Exhaust upgrade
so I've been wanting to upgrade my exhaust on my 89. I do live in cali so if I go with dual I'll have to switch it out every 2 years for emissions. Was thinking about the corsa system but it's still a y pipe exhaust. So I'm thinking dual exhaust. This is what I'm looking at.

I want to go with stainless steel. Don't want to play the LT1 conversion game either. Someone near me wants $350 for one from a 95 which seems high to me. My motor has most of the upgrades you could do to a tpi. Just want to get rid of the last big restriction.

Performance upgrade and better sound. I was thinking of maybe going with the dual exhaust. And then bolting up the borla axle back exhaust part number 11134. Currently have stock exhaust with flow masters. I prefer to install this myself. I doubt any exhaust shop in California will do the modification I want.

I figured since my motor has a zz4 cam, flat top pistons, AFR 180 heads, ported intake and plenum, AS&M runners that dual would be better. My original plan was to replace the front y with catless which I bought but is on backorder. And get a cat back system like a corsa system. I wouldn't mind doing headers but that would be a pain to change out for California smog test.

Hey Kitt just do a 2.5"Y catback you wont notice any power gain vs hassle its not worth it.
Pretty sure the main pipe is 3" its been awhile
On headers its possible to tweak some LT1s (dougs) that have an EO#;technically not "legal" but close, havent seen anyone get turned away using them
elis2cents has an LT1 exh if you want, hes local and wants nowhere near that kind of $

Well if I really want to go with headers. I've pretty much considered melrose. I read on another thread that someone had a y pipe made for them to retain the stock style exhaust. I sent them an email to see what they say.
