Mach1 Driver 528 Report post Posted June 28, 2022 Mine is currently a 2v, so what tips were used on a stock Mach 4V? I've seen so many types, that I'm curious what is correct. Changing the rear valance is not a problem. Thanks guys. Quote Share this post Link to post Share on other sites
jmlay 76 Report post Posted June 29, 2022 All 69 Mach1 received the stainless rolled tips. The "exact" repo are quite expensive. But there are several lower cost alternatives.: https://www.npdlink.com/product/tail-pipe-extensions/214326/200414?year=1969 1 Mach1 Driver reacted to this Quote Share this post Link to post Share on other sites
69RavenConv 283 Report post Posted June 29, 2022 I bought a pair from an outfit in Michigan. The welds were pretty rough but can't be seen when installed. They were nowhere near $463. I will see if I can find the name, assuming they are still making them. [edit] I couldn't find my old post but I found another one. It's Great Lakes Customs in Mt. Clemons, MI. Looks like they are still around, maybe give them a call. 1 Mach1 Driver reacted to this Quote Share this post Link to post Share on other sites
RPM 1,157 Report post Posted June 29, 2022 Dude, you're about 6 months too late. I had a pair that I'd have let you have for my cost, $100. Crap! 1 Mach1 Driver reacted to this Quote Share this post Link to post Share on other sites
Mach1 Driver 528 Report post Posted June 29, 2022 Thanks guys, and wow you're not kidding- they aren't cheap! I'll try Great Lakes Customs. I assume that the correct valance would have the pass- though, since the tips don't turn down. Quote Share this post Link to post Share on other sites

Depending on the size of the pipes you're running, there are several tips listed on eBay right now. 1 Mach1 Driver reacted to this Quote Share this post Link to post Share on other sites
jmlay 76 Report post Posted June 30, 2022 Cheaper options do exist. Scott Drake has a couple of pair, Scott Drake C7ZZ-5258-C & C7ZZ-5258-GT2. Another option is United Pacific, FM003. All "correct" are going to fit a 2 1/4" pipe. Quote Share this post Link to post Share on other sites

Mach1 Driver 528 Report post Posted July 2, 2022 Yes they do, so they wouldn't be stainless steel, but still no rust after 50 years! They must have been sitting in a warehouse in Arizona ;) Quote Share this post Link to post Share on other sites
stangs-R-me 118 Report post Posted July 2, 2022 The "CORRECT" 1969 351W 4V and 390 tips have a 1-3/4" I.D. inlet, so even the stock 2" tailpipes used on 351W & 390 reduce down at the ends to slip into these tips. Front pipes & transverse muffler were all 2" as well ... the 351W H-Pipe on the other hand is 2-1/4". 1968-69 428 cars had full 2-1/4" exhaust from the H-Pipe to the tips. Instead of using the same restrictive and separate tips the 351W & 390 cars used, the 428 cars came with special 2-1/4" tailpipes with the SS. Twin Tips welded right to the end of the tailpipes for much better flow, picture & details here: https://www.scottfullerreproductions.com/catalog/item/4595229/4650641.htm Back in the 80's, I put reproduction big block 2-1/4" exhaust on my 351W car because I was told by the seller it would bolt right up to a stock 351W H-Pipe ... YES IT DOES. To be able to use the stock tips, I crimped the ends of the 2-1/4" tailpipes down to slip into the 1.75" inlets of the stock tips. My 1st set of tips were the Ford replacements that were just plain chrome plated steel (without the correct rolled S.S. tips), I got these in 1984. Once correct reproductions made of S.S. with the rolled tips became available in 2005, I bought a pair of these ... my chrome ones were pretty rusty by then anyway. In 2019, I bought a pair of the custom-made S.S. tips that are externally identical to the O.E. tips but have a 2-1/2" inlet and ZERO internal restriction like the O.E. tips have. They are works of art !! Cut my restrictive ends off of my 2-1/14" tailpipes and welded on 2-1/4" I.D. to 2-1/2" O.D. adapters and removed that bottle neck !! Read all the details in the thread I posted on the subject here: New '68-69 Rolled Lip Exhaust Tips with 2.5" Inlet - 1969-70 Technical Forum - 69stang.com and 1969stang.com The 1969 and 1970 Mustang Supersite Terry ... in previous threads, you have stated you want to put the largest size exhaust on your car that will fit for the least restriction, so you would then want to use these 2.5" I.D. inlet tips to finish it off and make it look stock !!

RPM 1,157 Report post Posted July 2, 2022 Great post and memory Dave. IF, I'd have run my exhaust out the back, I would've blended my stock tips to accept 2½ exhaust tubing. Quote Share this post Link to post Share on other sites
Mach1 Driver 528 Report post Posted July 3, 2022 Interesting- so the pipes were 2.25 but the tips were 2.5 and split into two. Too bad the whole system wasn't 2.5. Quote Share this post Link to post Share on other sites
