Our 2007 Base 2.4L Sky has the standard single exhaust tip as shown.
115990

If I replace it with a stock dual exhaust from a Redline, will it be significantly louder? I want the look but am concerned the exhaust sound will increase. We simply joyride out on country roads so "louder" is not desired.

Lots of people have done this conversion and I have never seen one complain about added noise. But if its not to your liking, Solo sells a variety of mufflers that provide from little to a lot of happy sounds. Its easy to make it as quiet or loud as you want.

It will be noticeably, but in my opinion not "significantly", louder. I have the RL exhaust on mine and like the sound.

If you just want the look, get Glenn to send you a tip cut from a take-off exhaust, make a bracket, and attach it to the end of your muffler.

I have a R/L valance for sale....100 dollars plus shipping from zip 34135....Bonita Springs, Fl. Here is a tip, u do not need to change to a R/L muffler per say. All u do is purchase a muffler with dual outlets and have it welded on where your original muffler is...u can select which tips u want...and that is also welded on....that's it. That's what we did in the old days....and listen, many owners gave there R/L mufflers away, gratis. I am sure someone has one to give away.

This method saves you all the hassle from a catback. No extension pipes.

Even the stock dual exhaust is not loud. I mean, I also own a V8 Firebird with very open exhaust and that is measureably louder at all times (loud but good :) ). The turbo 4 is really quiet even at full power. IMO.

The turbo itself acts as a bit of s silencer when the exhaust gasses go through it so they can get away with a bit less restriction in the mufflers, but I haven't heard of anyone complaining when they do the conversion you propose.

You could always do what somebody had done to one of my cars - see below - they simply hung a second muffler tip set connected to a pipe going nowhere, on the other side of the car, no doubt to try and make it look like a V8 powered car (the tips on the right are dummies). You'd have the sound of your stock system, the look of the Redline and less expense by not needing to buy a new system or even muffler.

I am not into "fake". I want it real, just not louder. A tad bit louder would be acceptable but not to affect our conversations, top-up or top-down.

I want a stock Redline exhaust system, unmodified. There is a Redline exhaust system for sale locally. Is this system missing a cat? It looks like a simple pipe was spliced into the system. If this is an unmodified complete system, is this a direct bolt-off, bolt-on process?

The cat is oriented vertically, next to the engine. What is in your pictures is what is referred to as a cat-back exhaust, and will directly replace the one currently under your car.

Thanks for the clarity on the cat.
Are all the joints in this system typical of a Redline?
Does every Redline have the dent seen between joints?

My memory tells me that mine have the dent, but I will have to look at one to confirm.

My exhaust does not have the shiny tube over the pipe about 1 foot before the muffler, IDK what that is. Maybe just a heat sheild.

Is the pipe diameter the same between the turbo and NA? I doubt it'll be noticeably louder. It's sports car..... It should sound like one. :)

The pipes are the essentially the same. The mufflers are different. And it is noticeably louder.

My experience was that is only somewhat louder - but noticeably deeper. I'd recommend doing it.

Thanks for your opinion.

Based on everyone's comments, I think I would do it if I find "The Deal" locally to drive over, pay cash, and take-home. Shipping of anything involved would make it too expensive for me. Time is on my side as I am not in any hurry.

The local one isn't available any more?

Things may have changed since two years ago. But I purchased the dual exhaust at gmpartsdirect.com for $1100 and purchased a redline rear valance on ebay for $300. Installation at Minute Muffler was only $220.

If the exhaust is not a discontinued part and if gmpartsdirect.com can ship it to a muffler shop - it's not much money.

Ah, But yes. Do a real muffler shop - not your local mechanic. Becauise they might have to heat it and bend it to make it fix exact.
