ok i have a flowmaster 40 series muffler on my car and had them weld the stock tip back on there. now my question is is there a silencer i can put on my car?

the reason i ask is because i have the ZZP midlength combo with a 2.5" catless dp and i deleted the stock resonator and put the flowmaster on. i didn't do much homework only to find out that a open exhaudst on a 4cylinder plus a chambered muffler equals raspyness. i hate the rasp i hear. it almost sounds like the inside of the muffler is vibrating at certain RPMs and it is driving me nuts. at first i thought i needed to wait to break in the muffler which the raspyness did kinda go away but it is still there.

does anyone have any ideas on how to fix this? i thought about getting a cat welded in but i heard some videos and the sound is still there.

 

a silencer will only make it worse. get a different exhaust.

 

welcome to the club. quieting these cars down is a mystery so far. i got two thrush turbo mufflers ready to go out (dual exhaust). if that doesnt quiet my car down, i might as well scream. ive tried everything

 

woah mike your in san antonio? lol i'll be there during spring break. i was hoping of meeting up with tyrone and rico possibly during the week sometime. i was also thinking of PMing joseph because i really want to check out his car, last time i saw it, it was still having a lot of problems with tuning and what not.

and ya tell me about it, i know the 40 series is supposed to be a loud muffler but i kinda figured it would've been deeper and no rasp. silly me lol. i think i may get the Megan muffler. or something. i have to figure something out. because i don't want a stupid fart can either. DAMN U 4 CYL!!!!!

 

weld a glasspack in where the stock resonator went, trust me.... I originally tried much the same set-up (minus the ZZP) and it sounded like raspy dog ****.... I welded a glasspack as resonator and it sounds sweet with my flowmaster

 

yeah thats cool. I really dont know anyone here since moving from corpus two years ago. IM not a car god, and usually what I like, no one else on this forum does lol. BUT i need a tune bad and the 600 i spent on hp tuners has yet to pay off for me

just cant afford 300+ to tune right now. just got car painted yesterday...blazing orange....

i agree. a 30" glasspack worked wonders for me. takes raspy out. BUT it doesnt last. It does the best of anything so far. I replaced mine with a magnaflow 4" round muffler and I regret it. sounds ridiculous now. going back to a glasspack soon

 

about how much is a glasspack resonator?
and mike you should get on the GMofSA website. there;s a bunch of cool dudes on there that are local to you with balts and some cavis in the mix.

 

i dont know what that site is?? when i got me a 30" glasspack installed...it was 75. you can buy em online for next to nothing. (20-30$). its just the cost of welding that can kill.

 

My exhuast setup = zero rasp (at all rpms), quiet while cruising, and a nice deep throaty sound at WOT.

 

got mine quieter finally! the two thrush turbos did the job. now i just need to replace the shitty 4" round magnaflow with a glasspack like I had before...and itll sound even better.

The bad thing is now I can here all kinds of other noises in my wheels, and suspension lol. things I couldnt hear cuz my exhaust was so loud. clunking,winding, u name it. ive already replaced all bushings, shocks, struts, tie rods, end links. who knows what it could be now...lol

 

hey mike here's the website and thanks for the glasspack info.
