    Thanks Mart, if I decide to go with an entire new system I will keep that in mind. You were able to get them to fit your n25 fairly easily? I do need new mufflers so it could be a good option.

    It's been years since I bought the whole system from Ramchargers. Abt $300 with long case 3 chamber muffs. Great price yrs ago.
    They fit well, that Amer. Thunder system gives you both tailpipe options, N25 or standard downturn.
    2-1/2" Aluminized mandrel bent, holding up well... may have different muffs now?, idk.

    I just ordered the tips in the first post and bought 2 replacement mufflers based off post #9 in this thread:

    I actually had to buy 1 muffler from amazon, and 1 from walmart. I chose to go with just the tips and mufflers because my down pipe/mid pipes are crusty, but solid. I have my original N25 tips to compare with the TPP repros. I do have concerns about the mufflers. They should be the correct 2 1/4" inlet/2" outlet, but the outlet is centered on my current tips, and the replacements I bought are offset. I will post up pics when I get everything installed.

    Assuming the tail pipe pictured is an original, I think it’s a decent reproduction. Not mandrel and not perfect, but should be serviceable. Total cost was 230 shipped. I should have them installed in a few weeks.

    Closing the loop here for now. Overall I think it’s a solid part for the price point. I didn’t spend much time adjusting it. When I get the car on a 4 post lift I can tuck it in more, but think it fits well. I wish I got a center outlet muffler. The right side exhaust is 100% original (except muffler) so it makes for a good comparison

    That Flowmaster system is designed for the N25 exhaust option. 2-1/2" mandrel bent, Aluminized, and I believe they sell just the tailpipes separately. I know the tailpipe needs to be tucked close to frame for tire clearance.
