Thinking about a custom 3" exhaust

Mino · 06-02-2012, 08:36 PM

Hey guys I was thinking about doing a custom 3" on my Z I just got as soon as break it in at 500 miles already

. I was speaking to my muffler shop about it he said he could do it (Mike's Muffler in El Monte California) a lot of guys here know him one of the best in the SoCal. So here is my question I want to do a 3" full exhaust except oem Y pipe and cats which I will be getting some berk HFC soon. He told me he can put something together, however I was thinking about buying the mufflers myself, I have a few in mind I was wondering if any of you would recommend me one from experience. HKS hi power Carbon version, Greddy Ti-C (just mufflers) Apexi N1, or any suggestions?

Or should I just get a Agency power exhaust with the test pipes and be done with it lol.
One last question what do you guys think of a single exit instead of a duel on our cars good or bad idea? I know this one is just an opinion just want to see what you guys think.

I just saw a thread about a single turbo 370z the guy has the HKS single exit looks and sounds sick with a magnaflow 18" resonator. I am not boosted and not planning on any time soon. Do you think with a 3" single after the Y pipe I will lose too much back-pressure and actually lose power instead of again? My whole goal here is power again and weight lose, because I will be tracking the car as much as I can afford too.

Of course.. three inch exhausts are for FI. You can do it, but if u r tracking? There will be a penalty with the 3".

I will not be boosting for a while (1 year or so maybe longer) but I will be adding a few bolt-ons just to give me a little edge. I want to know without a turbo or SC with a 3" single pipe from the Y-pipe back with a HKS muffler would I lose power or I will have enough pressure?

I bought the HKS-Hi power for my car last summer. It sounds amazing. It was a little quiet for me though. AK does a pretty good review He kind of sold me on it. Last weekend I added some Berk high flow cats and wow the car sounds amazing. I have no complaints with the exhaust and have no plans for ever taking it off.

Not sure why you would do a stock Y and 3" back. You would still be restricted at the OEM y-pipe.

As far as custom shops go, you have to make sure they are mandrel bending the piping or it would be no different than going with a smaller diameter pipe since all the crush bends would lower the diameter.

Looks like your in Glendale CA. Fast Intentions is the way to go. If you are in CA, take a little ride & go talk to Tony or give him a call, He really is the man & you aren't going to find better quality or service. He's too close not to look into.

I will be changing the Y pipe later on to something bigger for sure. Because from the Y pipe back it's going to b a pretty straight pipe going to the back with a little curve to the HKS muffler and out. There is going to be a lot of free flow therefore, I was asking to see if a none boosted car would actually lose power that way or not?

And yes I know Tony and will probably go to him also before I make my final decision but I wanted to know for sure if my idea of the 3" single would lose lower or not.

To answer your question as bluntly as possible, yes, you will lose lower end torque and overall power by going with a 3" exhaust with no forced induction.

I'd be curious to here what he has to say. A single 3" has a smaller overall diameter than a dual 2.5"...

Whatever you go with, a good tune will bring you back in line.

If you do single exit, you should probably get a rear bumper that isn't shaped for two exits. I would personally tip my hat to a single exit Z as I've never seen one before.

There's a few on here. Check out O&G's Z.

Z_ealot · 06-03-2012, 05:16 PM

just my opinion, but single exit throws the whole look of the car off...not very aesthetically pleasing unless you have the bumper thats meant for it
