Hey guys I got a catback exhaust and down pipe all 3 inch. But to me the car dosen't seem loud enough, I never really got a good look at the exhaust until I looked tonight. Is that a resonator after the rear o2, and if I cut that out and welded a straight 3inch inplace. Would I gain sound and possibly free up more of the exhaust?

yea you can definitely do that. if youre not running a muffler or resonator, ive heard a couple setups and they are great at anything under 4000 rpm, aside from full beans, then they get pretty raspy.

i say go for it, mine is the 1g srs essentially, and im eliminating the muffler for an MBRP 5" dual walled tip. i expect it to be loud, but not insane. i just hate fart cans. LOL
 
im running the srs catback and also the 3in cat and sounds pretty loud on idle but good and not ricey when driving,
 
I love my SRS. It could be a little louder though. I plan to ditch the resonator soon. Replace it with a section of straight pipe like you said.

It's a deep sounding system and has a recognizable tone it's worth the price even if you have to modify the resonator to suit your taste.

What I find weird is that the awd and the fwd versions for the 2g are different. Not just in the path they take but the size of the resonator. http://www.dsmtuners.com/threads/srs-catback-review.379135/ if you look at those pictures it is not nearly as big as mine. Yes I am FWD :ohdamn:
 
Anyone got experience with resonators? I took it to an exhaust shop and they guy showed me a smaller resonator (same 3 inch), or should I got no resonator. The exhaust has two might I add this big one and than a not so big one.
 
I must be getting old. I welcome a quiet exhaust that still performs. If the resonators are hurting performance, that's one thing. If you cutting them off solely to make the car louder, that seems like the best way ever to throw money in the trash.

If you want the loudest exhaust possible, replace the resonators and/or cats with straight pipe. The end.
 
Not sure if only califorianians get the resonators or what the deal is but my old GSX SRS was straight pipe excluding the muffler. Here is my old GSX if you want to hear:

Thats I guess opens another questions, will the resonator hurt the flow?

Thanks, did you modify the exhaust to exclude the resonators? Below is what the awd version of the exhaust looks like. Mine looks simliar except I have one huge resonator.

I doubt the resonators have anything to do with CA. That system will never pass CA smog either way.
 
Just be aware regardless of where the car is registered, in California, you can still be stopped by the police and ticketed for illegal modifications. I'm not sure how long you've been in Cali, but it's a common occurrence for the scenario I've just described to happen. Once you're issued a citation, you'll be forced to return the exhaust back to stock, as well as pay a fine. If you don't, and you're stopped again for the same offence (or have a pending fine), they can impound your vehicle.

I'm mentioning this, because you may want to rethink your decision to make your car ricer loud and attract a bunch of unwanted attention. Having a stealthy exhaust in CA is definitely a good thing.

A turbo back 3" exhaust system, even with resonators, should perform well. I highly doubt SRS installed super restrictive resonators. Even so, at your current power level, you're far from having to worry about it being restrictive. If I were you, I'd leave it be. If you're that worried about it, email SRS and inquire about the design of the resonators they use in their exhaust systems.

Appreciate the advice, yes I actually reside in CA my whole life. I just happened to pic this car up in Louisiana when I did a semester there. If there isn't any restrictions I would be glad to keep it.


Edit: If i'm not mistaken I think it has two resonators. It does drone a lot at high rpm, so I was thinking if the size was smaller it would eliminate more of it.

A resonator is designed specifically for eliminating drone. If SRS has done any R&D on the system they produce, they would have identified the proper sized resonator, and where to best place each resonator in the system in order to reduce noise in the correct frequency range. That range being the range where the car makes the most noise. Again, you would need to contact SRS to get these kind of technical details.

Assuming SRS did conduct the R&D mentioned above, you'd be best off leaving the system alone, as it should already be tuned to be as quiet as possible. So, once again, I recommend you contact SRS and ask them the questions that have been posed here before you go chopping up their system...Potentially making a mess of things.
 
There really is no drone at cruising speed, 5th gear about 65-70.

The resonators are not restrictive. They are just glass packs. They are there to cancel out the pulses of exhaust noise, ie "drone". They do their job fine.

I've lived/driven in Cali my whole life and have never been pulled over for modifications. Knocks on wood. Not to say it doesn't happen though. My brother has had his riced out Integra pulled over for loud exhaust, but he is also an idiot. Don't be an idiot and the cops will not site you for it.

Also- SR*S or Senki Revo Sport is based out of Sacramento California. About 30 miles from my house. I have their cat back and Down pipe w/cat eliminator.

I am not affiliated with the company at all. But it's local and that's fine by me. And for ebay sold parts, they are really good quality.

The way it's in the pic is basically how I got mine.

Jeeze I hope those types of laws STAY in cali. Who sits around and comes up with illegal modifcation laws? Don't they have other stuff to worry about like.. running out of water very soon? /rant

Actually, most states have laws like these. It's just that California is notorious for strictly enforcing a very robust set of statutes, especially in the larger cities like San Diego and Los Angeles. California even educates officers how to identify modifications and how to cite drivers for them. In addition, an officer can stop you solely to inspect your vehicle is he suspects it has been modified. Suffice it to say, Cali isn't a "tuner" friendly state.
 
Cali tuner culture used to be huge, since the late 90's. Ah the memories :)

The last ten years has seen almost all of the cars off the street as daily drivers. Most guys just bring out the toys on the weekends to hit the cruise. It's not as super strict as you'd think. Just follow the rules on the road and if you get caught being a jackass you are going to get cited.

We had 2 cops in our "crew" of regulars. One actually had a built 1g. He was the guy that got me into DSM's back in '99. Most of the cops are cool with mods, f*** they better they let the Harley guys blow straight pipes through town, but they are trained to look for the mods. They will do their jobs. Most of the hassle from cops seems to come from the bigger cities and people that are in the wrong place, doing the wrong thing, at the wrong time. Basically, they got caught.

Cali is strict on their auto laws and emissions but we still have the best Tuner Culture around OMG

But now I'm just tellin stories....

Later friends.
 
Yeah, we are talking about 2 completely different parts of California. My 5 year experience in SoCal was pretty much the complete opposite of what you just described. You may be able to bro it up with the local cops in smaller cities; but in a city with a million people in it, the cops could care less about shooting the $hit about all the cool mods you've done. If you are caught with a car that is illegally modified (and you WILL get caught), they will cite you, no questions asked.

I don't want this to get too far off topic, but also want to OP to consider how some of these changes to his exhaust system will affect him in the area where he lives.

Taking the performance aspect into consideration, I believe the system will perform great as-is. The resonators appear outwardly to be a straight through design, which shouldn't really hinder performance.

Sound wise, (in absence of any real technical data) I'd assume the system is probably optimized in its current configuration to be as quiet as possible. To maximize the loudness (if you wanted to do such a thing...) you would want to eliminate all resonators and/or catalytic converters with straight pipes. Pretty simple.
 
also running their catback and catless down pipe and love the way it sounds, neighbors actually commented on it saying "thank god it doesn't sound like the other neighbors civic".

So you wouldn't go with a smaller resonator? Would it make it louder if I got a smaller one?
posted some picture because someone wanted to see if there was a silencer. Not sure if these pics will do!

Have you check the back of the muffler if the silencer is there?, if it's there then it will be to quite,. Any pics of the silencer,.

My SRS has two resonators and the tip of the muffler is 5" I have no silencer and it sounds tricking good.
