custom y-pipe
it seems like axel backs work well for our car for hp gains as upposed to cat backs. could this be because of the stock ypipe being restrictive? it looks restrictive when looked at or is it just because our pipes get smaller diameter after ypipe or are the back mufflers that restrictive im wondering because i cuold save a lot of money just buying a different ypipe joint and welding it in and removing the stock one. since ive already removed the resonator and mid muffler i like the noise and i want it to be even louder =) ypipe and back mufflers is what im looking at next

Here's what it sounds like if you're going full straight pipes after the cat.

The mufflers are only part of the issue. All the piping needs to be replaced. No sense in just the Y. Look at the pipe before the Y. Its flattened out some and more of a flat bottomed oval. If your going to replace the Y might as well have a shop replace all the pipe from the cat back with something larger. Stock is only 2" on the TL-P and 2.25 on the S.
