Spintech...

'72customdeluxe · 05-26-2009, 08:45 PM

Borla xr-1 ftw. They sound soooo good. They may be expensive, but they last forever. Aluminized mufflers will rot from the inside out pretty quick. Painted is even worse.

72truckman · 05-26-2009, 09:49 PM

Thanks for all the recommendations! I im leaning towards magnaflow...

what size tubing do you run, im thinking 3" for my 5.3

chas350 · 05-26-2009, 10:11 PM

My son has CherryBomb Vortex mufflers, they sound wicked when you get on it, but mellow at cruising rpm. Only thing, I wish they were stainless. I figure he will get maybe 3-4 years from them, but we installed them with SS band clamps so the 2.5" stainless pipe butts up to the muffler inlet/outlet instead of slipping in or over, so they will come out for replacement real easy! Nice setup. The headers are Hedman Elites with a ceramic type coating and the pipes are SS.

For a 5.3 you'll want 2.5" for duals, 3" single.

Flowmaster

UltraBlue71 · 06-01-2009, 10:00 PM

X4-5 MAGNAFLOWS!! quoting Cheech martin, "on twice pipes, man"
Not quite as loud as flowmasters, got a real deep, mellow, LUB,LUB,LUB to them.....

BAGNDRAGIT · 06-01-2009, 10:01 PM

Have flowmaster 44's, (not impressed)

Had gibson (gotta love the sound)

headed for the borlas, been good to me before....

Arad68 · 06-01-2009, 11:02 PM

Definitely Magnaflow and Flowmasters

6772owner · 06-02-2009, 09:10 AM

I would say Borla as well, had their cat back on my 06' GTO and it sounded awesome, but that coulda just been the 6.0 as well...

67chevemall · 06-02-2009, 03:47 PM

Just took Raptors of mine. They were $40 for 2 about 12 years ago. Still in great shape just sold em for $20

..no more mufflers for me.

84socal · 06-02-2009, 07:00 PM

my favorite has got to be the one my buddy mike makes

Straight pipes! Remember..... "Loud Pipes Saves Lives" Mufflers.... I don't need no stinken mufflers!

But,Sometimes A fire extinguisher is okay.

viridion · 06-03-2009, 12:07 AM

I am partial to supertrapps, lol.

'72customdeluxe · 06-03-2009, 12:11 AM

I personally think Borla xr-1's sound amazing with all of the other straight through mufflers second. Like pypes race pro, dynomax ultra flo etc. They don't mask the sound of the motor like a Flow type muffler does. They sound raw

dznucks · 06-03-2009, 08:02 AM

whats so different about spintech mufflers? i have never heard of them. just curious.

It's it comes down to personal taste. I had 40's and on my BB truck and I did not like the echo type/tinny sound...it's something you got to hear. My ears will hear sounds different than other ears. To me the spintech has a true deeper BB sound. All mufflers have qualities that make buyers prefer them. Thats just me and I am sure others will disagree. It's like colors...if we all had Green trucks our trucks would soon get boring.

ARKSTEPSIDE · 06-03-2009, 09:04 AM

For me it would be Flowmaster---I have ran them on a 65 Mercury Comet Caliente and on my 67 Chevy trk. They sound great and have good performance.They are also priced right for folks on a buget.

70 shorty · 06-03-2009, 12:28 PM

I have 50 series Flowmasters on my Vette and love them. They are not too loud, and do not have the drone of 40 series. On my truck I couldn't tell you what they are, but they are louder inside than the flowmasters, but it's got a built 6cylinder and the pipes come out right in front of the rear tires, as opposed to out the back on the Vette.

Wasted Income · 06-03-2009, 01:00 PM

Here is my favorite performance muffler....

hehe

lts70 · 06-19-2009, 01:57 PM

70cst, what spin techs are you running? Any pictures installed?

1970 Bowtie · 06-19-2009, 02:06 PM

Flowmaster IMO.

Sportsman Street Part # 3332

2 1/2 Center with offset

I had 40 series on my truck and to me they didn't sound right with my 402BB. I heard a set of Spin Techs with a BB and they seemed to have a deeper yet mellow sound. Again we all hear sounds differently which is why we have so many flavors of mufflers to choose from. I gave my 40's to a board member here...I think for free. Again...nothing wrong with Flowmasters...they just were not what I was lookin for.

They are not installed as the Circuit Rider is still a month or two away from being finished.
