on the pic .hehe dont think a pic of my levis would go over too well with the moderator.i have hardly any drone with the 3 in super turbos. i think that the 21/2 in super turbos would solve that.talked with hib today and he said the reason gm put in the second balance pipe (h pipe)was to smooth the exhaust note in the back of the car where the resonance was comming from . i understand wanting to hear those costly horses but what i find more satisfying . is for them to think my car being so quiet its an easy beat . then they see my bumper and their mind gets blown. plus there is the added benifit of the cops not turning around when they hear my car go by . the second balance tube sounds like something worth doing . i dont have any experience with what the single opening super turbos would sound like on our cars . since the 90-1 zr1s had 4 exhaust tips thats where i went because i wanted the sysem to look totally factory stk.


Can you do paragraphs? would be easier to read, you say they make dual outlet super turbos for the ZR1?

I rather not be too quiet The LTx muffs are choking my car for sure 25- 30 horses? who knows.... I can feel it holding the revs back,

I realize I'd rather bark a little, and I mean a little than to bite....but with freeer flowing muffs, bites are gonna hurt big time.....
hi i am sorry its tough to read .but i am a computor rookie and i take forever to eve n type . so please bear with me .the super turbo muffler i bought were universal . i welded them on as well as the tips . you might ck your exhaust to see that it is centered in the tunnel and that you have a minimum of 10 mm of clearence between the rear end and the exhaust as well as the tips and the rear valance . if yours is bolted together you might also see if you can extend the tips out past the end of the valance a little more .one last thing that just came to mind. ck to seetheat where the exhaustis hanging on the hangers *(the 2 sets of springy things)that bolt to the exhaust on the way back if they springs dont have any tension on them that could be the sourse of reasonance in your car as then the exhaust is hanging bythe connections on the motor and the rear hangers. that can turn your exhaust into a tuning fork . reasonace is caused by vibration believe it or not . which is why gm put all that engineering into those hangers . believe me if they could have built the car without them they would have and over the course of the c4 build saved millions of dollars oh if your car is 92 or later you could get the super turbos that have a single outlet and weld the tip on to the new muffler
