No. It's 1.5 inches more piping. You should be good.

So let's assume my piping is all okay, would I be able to fit the tips near flush with my CS rear?

The best way to gauge that would be to see how the OEM exhaust sits on the CS rear. From there, if your piping turns out to be good, which I doubt but you never know, your tips should sit with the burnt part showing a bit. However, the most likely scenario is you will need a small extension to get them to sit nicely. IIRC, the CS rear has a built in diffuser correct? That will most likely make the tips sit tucked :/ hopefully not though. See if you can find a picture of the CS/OEM exhaust combo and post it up for comparison. Either that or contact Jayk/Silencer_0 and ask them this question. Both of them ran a CS rear with a MD exhaust. They would know best.

That's how my OEM is right now. As you can see my tips are crazily tucked in. I've seen some MD exhaust sit more tucked than OEM. Which is really weird

let me know how urs sounds when you put it on. Mine sounds a little wierd but im thinking it just needs time to break it..

edit: btw I went with the rolled for the win.

yea you def. need to break them in. I won't be putting them on for another 2-3 weeks. Im shipping back my straight tips and they will send the rolled tips at no charge. I'm not sure if they will cover the shipping on my end. Idk how this will work. The box that the tips came in, do I just put it back in there and go to FedEx and say the company is covering for the shipping?

Depends of if you are just changing ur mind on the tips, then you should pay shipping. If they sent you the wrong ones, talk to tony and I am sure he will give you a fedex number to charge the shipping to. Btw when i took the tips out of the box i was like holy **** these things are as big as my face, but they look totally normal on the car!

Edit: just re-read the main post, since hes already swapping them at not cost for you, Id pay for the shipping.

Well I originally wanted rolled tips. I'm sure they have an RMA number. Just sucks that I'd have to wait 2-3 weeks :/
After I waited 2 months for the exhaust :/

We both know what 2-3 weeks means. I would just put it on with the straight ones now and buy another set, its what $60?

i wish
100 a piece
I'm just wait more and save 200
