ok,right now my car has a dirty open element and hooker catback that leaks and the cat is probbly clogged,lol

im upgrading to longtubes,xpipe,turbo mufflers and a 10 bolt 3.23 LSD rearend(instead of my pegleg 2.73)

this is a 700r4 car

i run high 15s right now.....how far u think this will drop me in the 1/4 and just power gains all over.


im also putting in eibach sportlines and KYB gas shocks

 

If the car still has the stock manifolds and y-pipe, it could help a lot. Throwing darts here, but I would reasonably expect at least maybe .5 secs or so off the 1/4 mile time. Maybe even high 14's with everything else stock. If you did some tuning + peformance intake, you could probably even get even more out of it.

 

thanks for the reply

but that deff sounds great....yea my car all stock aside from whats listed(and has a/c delete and smog delete)
