    I'm not sure if this company makes an exhaust for your particular vehicle but strictly for sound I really like ANSA systems.


  • I currently have the Greddy SP2 Exhaust on my car and i was thinking about purchasing the Blitz Nur Spec exhaust and was wondering if anybody knew how it sounded on this car or if they know that it sounds good with this vehicle and i was also wondering if i put headers and a down pipe on the car will it make a big difference in the way the exhaust sounds therefore i wont have to change it please write back if you have any suggestions or if you konow thanko you

    Will cutting off the catalytic converter help give my car more power. It is a 1997 honda civic dx. I would like to find any web links where i can see where i could and how to get it done.

    I think you'd be much smarter to install a high-flow catalytic converter. Taking yours off has unpredictable results since your car's engine management system may be linked to your catalytic and cause possible loss of power, increased fuel consumption and the engine light to stay on all the time.

    A high-flow cat with cat back exhaust might give you something like 8-12HP total.

    Also as you may know, removing your catalytic is totally illegal.

    I have a 2004 Cavalier LS Sport. I work for my Dad who is a small dealer and we bought it with the intention to sell but after driving the car for awhile I decided I'd buy it. When we bought it it already had a cold air intake and headers. The previous owners also had put in a cat back exhaust but with no muffler. Needless to say, it was soooo loud. So we took it to the muffler shop and got a magnaflow performance muffler on it and that made it much quieter and acceptable. But as I've driven it more it's either gotten louder or I just forgot how loud it used to be, but either way I am annoyed with the noise, mainly on the highway at high speeds. So I've been looking for ways to quiet it down and I read about resonators. My plan is to get a resonator installed somewhere between the converter and muffler, and maybe get an exhaust tip that is also a resonator. While they're welding things I thought I might as well throw in a high flow cat and see if that would help my power at all. My question is: The high flow cat has no sensor socket. The resonator does. If I plugged the sensor into the resonator which would be down the pipe a bit, would it still pass emissions like it should? Would I be risking that or getting a check engine light? I don't know much when it comes to exhaust and things. Please help and sorry for the long story.

    That sounds like a question that could only be answered by experiment. There are too many variables I think to make a prediction as to what would happen. I wonder why the high flow cat has no sensor socket?


  • Hello, i have a 5.0 88 tbird only thing added to it was flowmaster exhaust was wonder how much hp / torque that adds plus how to make it fast n quick and does anyone know how much this car weighs
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,403
    I depends a lot on the car but probably no more than 8-12 HP.

    There are tons of things you can do to that engine. Time for some homework to plan your project!

    Here's a book you might enjoy looking at. It's cheap from Amazon: It also lists other books you might find helpful.

    Engine Tuning 5.0 Liter



  • I have to replace my stock 2001 MDX muffler & exhaust due to car accident. Is there a replacement aftermarket that will improve performance either HP or fuel economy.
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,403
    I think only if you use a free flow catalytic. If you just attach pipes to your existing catalytic, I think you'll get more noise and very little HP.

    Again, you have to think of your car's engine as part of a LONG pipe...starting from the air intake to the air filter and ending at the tailpipe. If you don't do stuff in the middle, doing things at either end really can't alter the situation a great deal....a little but not much if you look at it this way.


  • Hey guys,

    As known with the 5.4s I have exhaust manifold problems/ w/studs. The passenger's side has a crack in it and the drivers side needs to be removed, magnafluxed/planed and put back on. Should I replace them with headers or replace/repair/ the stock ones. If headers are the trick, what about sensors and stuff- one hypo shop says they aren't an issue, but a Ford dealer says my engine light would be onall the time (Ford dealer I believe was assuming). One guy told me to keep stock remove the muffler and run straight back off the cat. (sounds gay)Should I take out the y-pipe and run duals to the back? What has someone tried and figured out before I spend time and money with this thing- I want to get more HP out of it if the price is all the same. Am swapping in a Airaid air intake system too.
  • Hey can anyone help me find a company that makes a performance intake or a universal do it your self kit for my 1986 325? I have checked all the main companies like k&n, AEM, Injen ect. and have had no luck. Any help would be great. Thanks Dan.

    try these guys:


  • Wow, holy crap man these guys have everything! Thank you for the really big help. :)
  • I've got a 2005 v6 Mustang with a JBA Dual exit exhaust. I can't stand the way it sounds now. It is loud and sounds like sport compact. Is there any way I can get it to hum like a V8 or am I dreaming?
  • Hey i need to know what is the best type of header to get for my car, also what would be a great way to get the most HP gain for my car. I have a 2001 Honda Civic Ex 1.7L SOHC Vtech with a short ram AEM cold air intake and a Full Exhaust system. Im wondering what the best type of header with the most power gain. Is there anything else i should invest my money into to get more power.

    Thanks :D
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,403
    Maybe a set of Flowmasters with a diameter equal to the diameter of stock but a flow-through design. I don't think you'll quite get the pulse of a V8 but you might get rid of the fartcan sound.


  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,403
    I think if you are going to go into a full intake header than you'll need to upgrade the engine internals to some extent.

    Think of your system as ONE LONG can open one end and then the other end but as you can see, if you don't do something to the middle, the returns diminish rapidly no matter how much you spend opening the ends.

    I don't know enough to advise you on how you might cam this motor but you need to think this out in terms of a total process...if you are putting more and more air into the engine then you need more fuel to get more power. The only real "power" in air is if you turbocharge, and even there you'll need intercooling and bigger injectors to tame all that hot air.

    I'm sure the many vtec boards have figured all this out.

    Does anyone here know where I can find tuning products for the '05 5.7L HEMI?

    I am looking particularly for headers and a supercharger and possibly a way to disable the governor's chip? I top out at around 110/115? I am fairly new to this so looking for all the help i can get to make my JGC as quick as possible (I got the 5.7L cause I wanted the tow package just in case (I live in PA) otherwise I would have got an SRT-8) But it is nice to take off the emblems on the back and watch the rice-burners cry

    Currently I have:
    AIR-AID Mass/Cold air intake w/tube
    BORLA Cat-back exhaust
    JET Stage-1 Chip
