For the guys who are not CorvetteForum members here you go:

FLOWMASTER VS B&B


Well I finally took my car yesterday to an exhaust fabricater located in my home town. It turned out this guy really knew his stuff, and wouldnt be happy until the job was done right. History-I bought the car roughly 5 years ago. At that time it had the stock exhaust system. I knew right away that had to go. I decided to purchase a set of Hooker 2149's with the matching front Y-pipe. I then decided to purchase the random tech cat to fit the car, and the Flowmaster Force II catback system. I cannot say anything bad about that system. For the price it was a damn good system, and it sounded awesome!

Fast forward to yesterday. I bought a B&B system a few months ago. The system was used with around 4000 miles on it, even though you wouldnt know it. It was on a 1996 LT4 vert. I then contacted TJWONG to buy some bullet cats from him. He mentioned he had some cats that would flow in the neighbourhood of 575cfm each, so I decided to get those as well.

My car is pretty much stock. For the way it sits now. The system that was on the car was PERFECT! The B&B system I put on was overkill, and I know that. However, I am thinking to the future as I will be modding my car probably for the next few years. Thus, I wanted a system that would flow more cfm, and I got it.

FLOWMASTER


The Flowmaster system as seen above was great for the money, and it sounded great. I might even miss that sound. However the system was aluminized which is good and bad. The good is that it's much lighter then the B&B. The bad is it will eventually rust after many years. The Flowmaster had a barking sound all through the rev range. It was the type of sound that made people's head's turn. It also is not as nice looking as the B&B.
B&B











The B&B has ALOT more drone then the Flowmaster at RPM's around 1300-1900. It has an louder idle I find, but when nailing through the gears its quiet. This is the biggest difference between the two. The more revs the B&B gets quieter, and with the higher rpm's is where the Flowmaster got LOUDER! Now keep in mind, the B&B was installed with the reasonator and 2 bullet cats. It's a 3 inch system, and alot of the back pressure of the Flowmaster system is lost now. My car sounds alot more similar to a LT1 or an LT4 now going through the gears, then it ever did.

PERFORMANCE

I believe the car is a tad slower now with the B&B system. The car used to trap 100-101 with the old Flowmaster system, and this is a stock L-98. The B&B system is ALOT heavier which of course will slow the car down. You might think I am looking into it too much but, I feel as if I lost a little torque down low, but in saying that the car seems to breath a little more up top. Its seems alot more happy in the 4800 range then it certainly did with the Flowmaster. Which is what I will need when the car spins in the 6300 range.

But I have to say. If you dont have a good exhaust guy, Dont bother doing this system. It is far from a bolt on procedure if you have Headers, and the L98 motor. This guy is a good welder, and a great fabricater so I lucked out. If there are any guys in my neck of the woods that need exhaust work. I would recommend this guy. I wanted true duals, and now I finally have it!


Have a good one!

I can't help but ask what you think of your tires? The reviews on tirerack say they have a lot of road noise, but they are relatively inexpensive. My Vette will need tires soon but I dont want to spend a lot.

Roadnoise? Hmm. News to me. You know what. I wanted a nice tire, with a wicked looking tread pattern that wasnt going to break the bank, and if I was to get stuck in the rain they would hold there own. I think for $115 a tire or whatever they are worth now, you will not be disappointed.

They are ALOT better then my old tires which were the 712's. The Yok's are a much better tire then the 712's.

But if you can afford it, go with the MX's. However in saying that, They wont last as long as the ES100's.
