B&B Tri Flow Exhaust

[Doutdoor]

Does anyone have any experience with this exhaust system. It looks like a well built system and I like the exhaust tips. Any feedback would be appreciated. I'm looking for a good system. I've also looked at Corsa and like what I saw. This is for a 92 LT1.

Thanks,
Dave

depends what type of sound you want..

My friend has the B&B on his 94 convertible.. nice deep throaty Sound..

Corsa sounds okay but is too quiet on a stock corvette..

I know several people in the Seattle area with B&B Tri-Flow on their C5. It sounds terrific. Don't know about the C4.

BTW, CMCS is sponsoring an outing this Saturday, 4/20. You're welcome to participate.

When my Dad was in the Northern Alberta Covette Club quite a few C4 owners used the B&B Ive heard nothing but good things about them if that helps.

Dave,

On my 86 vette I use the 2,5" after kat system, it look hot and it sound hot. If you are looking for a silentssystem, buy original mufflers. If you want something hot, buy B&B.

My friend has Corsa 3" under his zr1, this is hot also. Good kwality and performance.


Al the rest sucks, believe me.

I sure like my Dynomax SS Mufflers, also the Borla are a excellent choice.

 

[johnny]

I am so sorry, I forgot de dynomax mufflers! But I do not like the Borla's, I had a Borla's before and they add NO extra power. Not one single hp.

 

[BigRed]

Really! Wow for the money they are you'd think they would give you something..huh. I know the look good and are stainless but forget them if they ain't a good performer.

 

[johnny]

and something else, I had a Borla under my JEEP. It cracked after 100 miles.

I had a new one okay, but it still cracked.

Dave,

I've heard a Tri Flow on a 94 ZR1 and the sound was just earth shattering #@$#

It was very intimidating.

Borla mufflers WILL improve your power & torque simply because about every aftermarket muffler has less backpressure than the stock mufflers. This means that if the power increase is zero you have a restriction elsewhere, most likely in the catalytic converter.

Furthermore, the stock 2-1-2 system isn't very good, the 2.5" pipes are restrictive. You should go for at least a 2,75" system or better yet duals (at least 2,5")

The only marketed muffler with close to 0 backpressure that I know of is the Borla XR-1.

A cat back system (after cat?) is NOWHERE near effective enough for power levels over a 250-300 Hp. The front Y-pipe is one of the most restrictive parts after the headers.

There's no substitute for a good handcrafted 2x 3" stainless system!

I had a conversation about HP improvements with respects to the exhaust on a guys Mustang. He bought Flowmasters and said they advertise a 10% increase in HP. I told him that he would only see a 10% increase if he optimized the whole exhaust system from engine to tips. Am I correct?

From what I've read here in the CAC, any after market performance exhaust is better flowing than stock. I do believe that it is BigRed who stated that the C4 exhaust is more restrictive than the C5, thus you would notice more improvement.

 

[Twin_Turbo]

Yes, all stock systems are restrictive. I'm not sure what to say about afvertized improvements, usually it's in combination w/ other stuff as a marketing trick..

Also, an increase in percentages is silly, that means the more power you start w/ the more gains but actually when you'r running a lot of power the header size quickly becomes restrictive again.

Mmmmmmmmmmm..................

Indeed, the stock mufflers are resticted. But when you buy aftermarket products, buy the best.

You buy a B&B or a Corsa. I think Dynomax is also good.

Value for the money.

Borla isn't cheap either.

And, on the Dyno I did not see any improofment, with the B&B it does.

 

[Edmond]

Guys, go easy on me, it was only a Mustang LOL.

I personally went with Flowmaster and the system should be coming in next week. I can't wait to install it because I know it's a definite improvement over what I have now, which is basically stock. After I install the catback system, I'm going with a HyperTech chip and then open up that air filter.

 

[Twin_Turbo]

Did you dyno the same setup w/ the B&B and then w/ the borla's (or vice versa)??? I find this very strange, a buddy of mine dynoed quite some combinations and has found the borla's to outflow about anything. I'm not talking about the XR-1's here but about the stainless ones!

Exhaust Systems

From what I've read guys, a system called Power Effects will out flow any system. Their testing reveals a 55% better flow than stock. The Borla system was next at 42%. The Power Effects system is a complete stainless steel 2.5" tunable exhaust system meaning you can adjust the exhaust flow rate by turning valves on each muffler to attain the sound and performance characteristic you want. I thought that was pretty cool.

The tips are black though and still look pretty nice, although I think I prefer the chrome tips on other exhaust systems.

 

[Twin_Turbo]

The PE system uses little motors to open and close a valve in the exhaust.... that's a little ricey for my taste.

Are you talking about the cat back system here?

I have a Bassani Quad Catback on my C5 and I love the sound and profromance.
