well 4 years has taken it's toll on the old pipes. going to get another Flowmaster custom cat-back installed tomorrow. i had the standard 50 series (3 chamber) on there, but i am going with the new Delta-Flow 40 series (2 chamber) that has additional noise cancellation fins, to reduce resonance and lower the internal sound level, from the Flowmaster site, it DF-40 should be a tad quieter than the standard 50 series.

i'll let you guy's know the results tomorrow, and if i can find my SPL meter, measure the before and after.

and provide some wav files?

By Danno on Thursday, August 23, 2001 - 05:26 pm: Edit

of course...i'll send them to ho again.

BTW, i did find my SPL meter, so i can compare the standard 50 series and the Delta-Flow 40 series.

I am anxious to hear your findings. I have to put a cat back system on and have heard that the Borla is loud. How much did your set up cost? I am in Saint Louis. I assume that you had a muffler shop to the job?

what is this delta-flow BS anyway? i just ordered a 50 series for 79.95, and there was a "delta-flow" one for 109.95. whats the difference? the lady at summit said that the deltaflow is quieter. i thought to myself, if i wanted quiet, why would I be putting on a a Flowmaster in the first place?? the mind ponders...

Brett the Bolra is not loud.

Why are you guys using FM? Dynomax muffs are 1/2 the price and are no were near as obnoxious and flow better.

By Danno on Friday, August 24, 2001 - 04:29 am: Edit

here's the results...

50 series (3 chamber)
Inside Sound Level 86db
Outside Sound Level 98db

40 Series (2 chamber) Delta-Flow
Inside Sound Level 78db
Outside Sound Level 92db

the tone is still the same, so it's not worth posting a wav-file

$79.95 for a 50? you got screwed. they should be about $68. the 40 Delta flow is $72.95 from summit, and the 50 Delta-flow is $89.95 from Summit.

Cost:
$78 for the Flowmaster (when down to Summit in Akron, OH)
$16 for a new exhaust olive from the dealer
$75 for the install, which included new pipes.
