has anyone tried the kbd targa mufflers on page 76 of ecklers magazine or the monzas on page 123 of mid-america? both of these are said to be free-flow mufflers..will these be extremely noisy compared to a stock muffler..will it increase HP enough to make it worth the swap? both pairs go for $129..i have a test pipe to replace my cat converter which i will do over the weekend..the next step would be to either get one of these free-flows or does anyone have a better sugestion? i would like to increase the HP in my 350 the least expensive way possible..thanx all :cheers:

I too would be interested in responses to this thread as I am looking at mufflers for a true duall setup

I have the monza corvette muflers....Love em...will try to take pics but here is a pic of them from a catalog.

I have the KBD Targa mufflers on my 79. I love the KBD's they are very loud in my app. due to true dual and headers. As for the monza's? I don't know I have not heard or seen them installed on a vette yet.

I have some targa's on my '84. They sounded good with the cat still on. After "the cat fell off" it was really loud! The thing sounds like a pro-stocker! I have a set of flowmaster 50's going on now. I went with 2.25" duals without a crossover. Not a whole lot of room under there for a crossover pipe. I noticed a big difference in performance with "losing" the cat.

Can you give an idea of how much louder they are than stock GM?

I had a set of the KBD's (still have them actually) on my 81 for about 6 months before I installed the headers/sidepipes. I was still running the stock exhaust system including the cat, they gave the car a nice deep tone but were not excessively loud. The response felt much better but as far as a big HP gain I couldn't say that for sure. For $129 you can't beat them, and if you had true duals they would really sound nice.

I put the KBD Targas on my 81 with the stock exhaust manifolds and cat and didn't notice to much of a change, I also had to use a hacksaw on my rear y-pipe to get them to line up straight.

I have the Monza glasspacks, with stock manifolds and a full flow cat. I don't know about HP increase but they sure sound good. After a few years of daily driving and the fiberglass burns out a little, they sound great; plus the four pipes sticking out the back look really cool. :cool :cool:

They look like good mufflers, however I run the Super Turbos I think there made by dynomax (unsure of spelling). Here's what I know about them;

1) lifetime warranty
2) have kind of 50-60 muscle car sound to them
3) not that expensive
4) don't rob any horse power; the shop that installed them ran a test on them with a couple of drag cars, they ran with out mufflers just a straight pipe and then ran with the super turbos and the time were the same.

Plus they weren't running low hp cars ethier I think the one was is rated at just under 600 hp. :eek:

I have the Monza's as shown in Mid America on my 82. Great sound, throaty but a little loud for my taste. Definately gets people's attention. Have to crank the stereo though. :cool:

Here's some pictures of the KBD Targas from Ecklers, they are usually a bit more shinny, but I forgot to clean the car before I took the pictures.

Mine are almost the same thing. Just exhaust tips, no mufflers.

In town the noise level is higher than normal, and maybe higher than many would like. It is not too high for me, and other people who are into performance cars like the sound.

Now, if I were to want to drive the car on the interstate with the tops on and the windows up for more than about 30 miles, I would want to change them. The reverberation in the back of '78+ Corvettes is as good as a concert hall. Great if it's music -- nasty if it is loud exhuast.

I've got a pair on the end of 2 1/2" duals with no cat. They are the ones from Mid America & look like the ones above, except that they don't kick up.
I'd say DO IT!!! They sound great. Normal around town cruising & idle is OK as far as noise goes (sounds good), but they really bellow at WOT :D
I did a 300 mile round trip cruising at about 3000 - 3500 rpm & didn't think that they were excessively loud (but I've been riding an unsilenced 750 Bonnie with an open face helmet & listening to loud music for 20 years, so maybe my hearing ain't so good ;) ). The real test for loudness is what the local Police think about them: they don't seem bothered by them - some even smile as I burble past!
:cheers:

I have the whole muffler/can Monza type on mine. Got them from Mid-America. I think I paid 199.00 for the set. Yes, they sound real throaty. When going by parked cars they sometime set off their alarms :D Must be the pitch or tone. They are definatly not loud. I also took a pic for ya. Good Luck, L8TER, Paul.
