Ok do we have any Exhaust shop employees in the house? I have a question about my set-up that might also help some other Honda owners out there. My specific question is about my Del-Slow (though this question should fit Honda/Acura needs as well). Where is the optimal place to weld my resonator?

I've got my B16a Del-Slow that Im putting exhaust on. I picked up a Megan 4-1 GSR header (2.5" Collector), I am not going to run a CAT, I picked up a Vibrant Resonator (12" long x 3" inlet/outlet), I picked up a Kteller 3" stainless mandral "weld it yourself Del-Slow kit", and I picked up a Megan burnt tip muffler (3" inlet/outlet). Im going turbo with the del-slow soon, so please the exhaust diameter isn't debatable here, I just want to know, since I can choose anywhere along my exhaust system to place the resonator, where might it sound the best?

Of course I could put the resonator in place of the CAT. There isn't alot of information about where to place a resonator because most people buy an aftermarket exhaust where the manufacturer chose where to put it for you. Anyway, putting the resonator in place of the CAT, seems like the heat from the header might burn out the resonator prematurely. But would the exhaust system be louder (in-cab) with the resonator directly after the header, or might the In-Cab noise be lower?

Keep in mind that I can place this resonator vertually anywhere... So what would the system sound like (in-cab) if I put the resonator directly in-between the header collector and the muffler (with equil piping length in-between)?

Lastly, how would the sound change if I put the resonator as far back toward the muffler as possible? I would immagine that the resonator would last the longest back here, but I'd like to atleast hear myself think In-cab.

I came here for this question because we have some good information floating around this site. And hopefully other Honda/Acura owners who want to piece together their own exhaust, will learn from the replys given here.

 

I worked in a well known exhaust shop in my local area several years ago so I have installed hundreds of custom applications.

Since the system you are running is relatively small, on a Delsol compared to that of a Ford truck.. It should not make to much of a difference where the high flow resonator is placed because there is not that many sections on the pipe where it can go anyway, due of course to bends and length restrictions. If I were you, I would place my resonator where the original catalytic converter is or was for two reasons. 1. There is already a mold in your undercarriage to fit a catalytic converter.. this will allow you to keep your resonator tucked up in this grove for better ground clearance. 2. Some high flow catalytic converters come equipped with a welded bung in the neck before the flange so that you may relocate your sensor. (Not sure if this applies to yours)

Anyway, I hope this helps.

 

Ditto the above^^^, I put mine where my cat was, [94 Integra/5Zigen SS exhaust system, as mentioned, it will tuck right up there. 94

 

Thank you both for your intelligent and insightful input guys. I wouldn't object to anyone else chiming in here... Do most of you guys on this site have your resonator placed in place of your CAT then???
