LegacyDan Posted December 27, 2014 Share Posted December 27, 2014 Hi guys I'm thinking of changing up my exhaust system. Current setup is: Equal length twinscroll headers and up pipe 3" Millek resonated Dp with cat in lower section Fujitsubo cat back system. Im looking to make it quieter, and maybe smaller diameter tips. So I'm wondering could I get away with going back to stock center y section with some aftermarket sti genome or similar mufflers. Anyone know how that would affect performance? I don't mind loosing a few HP to quiten things down a bit. Link to comment Share on other sites More sharing options...
spec.B452 Posted December 29, 2014 Share Posted December 29, 2014 Install a vibrant ultra quiet resonator in the midpipe, really cuts the decibels. Link to comment Share on other sites More sharing options...

fahr_side Posted December 29, 2014 Share Posted December 29, 2014 I've seen really good results with aftermarket mid / Y-pipes and stock cans. A resonator will certainly remove some of the raspy sound, if that's the issue. Obligatory '[URL="http://legacygt.com/forums/showthread.php/2008-gh8-238668.html?t=238668"]build thread[/URL]' Increased capacity to 2.7 liters, still turbo, but no longer need spark plugs.

BX77 Posted December 29, 2014 Share Posted December 29, 2014 That's what I have 3" DP, 3" MP w/ resonator and Y, Stock cans. Very happy with this set up Link to comment Share on other sites More sharing options...
LegacyDan Posted December 29, 2014 Author Share Posted December 29, 2014 Install a vibrant ultra quiet resonator in the midpipe, really cuts the decibels. I'll have to check and see if I have room for another resonator. The one in the cat back section if pretty large already. Is it better to have resonator closer to mufflers or downpipe?

spec.B452 Posted December 29, 2014 Share Posted December 29, 2014 It fits right about centered in the midpipe, but it's a little tight. As for where a theoretical best place to install it I am not sure but I would think further toward the end of the exhaust system would be best for flow purposes as it will slow the gasses exiting the exhaust a bit.

LegacyDan Posted December 29, 2014 Author Share Posted December 29, 2014 here's how it current looks, its the only pic i have or can find showing the most recent layout under there: http://i32.photobucket.com/albums/d3/desperatedano/Mobile%20Uploads/IMG_20140418_112914.jpg Link to comment Share on other sites More sharing options...
spec.B452 Posted December 29, 2014 Share Posted December 29, 2014 Looks like there is already a bullet style resonator in there, that may have to go for an ultra quiet to fit. Link to comment Share on other sites More sharing options...
