Hey everyone,

I thought I'd share my good experience with Bob Melton and his downpipe for the VR4 & R/T TT. I recieved my product on time as promised, complete with no missing parts, and installed it today. I took my downpipe off and melton's downpipe bolted right up without any problems what so ever! I know that people have had various fitment problems with other downpipes such as the DN Performance one as well as the ATR... so I just thought I'd let everyone know that the melton piece is a great product, and Bob has been great dealing with. Very straightforward, with no non-sense.

Judging from your pics, I don't see how this downpipe improves performance other than removing the cat. The design looks just like the stock DP. Am I missing something here?

I dont like it much either. I guess its an improvement over the stock, especially for the back 3 cylinders. i read someplace that this has no performance disadvantages over the "normal style" aftermarket DP, but its just looks too awkard/ugly. i have been looking for some picks and feedback on the DP from http://www.tyspeedperformance.com/
but I guess its a new product and not a lot of people have them yet.

The Bob Melton downpipe eliminates the T that is in the stock downpipe and gives it a more fluid, Y shape.

I ordered my Melton downpipe and testpipe with the 1st revision styling. Different than the version Marcus Frost has. See pic:



I love it. It installed EASY and the performance helped me gain .5 sec on my 1/4 mile time (not track time - time according to my turbo timer) from 12.82s to 12.34s. The higher RPM band seems a little more responsive now. Sound isn't much different than my stock setup until I hit 3000 rpm then she growls a bit more.

Recommend this downpipe and testpipe to anyone, VERY satisified with Bob Meltons work and service. Great work.

As turbo tension said, the way the pipe coming from the rear cat flows into the pipe is much better than the T from the stocker - you cannot really see it from the angle of the picture.

The piping is also larger @ 3", up to the rear section where it narrows back down to the stock 2.5".

For $280 including gaskets and the test pipe... it was not a bad deal at all IMO.

It looks good to me. Hey, as long as you're satisfied, that's all that matters. You're the one driving it in the end! :bigthumb:

I don't have a clip of the sound with my Melton downpipe and testpipe, but I can tell you what it's like. I have a stock catback and precats that are NOT gutted.

The sound at idling isn't much different at all, maybe a tad improved but hard to tell. When you get about 2900 rpms or so, especially in first gear, you can definitely hear a different, sounds louder, but doesn't sound bad at all. The difference isn't enough to irritate neighbors or anything like that by any means. So if you're looking for a LOUD exhaust, you won't get it with this combination. You will however get a little bit of a nicer growl with acceleration. Anytime your WOT it sounds much nicer too. Standing cruising speeds have NO resonance or noise in the inside cabin that I car hear either.

I'm 100% happy with the results. Flow is improved, my times are improved, it pulls harder, sounds nicer, etc.

I like doing all my mods in stages basically. After each upgrade I take the car out for a few test runs and time my runs with my turbo timer to determine the upgrade's effectiveness. Also like running for a few days to find out if any potential problems creep up before the next stage is tackled.

I'll gut my precats this spring most likely. I'm in no hurry since I don't drive it during winter.
