All SSEi'* are 2.5" from the factory. From 92-present.

yea there is a member here with a green SSEi that has a Random Cat. He is the only one with the Chrome crosslace rims

??? Alot of SSEi'* have crosslace......I'm missing something here. Is he the one running dual glass-packs, too?

Just from what I have heard, the R/T Cat has thrown SES codes for many people. If that happens, you will need to get an O2 spoof.

2 1/2" Stock...I wonder if my Borla Exhaust is the same...I will assume that it is....I guess I can always go measure it.....wonder what kind of performance I will get from a High Flow vs Stock...

btw: I might need an 02 Spoof anyway....my Headers are sending an SES

the CHROME CROSSLACE

Hmm, my exhaust is very raspy after quick notes, i have currently no cat and a 80 series on there. How much would a resonator cost to put on correctly, looking to get that raspyness gone.

Go to a good, reputable exhaust shop in your area and talk resonators with them. And in the future, don't announce your lack of a cat publicly. It'* illegal, carries a hefty fine, is environmentally foul, and anyone who turns you in gets a $250 'finders fee' from the EPA. Something to think about.

I can't quote you on my Magnaflow resonator, because I paid less than cost on it, and had the install done for free at the West Coast Bonnie Fest Tech Day.

Word of warning:

To quote my exhaust guy, Jerry:

"If a car goes up on my lift and I see no Cat, it doesn't come back down"
You're in a tight spot, my friend. Good luck getting a shop to work on it now. I'd strongly suggest a dual-purpose unit. Catalytic converter (hi-flow unit) with a resonator chamber built in.

the high flow cat wont be much of a restriction if any compared to what you have now.

Performance Difference between Stock Cat and igh Flow ?
