Just found out...you want fan turn on at 185* or your fans will be on all the time.
And the thermostat will be beneficial...just get a tune. Without one you will only notice it while cruising on the highway IMO. Get you 3" Downpipe before that...the downpipe is a way more important mod than a thermostat...although you can get a t-stat at a local auto parts store for about 5 bucksGet some colder plugs too...autolite 104's...they're cheap too...prolly about 10 bucks or so for all 6.
Ok. Downpipe sounds good. Ill have to look for the price. Also I have no idea how to install one myself. Ill ask a friend of mine if he ever did that b4. I have the worst freggin luck with stuff. Nothing ever goes smooth for me. Lol. Ill try to replace the downpipe and the whole exhaust will fall down watch. Lol.
