Good aftermarket exhaust system for all year round driving

[zguy]

Hello. I have 2001 GTP with about 120k miles on it. The exhaust has gotten louder over the past month or so. I just had it checked out and it needs a resonator. The local shop wants $150 plus tax to replace. I was thinking about replacing the whole system instead if one could be had for around $500 or so.

Any recommendations on what system would be good? With or without the catalytic converter? What about the down pipe?

I am guessing it would have to stainless steel to stand up to the winters here in Chicago. I appreciate the suggestions! Thanks.

Needs a resonator.

Put a glasspack in, they're $30~. Bigger the better.

This topic has been covered a million times, just look around.

Use whatever mufflers you want, the factory "Y" will be reuseable most of the time; for a downpipe, get a stainless 3" one from ZZP. Catted or catless is up to you.

glasspacks aren't as good at sound deadening as a good resonator is.

Summit has a 30" resonator for about $30... : ) and unless you're unhappy with the sound, would just replace that and leave all else alone unless you're going to mod.

"Cat-back" systems don't touch the converter, so you won't have to worry there. You'll want to leave the cat anyway because of your 01+ car.

Type of metal won't matter really, unless its cheap garbage tin foil stuff because it'll likely outlast the car.

It's all about volume of packing and if there are fins to "grab" the flow.

Most glasspacks won't have fins, and don't have much of the glass. Look for large overall diametre resonators.
