I have a little V-6 Coupe, White...Strut tower brace, K&N nothin' big....Havn't yet had a chance to get the Eibachs put on....Still in the box...Single exhaust...It is an AOD... It can get some giddy up on a good day......As for ET in 1/4..???? Good Question... Best way to settle any argument is line it up!....To spped limit....But a couple times can settle who's who....
IMO you guys were comparing apples and oranges though....
Good Luck.... ~Jenn~
AND BTW...I was just checking the specs on your car..LOL...OK... I can't even believe you LET this guy work you up.... It's a V-6 and second......Your car could be out of tune, missing a firing order with the caberator fuel/O2 mixture all F-up and and still probably wipe his butt! Trust me.I have a 98 V-6 Coupe and exhaust w/15-30hp increase is not going to bring it close to you man.....Relax...Take the high road. It's knowing what you have under the hood and being confident with it that counts.....Let him fry his engine trying to dog ya...and then fly by him waving and just laugh!
