan is to run ZZP 3" DP to Magnaflow (Carsound) 3" in/out cat, then either go 3" or 2.50" back to the split with either a single or dual above mentioned mufflers in 2.50" or 2.25". Might do the single muffler to eliminate the split and keep cost down.

Post your opinions and your set up, ie; stock DP / Cat / Res etc.

Thanks

I would go with the max flows. They flow more than the aerochambers though both have excellent flow. They will be a bit louder because of the straight through design. The maxflows are almost an exact aluminized steel copy of the stainless steel dynomax ultra flos.

You may want to spring for a resonator, as it will really help control drone more. If you go for a single exhaust, I'd say go 3" dp, 3" resonator and a single 2.5" maxflow. If you want to go dual, 2 x 2.25 will support more hp than you will ever put out.

Oh- I forgot to mention the resonator. ZZP has a 3" Flow Pro which is chambered, or a 3" "whisper" resonator which is a straight thru with serated tubing to remove ALL drone according to ZZP rep.

IS FLOWMASTER THE BEST... I WANT MY CAR TO SOUND LOUD LIKE IF IT HAD A V8..LOL.. WHAT SHOULD I DO.. IM NO MECHANIC AND HAVE LITTLE KNOWLEDGE ABOUT CARS?? PLEASE HELP.. I DONT WANNA PUT SOMETHING AND ITS GONNA SOUND LIKE A MOTORCYCLE.... PLEASE HELP

There is no way your going to get your car to sound like a V8. Only a loud/deep V6

I have flowmaster 40 series on my car with no resonator. I think it sounds great. Others like the turbos.

There was someone on here (won't mention any names) who had straight pipes before his mother made him take it off and that sounded pretty good too

LOL.. YEAH I THINK I KNOW WHO U TALKING ABOUT.. WHATS BETTER? STRAIHGT PIPES OR FLOWMSTERS??

Its all personal preferance. I like the flowmaster sound but I also have never heard the straight pipes up close only online. I'll get you a sound clip of my flowmasters in a little while.

AIIGHT COOL THANKS MANN.. I APPRECIATE IT

A cam makes these engines sounds pretty good, imo. Otherwise, I prefer to keep it quiet. V6 = noise.

Straight pipes would be almost as loud and annoying as TYPING IN ALL CAPS!

lmao aaron..

i'm getting attached to the sound of my straight pipes, but still looking forward to getting that max flow on.. i'll be able to hear my fwi better when it quiets down a bit

flowmaster is the worst. Stay away.
read my post about exhausts somewhere in the series 2 subsection

Where is info to support Flowmaster is bad product? In what way do they fall short?

this forum is the first place i've ever heard of flowmaster being bad. everyone i know who uses it loves it. perhaps they just don't have any products that are great on rivs?

no they just have good marketing. They consistently turn out close to last in flow tests and hp tests, but people like the sound. Check out the the flow specs. They get their "unique" sound with their chambered design, which basically bottles up the exhaust and slams exhaust pulses into each other. Sure, it will outflow old OEM stuff but if you can get a muffler that flows 3 times as much for the same price, why go with the flowmaster? I think most modern (good quality) aftermarket mufflers will yield similar results on a DD and the choice is really about what the owner thinks of the sound. But flowmaster, to me, is one of the few bad choices out there. VERY low bang for the buck

this article makes for interesting reading. FWIW

GTPs have a similar exhaust set up, with a resonator and dual muffs.

I have no personal experience with flowmasters on the l67, but people seem to complain about the teeth chattering drone. Other folks love it I suppose. Flowmasters prolly sound awesome on turbos and V8s.


I am very happy with my Borlas, and I plan to keep them until my mom makes me change them.


What about those: Dynomax Hemi Super Turbo? Maybe these are just as good as the Borlas for half the cost?...

I received my slp headers and HP tuner today. Should be installed by tomorrow. custom intake has been made (4" polished aluminum with custom box keeping out engine bay heat). Will have the rest of the exhaust installed first of next week... 3" ss pipe back to the Y then 2.5" out the end. Need to find which mufflers would sound the best for the sc 3800. Are there mufflers specifically for turbo or supercharged apllications? I wan't some noise but yet need it civil.
