Straight pipes, 9 times out of 10, sound like absolute s**t!

Glasspacks, 8 times out of 10, sound like absolute s**t!

JMHO of course.

If you've got the power, a nice single chamber race-series muffler sounds good. If it's more of a stock, or mild engine...then a dual chamber race-series muffler sounds good on it.


A buddy of mine has a '79 F250 with the 351M in it. I talked him into the Goerlich VR7426's (2.5" single chamber race mufflers), and he loves it. It is hung about 3 feet back from the stock Y-pipe.

(Performance-Curve on Ebay has them for $32)

I put two on my '78, behind the 466ci. They sound awesome!!

 

Yeah i live in Salvisa, I just usually tell people Mercer co. or Harrodsburg cause no body knows where Salvisa is.

 

i have 2 1/2 straight pipes on my 1990 f250 with a 351w and i love the sound, they are run straight back to the bumper and you can barely hear them from the cab, but when she dives by they sound amazing!

 

As long as you take the pipes out the back you shouldn't have too much issue with noise in the cab but a couple glass packs definitely wouldn't hurt the noise or the back pressure issues

 

I like the straight-pipe sound, but I can see that it could definitely get old. I have long tube headers, true dual 2.5" pipes, and Flowmaster 50s behind my 460, and it's not too loud or droning for daily driving. I plan on putting some dumps in a little past the headers, so when I'm in the country and want to enjoy some noise I can, but I (and others with me) don't have to worry with the noise all the time.

 

It's all a matter of opinion. On a gasser? Straight pipe = no no. Loud, sounds like ****, etc. If you want louder get yourself a short little glasspack or, like suggested above, a little race muffler. If you want some deep throaty sound, get a long glasspack.

 

I can see the "wanna-be heard" thinking. I dont want the local police to know I was coming a mile away. I had THRUSH ( others avail ) flo-thru glaspaks that cut the sound great without restricting OR redirecting the exhaust flow. They were true flow-through ( straight pipe with holes inside and 6"x 33" sized body ) > NOT chambered like some others < I also went with 1/2" larger pipe AND used 3" x 24" tips that used to be air (pneumatic) cylinders. The tips deepened the tone and were better stainless steel than most "stainless steel" tips.

 

Well I guess I can throw a post in this thread now. I went and visited my mom in the next town over. I have straight pipes and it was rattling my head (I just took up the dynamat and carpet). I was kinda pissy when I got back home for 2 reasons. I got a ticket and a head ache. My word of advice, put series 40s on it and put down dynamat and carpet and it really helps with the sound on the inside of the cab. No one likes migraines and 75 dollar tickets...

 

If it's a "built" motor straight pipes can sound pretty bada$$, on a stock motor not so much.

But i'd still muffle the sound a bit with at least 18"-24" glasspacks, just to keep the boys in blue at bay.

 

Yea my engine isn't BUILT but it has some umph to it. The Leo's aren't big fans of my exhaust set up.

 

hey we revived an old thread. My glasspacks are plenty for my poor ears. Plus the coppers can't say anything because I do have mufflers. Now I'm just waiting to get my behind cab exit

 

When I had the 351M, I did the RV cam and intake swap. The year before I yanked the cast iron exhaust manifolds and put on headers with 31in glass packs. Loved it!! And the best part was I had dudes asking me if it had a 390. THAT was funny!
Im running some cheap turbo mufflers right now, but Im really thinking about cutting them off and going back to the glass packs. As for straight pipes.....do what you think sounds good. Also think too, that if a Harley (no offense to the bikers!), can run straight pipes (and I know most do) why cant a truck?? Same goes for the ricers with the fart cans....some of those little cars get pretty darn loud. So yeah.....un cork that baby and have some fun. Maybe I'll take the bolts off the collectors for a couple of days and terrorize the town....

 

My dad used to have a 750 Kawasaki Vulcan that he straight piped, and holy crap you could hear that thing coming from a mile away

And the cops didnt harrass him??

 

Nope. 5 years commuting pretty much every day, only got stopped a few times, and never any tickets.
