When I picked up my '60 biscayne, it was put together muscle car stlye. 327 headers and Flowmasters. I threw on some glasspacks in a hurry and now it sounds like a fucking tractor hahaha.In the back of my head I knew it would end up that way cause of the headers and the big ol exahust pipes. Buddy of mine told me about these Hushpowers. They are meant to go with the headers. I'm looking for a nice good cruising rap. Has anyone heard them??
My father in law put a set on his 32. It has a 302 ford relatively stock motor. They sound good. We built a complete stainless exhaust with tail pipes over the axle and out the back. They seem to be very well made mufflers and we did just as FM said you can do and mounted them real close to the floor pan. They did exactly what they are supposed to do, they stayed cool as far as compared to other mufflers. The only problem is that they are so damned expensive. I wanted to put a set on my sedan but I used smithy's instead. I wanted it a little louder and I built my entire exhaust for less than the hushpowers would have cost. I would like to hear them on a decently cammed chevy motor. Most small block fords just seem to sound a little flat to me.
Had them on my truck with a worn-out 350. They sounded perfect. Then I put a near-400hp 383 in (with same headers), and they became a whole different muffler. Still sounded good, but a little louder than I wanted, so I put Super 40s on instead. If it's still up, I videotaped the sound variations between the Hushpowers and the 40s. www.classictrucks.com (hopefull it's still up)
We put them on 2 BBCs, too raspy like a redneck caddy(pickup to you city folk) with glasspacks. I have yet to hear them on a smaller mill.
Nicely done video. I've been curious as to what the hushpowers sounded like for quite some time. Thanks.
Did you click the link? Go to Technical Articles and scroll down to the Flowmaster story. The video link should be in there.
we have run the hushpower flowmasters on several cars here at the shop. the customer mainly wants them because it it quiter inside the car than the 40 series. Make sure you run an H pipe before the muffler or you won't have equeal flow and it sounds like crap real popy at higher rpm. also just a note the flowmaster hushpowers and 40 series are only rated at 400 horse power. I just blew a set out on my truck with a 454 in it. and flowmaster won't warrenty it.
Super 40s are rated for over 400hp, which is why I switched to them from the Hushpuppys (which are rated at approx 200hp max each). And according to them (FM), the H pipe isn't necessary in lower hp applications.
I put an H pipe in my sedan when I built the exhaust. Every one claims that it produces a much better sound than with out. I am not worried so much about free flow. I figured why not since I was building it any way. What do you think, does an H pipe or crossover change the sound that much? Didn't mean to hijack!
they are only a $120 and that is only $20 more then a regular 40 series. the H pipe does make a difference. we have a 37 without and a 35 with and they sound totaly different and they are running the samegm create motor. the 37 without an H pipe gets real popy when you reve it up from idal.
No. And while I might be interpretting my info differently, crossovers and H pipes are for "audible" differences. I had a guy write in and complain about the differences in the bending processes...that non-Mandrel bent pipes cause a drastic reduction in performance. BS. When the numbers were actually crunched (for a street engine), the differences were insubstantial. The cost to have a complete Mandrel-bent exhaust versus one you'd get at Joe Blow's Muffler (that's a good name...I might TM it!) isn't worth the minute difference in performance aspects.
