I like your grill, how did you get the peices of plastic out? with a cutter?

 

what kind of exhaust was your old setup, did it help any?

Are you willing to sell it? :

 

I say keep your dual exhaust. NOBODY has dual exhaust.

 

it has a good sound to it, i will sell one of them it is not a catback just a muffler, and i will sell it for ummm..... 85.00 + shipping, i paid 190 for it in january

 

but for performance i just want it to sound and give me a lil more juice i think it is breathing way to much from both sides.

 

looks good man take more pics once it come sout of the shop

 

will do i have the ss/sc as well i will take some of them side by side, both are black.

 

i used a dremel and cut them then sanded them with the dremel

 

did you also have to repaint the ends where u sanded? did you have to take the bumper off for this?

 

no, what i did is pulled out the clips that hold the grill on the front and pulled the whole gray grille out.... then cut all of the plastic out of the middle and sanded it down even. then cut the cross bar out with snips then used touch up paint on the sides after i sanded the even witht the bumper... the took the mesh grille and measured it even to fit perfect. then used a rubber strip arond the mesh so it wudnt scratch the paint and. then glued the grille down and under the hood i used a rivet gun to tac it down so it wont move. worked out great......

 

You have a 2.2 - you're not going to get much out of ANYTHING unless you go forced induction.

 

Thats some good info, you should post something like that up in the How-To section.

I might do that to my car one day, thanks bro!

 

i will do a how to shortly........

 

yeah I don't see you really seeing much of a difference

I thought about downsizing to a 2.25" exhaust from 2.5" but I'm afraid I wont see much if any change and it'll just be a waste of money.

 

If you dyno'd you might see i difference but butt dyno you won't

 

u think i shud stick with duals?
