99 Honda Accord EX Coupe v6 Exhaust Mufflers
Hi I'm new to the forum and I just needed some help picking out a muffler. I have a 1999 Honda Accord EX coupe v6 3.0L pretty much bone stock and I was wondering what is the inlet measurement for stock exhaust piping? They have the regualr universal muffler which is 2.4" inlet ID and a turbo version which is 3" inlet ID. I'm not sure which will fit my car. Here are some links for reference:

most of the hondas are 2.25' piping. A lot of "performance" parts start at 2.5' +, and 3' are normally for turboed engines. If you are going bigger then stock, i would suggest not going more then .25' under/over what stock is. There are adaptors for the cat back so that a 2.5' will fit a 2.25' outlet, and you can always weld it on if it doesnt direct fit bolt on. Also, N1 imo are not that good, there loud and will get u pulled over because they almost always amplified.
* i am running a varex 2.5' inlet oval muffler, they are illegal because it has a butteryfly valve to adjust the volume, but as long as u have a resonator inbetween the cat/muff and keep it under 95db you should be good. i think most laws state that 92-95db at 3500rpms WOT |

dont be ashamed to use ebay and look for mufflers, there not made as good but if your staying stock dimensions with a dual tip then you can just get a bolt on for CHEAP.
also if your having a shop weld/bolt it on for you, make sure they have j hooks incase the original bracket does not work |
I recommend Ebay. I just picked this up for $ 157.00. I plan on installing it this weekend so I can't tell you how it sounds yet. The model I picked up is sold out but there are some similar set ups for about the same price as long as you don't live in Cali. you should be fine.

ANYTHING in California has to have CARB certification. Even an identical muffler where the manufacturer hasn't gone through the official certification process would be illegal there.

That narrows down your options and because of the required CARB certifications it means you are going to pay at least double for just about any modifications you want to do.

If it were me, I would go with Magnaflow or Vibrant Performance mufflers......pick out which style you like, and take it to an exhaust shop, and have them bend and weld up piping. Those Megan canister style exhausts tend to drone a lot at highway speeds, and are generally pretty loud, and even raspy. Magnaflows however, have a very refined sound, and are quieter.....= Less attention from cops. Its also a higher quality product.
You're OEM piping will most likely be too small, and no matter what, you will have to change you're overall exhaust piping diameter. |
The shop I ordered the exhaust from said they had a damaged shipment from the manufacturer and won't be receiving a replacement until some time this week. Can't complain to much they offered to refund my money or give me a 10% discount for the wait. I took the discount.

hope w/e u order is CARB accepted since u live in cali. + u will have a nice little sticker lol to show when u get the car inspected. same deal with intakes, california sucks for emissions

Do it once, do it right. You'll end up spending less money in the long run, and there is nothing like knowing that your car is built with quality parts. |

Currently, I have the stock exhaust. I'm just waiting to smog the car again before I change it out. I'm planning on going with a Magnaflow dual tip muffler with custom piping.
Listening to videos again, I definitely think the Magnaflow will be the best sounding choice. Its nice and rumbly. If you want it louder, you can always remove the resonator. |

The argument can be made that you will lose power, especially in the mid range, by increasing the piping size to 2.5".
