I'll be running a pony down hot side, MPT-70, and intercooler with ebay cold side on my coupe in the next few weeks, as well as 42 lb injectors, and a Pro-M blow through MAF. Right now I have BBK 1-5/8" long tube headers, MAC pro chamber, and spintech pro streets with flowtubes welded on. I've heard that chambered mufflers severely limit performance on a turbo car. I was planning on buying the pony down Y-pipe and hooking my existing spintech mufflers to it. Would this be a bad idea and would it limit performance? Thanks for the help.

get rid of the chamber mufflers.. i went with HOOK MaxFlows from summit. They sound as quite a stock and they are a straight through muffler. even on the highway no drone at all very very quite untill you open it up this way it is a totall sleeper

Thanks for the tip, but I'm not necessarily concerned with the car being a sleeper. It's wild strawberry metallic with 17" chrome rims on it, 3" exhaust tips, tinted windows, and the interior from a 2004 cobra. Right now it's loud as all hell and I like it that way. I'm concerned about performance issues associated with a chambered muffler design on a turbo set up.

if you dont care about the sound then you can go with race bullets? but you will def lose power with chambered mufflers some here have picked 20hp or better when they switched to a straight through design

if noise is not a factor then a open dp is the way to go..
