What are the differences? A cop cited me for "modified exhaust" so now I have to go stock. California laws suck donkey balls.

You have to go totally stock? That seems like bunch. Isn't comptech--and many others, for that matter--legal in most states?

Excuse the giant picture. But there is an excellent diagram towards the bottom. Pulled this right from SurferX's Type R article (hint hint)

They are both chambered design, the TypeR muffler is for 2.25" piping where the stock gsr is smaller (1.8" I beleave?)

"The larger exhaust piping combined with a a more free-flowing muffler allowed for a 30% increase in exhaust flow efficiency."

-quoted directly from surfer's itr article (*cough cough*....in the article section)

You can get a CA vehicle code book for about $3 at DMV with all the vehicle codes in it. See what statute he wrote you a ticket for. There are certain dB requirements that an exhaust must meet; there is also a very specific process for measuring this sound level. If the officer didn't use a sound level meter, he didn't follow the process, and you should be able to beat the ticket. There was an article in SCC not too long ago stating that the measuring equipment required to enforce this law isn't even available to law enforcement. I am assuming you were cited under one of these statutes. PM me with statute you were cited for violating and I will look it up.

Whoa, California sounds like it sucks. Hehehe, sike, i mean the laws there suck. I have a question for ya that was sorta touched on by Kelly... how does the cop know what is "too loud" if he doesn't have some kind of dB measuring device with him??

Well..He got me on the 27151 code. I went to CHP to try to get it signed off but he said...."Does the muffler make more noise than the stock one?" I said yes. He then said it wasnt legal. I told him if he could Db it and he said they couldnt. He then told me to go to a muffler shop that had a db meter. wtf. cops are dicks.

I realize I might be off topic, but .... The following is from my 2000 Vehicle Code book. 27151 refers to 27150 and 27200. 27200 refers to 27206. 27200 states: "...which produces a maximum noise exceeding the applicable noise limit at a distance of 50 ft. from the centerline of travel under test procedures established by the Department of the California Highway Patrol ..." 27206 defines this limit as "After 1974... 80dBA" 27150 is vague: "...excessive or unusual noise..." But when all the references are done 80dbA at 50 ft. seems to be the defintion of excessive. The actual test procedure is not specified, but it certainly involves a sound pressure meter, etc.
The burden of proof is on the state. Your argument is that the officer didn't use the specified test procedure. He merely is assuming that your exhaust is too loud, he has to use the specified procedure to verify that your vehicle is indeed over 80 dBA.
Get the book and study all the statutes. If you do that and take it to court you will win. The statute doesn't say that if it is louder than stock it is illegal, and they can't measure it because they don't have the equipment to enforce this law.
You have to base all your arguments on the statutes. Don't discuss the matter any further with the police, you will only give them ammo to fight you with. Don't take the stand in your own defense - it won't be necessary. Go to court and observe before your trial, if you can. This is one of the few times when you have nothing to lose by pleading not guilty and going to trial; you get to ask all the questions - enjoy it!
