3In exhaust with Magnaflow 22' muffler, Sound quality/DB level?
Hey guys,
Got my exhaust made for my car. Used 3" ss pipe from the Downpipe back, downpipe is a beautiful artech SGDP. I've got 3 vbands on it, 2 at the cat 1 at the rear. No resonator, using the 5x11x22 in magnaflow muffler used.
I've got a bit of a noise issue with it. Its not to terribly loud at cruise, but I took it to redline the other day and I'm surprised I'm not perma-deaf.
I'm thinking I've got a leak at one of the multiple vband clamp bastard things. but maybe 3ins is just too loud for me. So i'm checking with other people to see if their similar setup is fairly loud, or no.
My turbo/manifold/downpipe is all pretty secure. its an FMII w/gt3071. I've got gaskets and sealant at all the connections, rene-41 hardware and such. Doesn't stretch, and its all verified tight. also, the majority of the sound is from the rear of the car anyway.
Thanks,
Nick

I don't think the larger turbo would make more noise really. its not too much bigger than a 2871. I dunno. Honestly it doesn't look like it impedes flow much less than a smaller one. Still a big fan blade in the way, still an imediate ninety... should muffle sound good.
Pretty sure I have exhaust leaking from every orfice of my exhaust system. God damnit.
Sure is nice its -13* out so I cna go outside and work on my car on the ground in a tshirt.

Having dealt with exhaust leaks from every possible orifice, I say this
If it is smoov and bassy, that is just the sound of the exhaust
If you hear nasally higher pitched raspy ****, you have a leak
If when boosting you hear the sound of air wooshing other than normal compressor intake sounds (my 3071 woosh is LOUDD and i like!) then you have a leak

Damn. Ok, Ok. I fucked up. I'm betting I know what happened.
1. Suck at welding
2. spatter on vbands = no seal
3. ****.
I guess I'll either try using a gasket on those affected vbands, or weld it straight at those points. Should be fun for removal.
there's that, or just have Abe do it for me. I work too much for this crap. blah.
Really, the 22in muffler is that chill? I miss my stock MSM crap, it wasn't half bad with no resonator/fm downpipe. Long behind me at this point....
