I talked to TopSpeed's sales manager at the XDC event today, he offered me a great deal on the cats. Ill be going by next week, Ill let you guys know.

 

Keep us posted and let me know if you get any noise that sounds like an air leak or rattle snake. I am really anxious to find a solution for this obnoxious sounding rattle in my y pipe. So as soon as you install let us know and would high flow cats perform worse than clear test pipes??

 

boosted applications probably get the best gain with test pipes. N/A cars are decent, but you don't want to lose too much BP.

 

BP- back pressure?

 

yeah. sorry. im processing photos i took of my evo right now and im kind of excited. lmao


tell us how it goes with the topspeed pipes. they seem like a good company.

 

I make(put the Pt and Pd in) catalytic converters at my job and they are not as expensive as these companies sell them for. For a gasoline type vehicle usually $50 tops. I still say go for it, since you won't find any too much cheaper.

 

Wow these Cat's are cheap. Let's see how they turn out.

 

interesting

 

Amazing. The best car as a whole package on the planet. Sold it a year and a half ago to get myself ahead financially. I'll be in a position to buy another a year from now.

This Z isn't my first, but definitely the fastest. Could eat the NSX alive and then some, but they're two completely different cars.

Back on topic, I approve of TopSpeed stuff.

 

I'd like to get an NSX some day

 

Are these cats supposed to give the same HP gains as Berk or the other pricey ones?!

 

they probably give you more because they are cheaper lol

 

With the plunge their value took with this recent economic upheaval, there's no better time than now. I was lucky I sold mine for what I did right before the big bust.

Sorry for the thread jack haha. I really do have a bit of experience with TopSpeed and they make a good product.

 

yeah, unfortunatly im broke at the moment...id really like to get a 6 speed 3.2 anyway...gonna take a while for those to drop in price

 

You guys would be surprised at how much you really gain from HFC's or test pipes. A lot of guys claim 10HP, but i've witnessed plenty of dyno runs where actual gains are 1-2HP at most. Believe it or not, modern cats are pretty good.

When i was younger, i ripped the cats off everything, but now..i don't. My opinion is it's just not worth it anymore.

This is a test done by Grassroots Motorsports on stock, test and variety of HFC's. Test car was a miata, but still
