Wats up MC fam i wonder if anyone with a supercharged monte or anyone that knows someone who did any mods...I do have a couple of specific ?s...Well i just purchased the wizzaired cai and k&n filter hopefully i can put it on this weekend..I also purchased autolite 104 sparks plug and looking for the best deal for spark wires...my biggest question is about the exhaust system...im a college student so im not going to go with a whole new system but I would like to know what excactly is the downpipe/u bend delete cause I asked a muffler shop and he had no idea.. and maybe best performance/soundly mufflers..and if i do that do i have to get a cat-back system..well if i messed anything up let me know and if you have any other ideas let me know i want to do a lil more wrk under the hood before i make it look even better...thanks a whole lot..

 

you can get a down pipe that gets ride of the ubend that is after the cat where the second o2 sensor is. that will free up the exhale of the motor the catback system you can do it a couple of ways what i did was have a muffler shop and have them make a y to make it a dual system. if it is already a dual systemyou can go to a muffler shop and have them put on some aftermarket mufflers where they can cut and weld in. as for the spark plug wires the stock ones are pretty good i know the original ones are better than the ones from msd ignition. also the coil packs are really good because some mc guys here are pushing some great hp with it as well as the stock wires. my question is your mc ss supercharged or is it the 3.9 or the 3.8?

 

Nice- you'll love it!

Return them, a 104 is too cold- you don't have near enough mods IMO. I think 606 is the stock heat range- 605 should be one heat range cooler than stock- that is where you want to be, 104s are 2 heat ranges colder than stock, and given your few mods is too cold.

What is wrong with your stock wires? If they're in good shape, leave them- if not, just buy regular OEM replacements. There is no extra power to be made with plug wires.

He should've been smart enough to know what a downpipe is. Ubend is pretty vehicle specific to us.

Go to www.zzperformance.com and look in the exhaust section- buy a downpipe, and it will literally bolt right in. You can also get them with or without a cat- and it will get rid of that ubend restriction.

The ubend is the little hump behind the cat to protect the rear O2 sensor- when you take your old downpipe off, you'll see it.

Don't buy mufflers for performance- your stock catback is not a restriction, and buying one muffler over another because it will give an extra 1/4 hp is not worth it- look on youtube for "GTP exhaust" to hear engines like yours with various exhaust.

If you're on a budget- I would do the downpipe for sure since that will gain you performance. Then, if you want to change the sound- find some mufflers you like the sound of, and just have an exhaust shop stick on new mufflers/tips on for you. That is about the cheapest way to change the sound.

There are lots of engine mods you can do (look for the sticky about 3800 modding- it has a lot more suggestions for your specific engine).

 

I appreciated the info already thanks alot everything is becoming clearer..well i have a mc ss supercharge the imtimidator model...hope that helps but about the spark plugs would it hurt to keep them i scored them off a website for a buck 50 a piece maybe for later used once i do more mods..im asking...and i will keep the spark wire just thought it may be better to get some better ones but i'll take your advance and save 60 bucks..now i think i seen the downpipe on the website and is it about 80 bucks if so thats next...now when it comes dwn to the muffler i like a couple like flowmaster and magnaflow but dnt know which one is for the monte i already have dual pipes anyone now the series or number for any..also if you know any more simple mods because im looking to do so work but one thing at a time thanks again

 

You could just keep them, $1.50 each is about average for them at normal parts stores- regular copper plugs aren't that expensive, hope you didn't have to pay shipping on them.

Just go to a local parts store and pick up one heat range colder (605's?).

May as well just get a bolt in on so you don't have to mess with having it welded in and such.

There isn't a specific # or series for the car- if you know that you like a certain series flowmaster or magnaflow- then go to a local exhaust shop and they will be able to install the style that fits your vehicle.

Did you read the sticky? It pretty well covers the basic mods.
