I am new...Need some advice...
 

I have a 2004 Monte carlo LS... yes the LS was going to buy the SS but found it was only 20HP between the two...but here is my question...what the the best way to get more horse power with out doing enine work...so i guess I am asking for the best bolt ons...thanks...

RE: I am new...Need some advice...
 

hey, welcome to the site :)

best and most cost efficient way for horsepower right off the bat would be

[ol][*]high flow cat[*]u-bend delete[*]get rid of resonator[*]3"downpipe[/ol]search around the forum on u-bend delete and you will find lots of info...you will probably gain about 10hp out of this..or close to anyway

RE: I am new...Need some advice...
 

Would a 2.5" downpipe be better?

RE: I am new...Need some advice...
 

what size is it stock?? i thought it was 2.5 stock...

the downpipe isn't really that nessesary

steps 1-3 do the most :)

RE: I am new...Need some advice...
 

i would say 2.5 because the stock one says it is 2.5 but it is no where close to that also it is ribbed on the inside of it and not smooth at all.

also i think the 3" one would not have enough back presure so you would lose a lot of torque

RE: I am new...Need some advice...
 

Your right on the money with this. DigPhoenix took me to task on this one awhile ago. :) The 3" downpipe is for Supercharged or other Forced Air vehicles. 2.5 for NA.

Also a really good upgrade is just droping in a K&N drop in filter. I would recommend a CAI or FWI.

Hey thanks alot for your help guys and i will look into this u bend thing...

RE: I am new...Need some advice...
 

ok this may sound funny but what and where is the u bend...and what does it take to get rid of it...

RE: I am new...Need some advice...
 

you take your car into an exhaust shop...

the u-bend is a part between the cat convertor and the resonator where the exhaust does a "u" for the o2 sensor and is very restrictive on the exhaust flow...most exhaust shops will know what your talking about

RE: I am new...Need some advice...
 

Ok that is great thanks... another question/problem i have been looking for exhaust parts but all i can come up with is the stuff for the 3.8L and not the 3.4L do the interchange?
