Resonator delete and x-pipe - Benzworld.org

1 BAD BURB · 09-13-2006, 07:16 AM

i searched the forums, found some info on it, but not specifically what im looking for. i know resonator delete will defintly help it sound more throatier and give more power, as will an x-pipe install... question is... does anyone have real world performance numbers??? Omey-homey???

also, anyone have a sound clip or vid of their exhaust after those mods?
im going to try and do this mod here in the next week or so. Anyone...please, advice? comments?
Thanks!!!

guys, i just spoke with my mechanic about this mod... the x-pipe is worthless. the two pipes crossover inside the muffler so there is no point.

another thing, what is the diameter of the pipe? anybody know. the section right next to the resonators?

thanks!

no flamming but whos interested in x-pipe anyway? oh wait I forgot omey jk -

hehe your cool omey

X-pipe is not worthless. Im going to do the X-pipe, its a necessary mods on V8s and it will make good gains, I will get dynos of course.

Theres no info b/c its never been done before on W210 to my knowledge, i searched for hours on multiple forums and no mention of it at all. I will do measurements today to see how viable it is but i think it should be a perfect fit.

...........ok, exhaust mods in a NA car DO NOT yield any HP gains........gospel!!!!! I have done the resonator delete and experienced no HP gains. And my car is superchaged. No HP gains from removing the resonator in a NA W210 will be expected. You do gain a bit from weight reduction. I have not done the X-pipe because like someone else has said, it is a waste of time.

yes Ted but what you don't know is on all the supercharged cars the exhaust is all straight through design, on the 2002 prior cars it was not. you get ZERO gains on all the 55 supercharged motors b/c the exhaust is already as free flowing as its going to get. the older AMGs thats a totally different story, the exhausts are not a straight through design, neither is the resonator. so you cannot compare apples to oranges.

I believe a lot of Vette guys install x-pipes in their NA LS1/LS6 Z06s and see gains, though I don't have any dyno charts or anything. The weight reduction and sound make the resonator delete mod worth doing, regardless of whether or not you gain any HP. My car put down 5 more HP and 8 more TQ then Hai's on the dyno on Saturday and they are basically identical cars (both 2002). Only difference is I have K&Ns, resonator delete, Magnecor wires, Denso Iridium plugs, colder t-stat, and ported throttle body inlet. Not sure how much of that is from the resonator delete since I didn't do before/after dynos. If you do the x-pipe, please get it dyno'd before and after to quantify any gains

Gospel according to Ted anyway, Thanks for clearing that up, I was about to do a resonator delete but having 2nd thought of it.

Take care & enjoy the ride,

All I know is that in comparing Jeremy Dyno number to mine, both done at the same place (Dynospeed, on a Mustang Dyno) that he has a little more HP than mine. We both have the same year with approximately the same mileage (02). The obvious difference that I saw was that my A/F ratio at the the top line is very rich compare to Jeremy, mine was around 12 and Jeremy was in the 13. So If I can get more air flow to the engine at the higher RPM, I expect to see the same HP number at the wheel. First I will check to see if my air filters are dirty, so I can easily change out the MAF, add the K&N filter and do the resonators delete and if I get the same HP as Jeremy, then it will be pretty clear.

..........you are actually wrong. Exhaust restrictions do exist in the W211 E55. Infact the reason many W211 E55 owners don't get exhaust mods is that loss of those restriction points can cause you to loose boost and may have the adverse effect on torque numbers. But forget all of that.........I don't have a W211 e55. I have one of those older AMG's you speak of. I have a W210 E55.
