Since there is an exhaust thread pretty much every other day, I thought it would be good to make one for those looking to make their own custom exhaust. Many people tend to go this way because the aftermarket systems for our cars are becoming more and more difficult to find. Let's begin?
What size piping would be best for my GT/ST//GT4/etc? This question really depends on your goals for the car, and what you do with it. My typical rule of thumb that has worked best for me, is 2.5" and below for N/A vehicles, and 3"-3.5" for turbo'd vehicles. The bigger the piping on an N/A, the more bottom end you will lose, however, you will gain better top end. Find your trade off point. What about mufflers? This is where it gets interesting. The muffler you use will determine how your car sounds. There are many different ones out there, and different types. You can have the traditional canisters, which you see mainly in the tuner scene, then there's the Magnaflow/Flowmaster type. Here are pictures showing each: Canister: Flowmaster/Magnaflow: The difference in these mufflers comes from inside. Quality mufflers will have better construction and better quality inside baffling, which will bring out nice sound from your exhaust. Cheap mufflers like the ones you see on Ebay will use sound metallic and tacky. My personal recommendation if you choose to get a canister would be either the Megan Racing N1 replica ($70-$80 on Ebay), or the OBX B10 ($50-$60 on Ebay). How do I get the piping? Now here comes the fun part. After you've purchased your muffler and decided on your piping size, you get the piping itself. You can buy DIY exhaust kits online, which are fine if you know how to weld, but otherwise I recommend going to a local exhaust shop. From here, you can tell them what you're wanting out of your exhaust system, plus you can customize your muffler placement/angle, as well as the design of the piping, so that you can get the most straight piping possible for your setup. I paid $130 for 2.5" piping on my Supra, this included the piping itself, a resonator, and the labor to put everything on. You will want to get piping from the cat to the back of the car. Basically they cut the piping off from where it runs into your cat, and then weld on bigger piping. Many exhaust shops will NOT condone the removing of your cat, nor do I condone it. This brings problems with emissions, as well as state inspections, not to mention your car will sound like crap. I highly recommend getting a resonator added in with your piping to ensure a better sounding exhaust, you'll be glad you did it. Here is my final result with my Supra: I hope this will give you guys a better understanding on what to look for and get when wanting to get an exhaust system. -Matt This post has been edited by GotToyota: Aug 26, 2008 - 9:44 PM |

Niceee post!
Dont forget the Greedy (or replicas like OBX) SP2 muffler used by many owners 6gc! Some blabla... QUOTE The GReddy SP2 Catback Exhaust Systems are 2nd-generation exhaust systems based on GReddy's famous SP catback system series. The GReddy SP2 (Street Performance) Catback Exhaust system continues GReddy's tradition of high-quality performance exhaust systems.
Through customer feedback, GReddy redesigned the SP2 catback exhaust as a full stainless steel catback exhaust system that is similarly priced to the original GReddy SP exhaust system. The new GReddy SP2 catback exhaust features a SUS304 stainless steel muffler canister with extra strong SUS430 stainless-steel end caps that feature a deep, high polish. Manufactured using state-of-the-art robotic seam welding, the single-wall canister of each GReddy SP2 catback exhaust features increased rigidity for maximum durability and life. The new GReddy SP2 catback exhaust system also features thick walled (1.5mm), polished SUS304 stainless steel mandrel bent piping for better resonance and vibration control and enhanced corrosion resistance and durability. New lightweight, flared and stamped stainless steel flanges are also used to provide improved sealing characteristics. With over 35 types of internal perforated tubes, each GReddy SP2 catback exhaust system is specifically tuned for the best combination of sound and performance. The large, high volume GReddy SP2 exhaust muffler provides maximum exhaust flow with a deep, pleasing tone. The GReddy SP2 catback exhaust is especially effective when used on vehicles with an aftermarket turbocharger system. The unique outer-curled oval exhaust tip is embossed with the famous GReddy logo. Most GReddy SP2 exhaust systems are complete catback units, which do not effect emission related hardware. Each GReddy SP2 catback exhaust system is designed for a specific car application and can be bolted on out of the box, using factory mounting hangers.

Yeah, you got a point. Everyday I see some question about exhaust in regards to piping size and mufflers. It would be nice to have a reference so people can just go right to it.

I just got the obx muffler put on last week. I did not get larger piping from the catback because it sounds exactly like the stock muffler did. I think i will upgrade to the apexi n1 universal muffler and get 2.5 inch piping done. So i hope after that it will sound decent.

I NEVER recommend welding a new muffler onto the stock piping, you will NOT see any benefits (other then sound, if you consider that one).

I know you did not recomend it but i told the muffler shop what i wanted and they just welded it on to stock. But i did not get any sound diffrence from stock with the obx. It sounds like a prius lol. But i am thinking about going with this http://cgi.ebay.com/ebaymotors/ws/eBayISAP...rksid=p3907.m29 and get 2.5 inch cpiping from the ccatback..and watch as they do it this time. I think it will be diffrent i have never seen a black muffler and i think it will look pretty cool with my black celi. AND thanks for emailing that guy gotToyota..i did not mean to "shoot" the messanger.

You can go with that muffler, but you'll be getting the same results as with the OBX. IMO, it's not worth the extra $150 dollars just for a genuine Apexi. Go back to the exhaust shop, tell them you want to keep the OBX muffler, but just want 2.5" catback piping put on.

what if i went catless and got a resonater? Don't go catless. Get the 2.5" piping, and a resonator. If you go catless, regardless of the resonator, you will have a VERY raspy sound and not pass emissions. EDIT: Nevermind on the emissions, I see you're from Florida. Oh well, you'll still sound like crap. This post has been edited by GotToyota: Aug 26, 2008 - 10:26 PM |
