Hello everyone! I share this tip via email often when asked and want to make sure everyone knows about it

I see a lot of posts regarding an V8 Impala SS exhaust on a 3.4 or 3.8 Impala, or the 3.5/3.9 newer gens.

The 3.9 actually has the same exhaust as the V8, but the 3.4, 3.5 and 3.8 it is an upgrade, even on 3.8 Supercharged.

If you go to RockAuto and search for Walker #55525, you'll see it's an intermediate pipe for a 3.9/V8 that's 2.5" diameter, stretches from the back of the resonator all the way to the inlet of dual mufflers including the Y-pipe, and it costs only $42.

Paired with your choice of resonator or straight pipe (Walker resonator is only $42 again, and includes the flange to mate to the downpipe, and your choice of mufflers/tips, you'll have a very inexpensive exhaust upgrade!

Share and enjoy.

I Knew this as well. I wanted to try it first to see. They have it on Autozone.com when you put in the 07 Impala they have the dual exhaust piping.

OK, i about shart myself when i saw that shipping for that pipe to my crib was 58 bucks and change! i might want to source this a little closer to home. so much for exhaust on a budget, LOL peace, john
edit.... amazon has 55525 for 47.59 and it qualifies for super saver shipper free-ness! yahtzee!

Only problem I see with this though,.. is that it's only 2.5" diameter on the inlet side. It still goes down to 1.88" on the outlet side. With not having a newer bodystyle, I don't know if that is better than stock or not. Anyone ever measure? Even still, this is a VERY cheap option if you wanted to have dual exhaust. Thanks for the find!!

The 1 7/8" duals is the same as stock but that's not a problem. Together than have more surface area than the single 2.5" pipe, they're not a restriction. Buy 2" in/out mufflers.

Well,that being said...none of the locals have it in stock,and may not get it...imagine that.

So now,I'm just back to making sure that this will work with my car. (03 LS)

Thanx...I never like to feel as if I need some "hand-holding",but I'm also not too proud to admit it. So,when it comes to the exhaust and suspension with this car,I'm green as hell. Sad

thanx again for your help and patience.

local stores typically won't keep it in stock, but can have it for you in 24 hours or so, depending on the chain.

since its cheap, any thoughts and how the thrush or walker mufflers would sound with it?

I would love to grab the y-pipe, and put a HUGE resonator & 1 flowmaster muffler on it, put the flowmaster right after the resonator then straight pipe from there. think that would sound good, 2 mufflers almost seems rasp is very hard to get rid off...

So just to clarify... That Y-pipe talked about here for the '06+ WILL work with the '00-'05's hangers? It's just obviously weld connections on either end to complete?

the walker 55525 i purchased and currently sitting in ceramic paint awaiting this coming weekend for install i'm sure could be welded, but is a slip fit into the new resonator at the front, and into the new mufflers at the rear. kinda goofy as i thought the rule was for exhaust parts to fit over the piece in front of it. i can add a photo of the parts laid out on the floor if needed. peace, john

John yes please, that would be great. I think I know what you're saying, I'm just trying to get a picture as to what all I'd need to get this done. I didn't even think about a ceramic coating, it's cheap enough to lay the money out for that, good call.
I'm thinking if the resonator end is small so that it fits IN to the resonator pipe (so not correctly flowing), I'd have an exhaust shop stretch that just a bit to make it slip over the resonator.
