Exhaust resonators?

[skwerl]

Time for a dumb question, guys. I don't know of any good local shops so I'm asking here.

With the new engine and Hot Rod cams, my car is much louder than before. I'm running stock exhaust except for cat deletes and it used to sound nice and mellow, now it's loud as shit! I picked up some Borla Touring mufflers and haven't installed them yet but I know they will be even louder than the stock Bullitt mufflers. I'd like to add some resonators in the mid pipe but have absolutely no idea what type or brand to buy. There are hundreds to choose from.

Since I don't know of any good exhaust shops, I'll most likely cut and clamp them in myself. Then once I have them positioned I'll remove the pipes and take them to my welder buddy to weld them in place. I don't think I want somebody splattering welds all over the underside of my car.

I'd like to know this too, especially once I install the Paxton.

Thanks Brian, I didn't want to be the one to ask LOL!

I recently added 2 of these http://www.ebay.com/itm/2-5-x-18-Lo...Parts_Accessories&hash=item485b30ce76&vxp=mtr to get rid of my exhaust drone after replacing my offroad h with an x. So far, its doing a great job! money well spent.

Did those make the decibal level go down at all?

 

[james05gt]

A little bit but it definitely got rid of the raspiness. Gave my exhaust a deeper tone.

I have some m80's on my car. Sounds pretty good. Took the volume down a bit and cleaned up the sound. They are cheap too.

These resonators have been working great for me from JPC. Just use the drop down to choose either the 2.5" or 3" size. I would ask them if they will fit over the mid pipe or if they are the same exact diameter. If they are the same you could just pick up some stainless steel band clamps from your local auto parts store to temporarily hold them in place.

Brian how long do you want them 12 or 16?

16" 2.5" in/out 3.5" case
2520sb powerstick
63.33 each


12" 2.5 in/out 3.5 case
25-res
41.50 each

I've heard of a couple of guys destroying M-80's with FI. Just an FYI

I'm assuming the longer they are the more effective they are? The ones from JPC are only 12", I've seen others 16"-18". I've also seen prices from $40 to $120 or more.

I'm about to add some 3" resonators to mine. Once I deleted the cats, it got too raspy and loud. I'm hoping to tone it down a bit.

 

[JEWC_Motorsports]

Brian, the ones i posted i run daily on my car. I actually installed 2 sets of powersticks on my car, similar to the SW catback.

 

[skwerl]

I have no clue what a SW catback is. Do you have a link for those resonators?

Vibrant resonators are a good choice aswell, they also look super sharp

 

[skwerl]

When I looked on Amazon I found this one, a Vibrant 'ultra quiet' resonator. It also looks like I can possibly put it where the cats used to be. Reviews are good on it and it looks like several of you like the Vibrant brand.

Correct. Not sure how any of the ones below will affect hp but they may cut down on the noise.

I ordered and installed resonators from JPC, which I think were Vibrant brand I think, after I put the M90 on and went to a off road H. There was some rasp, so I had a shop weld in the resonators and the sound was cleaned up to be nice and throaty! I think you will be very happy if you choose to weld some in, I would suggest the welding vice clamping as it is just one more place for an exhaust leak.

Yup, 3'' resonators cured the rasp I got with Gt500s and off road x. It sounds nice and clean now, and it tamed the noise a bit too. Now I think I'll replace the x with an h....
