Dang guys no need to punish me for a question. I make plenty of money, that's not the issue. I'm just the type of person that doesn't see the reason in spending over a grand for an exhaust that gives you the same power gains as the system that's half the price. I took the specs from the stillen g3 intake and made my own with the same gains give or take like 3 hp. Cost me about 200. Rather than almost 600. I'll take that any day. I understand the quality part of it all. But when you sit back and look at it, it's air going through pipes. As long as the pipes are mandrel bent and the sizes are similar along with the piping position, shouldn't it react the same as all the others? Please correct me if I'm wrong, I'm a smart guy but I'm no genius nor am I am expert in exhaust systems.

Yeah I was looking into a couple of those, the top speed would be my strongest choice only because the research I've done and with the shops I've talked to. They say that once you go into a single midpipe and take away the x pipe that you lose about 10hp in the long run. I live down here in south Texas and I go to Jtran motorsports alot. The main shop owner knows a crap load more than I do and deals with these cars on a daily basis. I already made some short tails of my own but I'm kind of stuck on what I should do from the catback.either just replace the whole system or piece together my own. I'm going with non resonated test pipes for sure tho. Any ideas on making my own?

I'd suggest researching up on quality exhaust shops in your area who would be willing to do a custom one. I'm all about saving money when you can but I'd stay away from the Ebay junk like Beluga. You can always browse the FS section and look for good deals there.

There is a reason why a lot of people go with a quality system though. They are proven, backed up by lots of testing, and the sellers provide quality customer service. A lot of people don't consider the last one, but it's the most important to me. You might have saved $500 on that cheap exhaust you purchased but when it's missing some hardware or doesn't line up properly and they don't answer your calls because they already have your money, you are screwed.

:tup:

Exactly. Don't get bullied by the forumites, who generally mean well, but not everyone is in the market for $1000+ exhaust systems. There are many reputable discount exhausts for the 370z if you do your homework. Do a forum search and you will hear many good things about Beluga, CNT and Garageline exhausts.

Thanks man I'll do a little research and see what I come up with. In the mean time any links that you guys might have would be helpful.

What are the worms when swapping out the oem cats?

demon bolts. Do a search on here and you'll understand.

Here is a picture of what it tools I used to get the cats off. That short bolt is a snapped bolt.

I don't think you understand the issue. It seems that OP doesn't have the problem of wanting to buy a less expensive part because he cannot afford it. He is looking for the cheapest way to get what he wants. There is nothing wrong with that, and I share that mentality with him. Why would I spend $1200 when I could spend $500 and be just as happy? Impressing people on the internet or at a car show over how much I spent doesn't appeal to me, perhaps it does to others and that's their prerogative and there is nothing wrong with it.

After all, I bought the Z over a Cayman because it was a "cheap" way to get a good looking fun sports car with decent amenities, yet I don't see you lot telling me I should have just bought the quality car.

I would like us to move forward and just help the Op with his question instead of lecturing him.

At this point he is doing nothing wrong with just finding a low cost solution that is NOT endangering him or anyone else.

Op,

There are some options on here as some have pointed out.

I would just make sure they hold up in time and not turn to crap after a long period of usage.

the quote of mine that you're referring to (in a bit of a douche way fyi) was said PRIOR to the OP saying it's not about money.

I said what I said based on precedent. typically 90% of the people who pose this question/idea about cheap parts is doing it because they can't afford them. hence why I said what I said. furthermore, if you had more then 30 posts you'd probably realize the running jokes about people poorly doing DIY parts and the jokes that follow.

When I had my Z I had the stock Nismo exhaust with tanabe replica axle back(made by top speed) and top speed test pipes. Got nothing but compliments on my exhaust from random people on the street.

Oh, there's a few...

1. The aptly nick-named "demon bolts", as another member noted.

2. Unforgiving rasp and rattle on decel (if unresonated TP's are used).

3. The potential for a CEL if the ECU detects too much similarity in voltage changes between primary and secondary O2's.

4. Passing emissions, if that's a thing in your state; (NB: #3 and #4 are both possible problems even with HFC's, and resonated HFC's are advised as well...)

5. Possible fuel odors (probably more for those running TP's untuned...)

6. A tune is not "required" but is highly advisable. Pulling the cats makes for significant differences in flow and also means less heat at the head, so you can dial in more timing -- the OEM cats are arguably the greatest bottleneck on the car, and swapping the cats out for either HFC's or TP's is a high bang-for-the-buck mod in terms of power gain.

Nothing insurmountable, but not quite as easy as just swapping out the cat back and calling it a day.

Thank you for clarifying sir. I was going to buy a c6 z06, but just wanted to keep it simple about about 20 grand cheaper haha. When I can just put about half the money difference in the z and be faster. I have always be a fan of the z family so the choice was a no brainer for me.

Yeah I was doing a little research on all the issues with hfc and test pipes resonated and non resonated. I wanted to do my own set up with 2.5 inch all the way back with x pipe and about 18 inch resonators in the midpipe area with top speed axle back exhaust. I'm thinking about testing that out to see how it sounds, and then I'm going with the obvious tune, uprev
