2G How can I quiet my exhaust down...

[PhatEclipseGST]

I got in trouble for my ehxaust cause Massachusetts sucks... So i gotta try to get my car sound close to stock... i have a 2.5 in exhaust and a loud muffler but my baffle doesnt really do shit... I was wondering if there was anyway to make a better baffle or if i can order suttin... Or do you think throwing a stock muffler on there would quiet it right down or is there a performance muffler out there that i can get that is really really quiet...


Appreciate anyones help

Thanks

I have the 3" inlet to the dual 2.25" outlet Magnaflow muffler. 3" Cat, Megan Downpipe and 3" RNR exhaust. I was yelled at by the police in Illinois, while I visiting for a day, about my exhaust, plus I had a leak because the RNR exhaust has a 3" flange and the Megan Downpipe neck downs to 2.5" at the exit. The 3" Cat was bolted directly to the 2.5" outlet on the downpipe and the RNR bolted to the Cat (this was a good seal).

And it was a really loud setup. I could literally hear it in my house basement from the garage. And you could feel the percussion of the exhaust on your chest (most likely from the exhaust leak). What I did to fix this problem was to order a 3" flange from RRE and two resonators a 3"x 12" and a 3" x 18" also from RRE. I took it took a reputable shop (I cannot weld) and had them cut the Downpipe at the hanger. And install the resonators and reflange it all. The mechanic decided to weld the 12" resonator infront of the Cat and after the hangers. He welded the 3" flange onto the end of the 12" resonator. Bolted the cat to the 12" Resonator. Then put the 3" RNR exhaust with flange against the Cat (this includes the O2 sensor). He then in the straight pipe to the muffler put the 18" resonator. The O2 sensor was stretched, but it fits.

The sound it makes is very nice. I noticed (probably just mentally) a slight decrease in performance from what I had before. But the exhaust is considerably quieter. You cannot hear it in the house anymore. At idle it just has a slight rumble and at WOT the noise is quite tollerable. Though ofcourse it is louder than stock. But I would think without a doubt it would pass the 50ft, 80dB at WOT law of California.

Other than the Illinois cop, I haven't had any police complain about my exhaust. I've been a prime target for window tint nazi's (in Iowa you can only have 75% tint). Not once have they mentioned the exhaust. But if anyone cares, I made it legal after spending a small fortune in fines... I fought the law and law one.. :tune:

But thats my two cents.

Yeah I am thinking about welding a resonator in there... I have a baffle in there but that is still to loud... And there is 1 asshole state trooper that gives u shit about your exhaust and not only fines you but screws you with the registry...
