Yes I do, I have a 3" piece of straight pipe to do so but I haven’t yet. Actually, I had gotten a ticket for “inadequate muffler” or something because of it, even though it isn’t that loud IMO…but I guess since it doesn’t exit from under the cabin right? lol There is a muffler in the middle though, where the cat used to be. Being an '84, I only get Safety inspection not emissions, so… 🙂 ---

My car changed agian. I took the fender flares off, and the car got a bit more 80s…or maybe less 80s? Depends on how you look at it lacking the flares I suppose. Still need to smooth the 1/4 panels after filling the mounting holes from the flares, I should have just left them off. lol ![http://i929.photobucket.com/albums/ad134/SavannahZCar/Z31/100_3762.jpg](http://i929.photobucket.com/albums/ad134/SavannahZCar/Z31/100_3762.jpg) ![http://i929.photobucket.com/albums/ad134/SavannahZCar/Z31/100_3764.jpg](http://i929.photobucket.com/albums/ad134/SavannahZCar/Z31/100_3764.jpg) Temporary wheels with tires that actually allow the car to move in the snow: ![http://i929.photobucket.com/albums/ad134/SavannahZCar/100_3773.jpg](http://i929.photobucket.com/albums/ad134/SavannahZCar/100_3773.jpg) ---

> [@Sansone](#): > > I liked those flares They didn’t fit the quarter panels right because for proper installation you have to cut them, which I refuse to do…and in doing so, I could have made them work but I would have to modify the side skirts to be wider in the rear of them, and I’m pretty tired of fiberglass/bondo and sanding…lol Plus the fenders I had on the front had a couple creases in them and some dings…cars straighter this way and sooo much closer to paint. ---

What do you guys think about seafoam? I never tore this engine apart (it was low low mileage, under 100k) but it did have some carbon buildup in the intake ports (which I cleaned up pretty well) HOWEVER it is smoking a bit (it had good compression and such before I pulled it out of the donor). I’m sure some of the smoke is from my exhaust and the fact that the old engine had a blown headgasket, probably still some residue in there. Another small issue I need to work out is fixing leaks in the intake (MAF to turbo, and turbo to TB) due to crappy stock intake piping having lame ways of being sealed. I’ll be doing that by making a new FMIC setup and turbo inlet. Then again at the same time, it could be running lean due to the leaks in the intake which may cause some smoke possibly? My wideband isn’t hooked up yet. ---
