Just got my Spintech with 4in pipe installed on my SS with Pacesetter LTs, and holy sh*t! This thing sounds ungodly mean. very deep tone, nice rumble at idle, WOT scares every child and animal in a 3 miles radius (well, not exactly but you get it) Couldnt be happier. Sound pics will come as soon as i get the new clutch to work right....

thats good to hear. I had the 3" muffler myself and was pleased with how it sounded. It was not loud at all though, really quite.

 

is it the dual outlet spintech or the single outlet?? I am thinking of going with the 4" Mufflex with the spintech dual outlet muffler. Post up pics

 

its the dual outlet with 4 in pipes. At wide open throttle, this will hurt your ears if you are behind it, no ****. Ill have some clips up asap so u can hear it. Very happy with the fit as well as the sound.

i got the 4 inch mufflex and everyone says its the best sounding ls1 at the track

 

hey this is john from last night in the black zo6. i heard his car...trust me...BADASS...and this is coming from a guy that has 3" true duals. i actually found this post from doing a search on mufflex. im thinking of switching. by the way, i think i like it better than my buddies GMMG.

 

I was thinking of getting this exhaust but can't make up my mind between this one and GMMG.How much did the system cost?

 

thanks man...\\



now tranny go boom

 

Looks like mufflex sells it for around 600 or so. I lucked out on mine and got that and a custom ypipe for 450 installed. Shop around, prolly get it cheaper from a vendor. definatly worth the cash when u hear it!

Ive been running a spin tech on mine since 2000 or so and I love it...I could stand to be a little louder, but I think that has more to do with the Cats than anything. Changing to the "race" series may also help, but I like the way it sounds.

 

I have buddies with the 4" and 3" and both sound amazing...Glad you like it.

BTW If anyone wants a 4" mufflex muffler only let me know, I have a BRAND NEW one I will sale.

Can't wait to hear it and see some pics!

 

any performance gains or just sounds bad *** lol

 

spintechs rock, I get compliments daily on the way my sound,,, I probably keep getting these mufflers as long as I have an ls type vehicle.

 

do you guys prefer the 4" flowmaster or the 4" spintech w/ 3.5" tailpipes?

 

The general concensus is that flowmaster is a no-no on 4th gen f-bods so id say go Spintech. As far as powergains, i have the catback and the LTs put on at the same time, so yes i experienced power gain, but how much to attribute to the Spintech, i dont know for sure. However, the guy that used this system before me, said he only lost 3-8hp over a cutout! Not bad

The Flowmaster 40 series race mufflers are a good flowing muffler they just have one in and out though. As for the Spintech performance they say that there are great gains if you need that big of a system (4")? I made great power through my Corsa 3.5" and it was really smaller than that if you measure the point where the Y meets the exhaust like 2 7/8" so take that for what it is worth I ordered my Mufflex over a month ago and still have not recieved it so if you want one better get it orderd so you can wait etc... Glad you like it Justin!

 

I have heard this exhaust, very nice sound and great performance. Was my favorite until I found the wonder that is GMMG.

 

I too have the Mufflex 4inch w/ the single SpinTech 4inch out.. i love it.

 

bringing this one back up, any pics yet?? I have a GMMG on the car right now, looking into the 4" mufflex dual outlet.

 

So where's the clips?

edit: remember you can send the clips over to LS1Sounds.com
