Default 3" mandrel bent exhaust

Hey all! I was looking at getting this when my headers get in. Does anyone sell kits or could I just go to an exhaust shop and have them fab one up for me?

I like my magna flo's and would like to keep them. I just want to upgrade the piping before the mufflers. I have the basic magna flo kit. It's the 2.5 kit.

I went to a local shop, the guy there said it would be about $200 and some change maybe to run 3 inch from my header to my muffler, put the tips on and install an O2 bung.
This also comes from a highly recommended shop. However, it took some time. I went to 4 or 5 places before I found this one and was comfortable enough to let him work on my car (he said it would take 2 hours or so but he wanted an extra hour to be able to go through and make sure there weren't any quality issues).

Pacesetter has a kit fir the older grand prixs that will fit you would just need to replace the tips. But for 200 that's a steal. I paid over 700 for my custom setup

That's just to run the piping and put my pieces together. With the headers, mufflers and tailpipes (which i have not found yet) I'll have well over that invested.

No kidding. Just talk to some of us that are on our 4th+ exhaust setup. I have enough money in my exhaust to nearly up and buy the cartuning kit. I'm still not done. It's getting closer to where I want it but it still isn't "right".

I hear that, I'm in the same boat with how many times I've got it done.

Finally got exactly what I wanted about a month ago

It's actually very un-trucklike most of the time now.

I'd welcome some low-end torque loss.

It's one of those things that if you're going to keep modifying the car, you need to go ahead and get it out of the way. I don't have any numbers to back up my 3" exhaust.

Good luck with the 12.99 all motor.


Having said that, you can over exhaust a car but 3" isn't going to do it on a 325 cube motor spinning to 6000rpm.
