"Straight" pipes

Guys on the other forum were bitching about how loud muffler eliminators were but I tried them anyway and LOVED them! Might have liked it louder, in fact.

So, I'm really set on a Corsa system but just I'm trying my best to be pragmatic and give proper consideration to different options before pulling the trigger. Wondering about just modifying my stock system by replacing the resonator with an X-pipe and deleting the mufflers altogether...just straight black LT-1 tips out the back. The only "mufflers" would be the cats, just like on my '87. I see very little potential for resonance with this setup. VERY, VERY inexpensive system, good return of HP, lots of sound.

Remember, I like to HEAR my car. If I want quiet, I drive my Camry.

Thoughts?

Thanks!
Chris

Well I have used Corsa resonator in the attic

Thanks!

Oh yeah

Makes sense. Thanks Kevin.

Thanks Daryll, figured that would be the case. Not gonna do the Corsa resonator at this point. I think I'm really looking to experiment with some "cheap sound" here for a while and then maybe 4 to 6 months down the road, I go full-boat: Corsas and SW headers with no cats.

I have old style B&B, Watsons, X pipe. 3". Very loud and drones on the highway. just need a good radio with an amp.

Chris, I know you have seen my exhaust cutout post, and thanks for the compliment.
Let me say that with the muffler by-passed it is freakin loud, open header loud. I just ordered some 18" Dynomax bullet mufflers to help quite it down a bit. System closed going through mufflers is super nice and quite, almost too quite. I think when the cutouts are open it is louder than normal mainly due to my HP upgrades.
-Watson headers, X-pipe and cutouts @442rwhp = loud

Thanks for the input, Tony. I really loved the sound of my L98 running through only cats but consensus seems to be that an LT5 through just cats would be "race car" loud. Leaning toward just replacing the resonator with an x-pipe for a while, then doing the entire exhaust (SW headers with no cats and Corsa) 6 months down the road.

If your talking about a stock resonator being replaced with X-pipe it won't get that much more loud because if you ever have seen what is inside of a stock resonator you will see that there is only a small 4" length perforated section at the beginning of the resonator. The rest of the body is a solid pipe. Helmholtz design once again.

I have two stock resonators that I cut off and I was surprised that was all the muffling going on in there. It's design was to kill a certain frequency only that the mufflers didn't. The installation of a X-pipe will just flow better since it isn't at a 2.5" reduction like the resonator.

This is a stainless X-pipe removed from a 300 "Hemi" SRT. The pipe if cut just behind the clamps beyond the flange and just in front of the turn at the other end yields 28" of usable pipe. The pipe is 2.5"+ inside and can easily be expanded to slip-over the factory pipes forward and rearward of the resonator. This one was removed in a collision repair so the flanges and clamps were destroyed by the shop. The opening in the X is likely 4" X 1 7/8' or maybe just a bit larger. I would think it ideal for factory resonator replacement.

All of the MOPAR aren't X-pipes even though they're welded as such. I believe it needs to be a 300. MOPAR I was told felt that the weld of the intermediate pipes in this fashion helped control resonance regardless of whether it was opened or NOT.

Dynomax does a 3" system for the SRT and the X-pipe can be purchased separately in 3" aluminized pipe. It's a 54449 and depending on a relationship with a Walker jobber is maybe a possibility for a very nice 3". The Walker number hints that it's likely a 50"+ part, lots of material to work with.

Sweet, thanks for this info, Dave!!
