Hello I am new here so hello my hello monte lovers! I'm looking for opinions and some guidance. I've had my 2005 Monte Carlo LT for about 8 months now she's got close to 90,000 miles on it and I have pretty much done everything that I could in order to restored to Perfection on most except for some minor cosmetics and I haven't touched areas that I am thinking of aftermarket possible items. My question is what are some things that I can do in order to increase the performance without breaking the bank I guess you would say. I have already replaced the resonator because the original had a leak in it but I really had no bearing. I'm looking for suggestions on things that other people have already done. I love this car and I feel like it's definitely worth investing in.

 

Here's a big thread with a ton of information about modifying your 3800: https://montecarloforum.com/forum/en...-bumpin-24896/

 

Assuming that this car has the 3400 motor in it? If you haven't done it yet a dual exhaust would be a good start.

 

2005 added the LT trim with the 3800, all SS in 2005 were L67s.

 

I'm sure it was just unintentional wording, but modding cars is almost like an anti-investment. Almost every dime you put into mods will be near completely lost.
